Hi there, perhaps a strange question: but does anyone know if the LXD
500 mount with the # 1702 motors and control panel can be used with the
autostar (I have the new software version)?

Thanks for providing such a useful website

I have just purchased, via eBay, an ETX 90 EC with autostar controller
and various other add ons. From looking at your website I see how
important it is to train the system. I set up to do it last night,
plugged in the Autostar to be horrified to read the message USE ETX

Is this a fix that can be remedied via a software download, or do I need
a new controller? Over here they cost around $195 so I would much rather
have a fix than have to spend more.

Or would Meade swap? The autostar is " as new" - has not been used prior
to my attempt.


Mike here: Can you get to any of the Autostar menus to set the telescope model? If not, you can make or buy the Autostar #505 cable (see the Autostar Information page) and if you have Windows, then you can update the Autostar to the current software (recommended). You will probably have to put the Autostar into SAFE LOAD mode (hold down the ENTER and SCROLLDOWN keys and then power on) before the Autostar update software will do its thing.


Thanks for the swift response.

Cannot get the Autostar to do anything after the message displayed; I
will get hold of the cable and update via Windows and the web.

I really am impressed by the site - not just flattering to get an
answer! there is a wealth of knowledge there and it exudes enthusiasm. I
am trying to get hold of your book, looks like I will need to order via
the net.

thanks again

Nice site...your advice in the past has helped me immmensly in
understanding the "mighty" etx.  I am still unclear on manually adding
objects to my autostar.  I can download new "patches" from Meade and
load them into my 497 but how do I do It manually?

What if I downlead just one ephimerides (sp?) - can I download it ino
the 497 or do I have to enter it manually?  How do I know it is in the
right form?

Sorry for so many questions..I do understNd the astronomical terms fully
that the Autostar asks for and am not familiar with their typical

I cant seem to find a contact at Meade directly and keep finding your

Ever since I downloaded and installed my first updated AUTOSTAR
software, it doesn't seem to work anymore. Then again I am not sure that
it ever did before either. I am now running version 25Ea, downloaded on
26 May 2002. I am located in Melbourne Australia. The previous download
was 22Er, unfortunately I don't remember the version it had from the

My symptoms are as follows:
- After initialization I put my DS114 in home position, i.e. level and
facing north.
- Using one star alignment and selected Sirius (tried the other methods
as well but had similar problems).
- Autostar starts moving and keeps going 360 plus another 150 odd
degrees in an east bound direction. It almost turned 1.5 rotations
winding up the cable around the tripod.
- It pointed nowhere near Sirius' direction. The altitude was maybe half
of that required and the Az was around 150 degrees off.

Is it possible that maybe the gear ratios became corrupted through the
downloads? Are you aware of problems like this? I would appreciate if
you could give me some tips or point me somewhere (web site, news group
or similar) if you don't know the answers. Is there some method
available for tuning the drives, i.e. find out the gear ratios?

Best regards,

Mike here: After you updated the Autostar, did you do a RESET, reCALIBRATE, and reTRAIN? Did you check to be certain that the right DS model is selected in the Autostar? If the answer to all those is yes, you'll find some potential help on the Autostar Information articles.


Thanks for your quick reply. I did not do the reset and calibrate after
my first download (to 22Er) some time ago. But this time (to 25Ea) I did
choose the automatic "RESET" from the updater. It must have worked as it
ran the calibrate automatically after the download. I also needed to
re-enter my details, location, city, telescope type, etc. I ran the
calibrate a few times from the setup menu. However, I did not run the
TRAIN. So I went and did it tonight.

The results seemed promising at first. After a few more calibrations I
used some distant conspicuous city light, about 35km away, to train the
Alt and Az drives. After that I used "one star alignment" using ACrux as
it was nice and high tonight. Although the altitude seemed to be spot on
this time, the Azimuth appears to be still about 60degrees out. Its
better than before, but obviously no way good enough.

I repeated the drive TRAINing with my high power eye-piece, but without
success. What I did note, though, was that using #5 speed the telescope
did not move in Az for quite a while despite the motor humming away. It
appears to move alright in one direction but to be "sticky" in the
other. I was suspicious when I first got the Telescope about the axis
nuts. Despite being very tight, there seems to be quite some backlash.
The whole telescope seems somewhat flimsy in its mounting.

I'll have a sticky beak around your web site (It looks quite
impressive!) to see if there is more information that could help me.

Thanks again for your support. If you have more ideas about my problem,
I would be glad to hear from you again.

No... i've been looking into it... and still haven't discovered if
the display chip has a "shift" mode to bring in any other characters.

Some feed back on the up date of my Autostar .

I purchaced a second hand ( although brand new and sealed in its Meade
box ) 495 system and made up my own computer cable ( 505) . Successfuly
down loaded the latest updater from Meade and today got up the guts to
do the actual up date .

Plugged all together and powered up the Handbox with the complete 492
motor set attached . Connected to the net with explorer and brought up
my isp's home page ( which I minimised ). Ran the updater and it
searched the web for Meade and down loaded the latest Build.rom file .

When all onto the pc it asks to update now and I say yes . It initially
couldnt find the handbox but did in the end , and then could not
transfer the file ( should I have set up the hand box to the" Down load
" section of the menu ?)

However , reading from the net I put the box into safe load and tried
again , Hey presto it runs the down load and udates my hand box .( truly
glacial rate !!!)

Now for the questions .

Like somebody else I ve read about , at start up the screen is nearly
completely whited out ( full brightness) on the left hand side , but as
you run through the commands ( you can just about make them out ) and
get to the Align set the screen drops back to the brightness and
contrast set ? strange ? and the plastic below the whited out section of
screen gets warm . As soon as you get to a normal display ( after align
, it cools back down ) cant think why this is happening  ?

My hand box was version 1.2 and is now version 2.5Ea , does this just
refer to the data base ? or have I successfully morphed my hand box from
495 to 497 ? how can I tell ? if not how do I go from here ???

By running a safe load have I only up dated part of the system ?

So far so good  , Wonderfull machine . Great web site.
Mike here: Bottom line: as mentioned many times on the ETX Site, 495 Autostars can be updated to 497 Autostars by running the updater application. So, yes, you've updated the software and data to the current version and now have a #497 Autostar. The reason the download didn't start is that versions of the Autostar ROM older than 1.3 (I think it was) do not support the automatic download mode. Once upgraded to the current version, it should no longer be necessary to manually put the Autostar into download mode. You can adjust the brightness under the Utilities menu.

After you talk to Meade about repairs, and if they wish to charge,
you may find it cheaper to simply buy a new Autostar on the web.
New-in-box from (495's for $50, upgrade to 497).

I solved the problem. I hadn't yet tried connecting to the Autostar
using the latest Autostar application, so when I did, the Autostar
didn't initially connect, but after doing an automatic com port search
(a great feature!), the Autostar application identified the right com
port as Com 4. The default com port for Cartes du Ciel is Com 1, but
that program will NOT search for an available com port! So, I just
changed the com port to Com 4 in the Cartes du Ciel port configuration,
and all is well.

Arcturus and is off center a good bit and the same for Capella. My
tripod is level and in the proper position. Any ideas?
Mike here: There are many variables that will affect the positioning of the alignment stars. Check the initialization settings (date, time, AM/PM, Daylight Savings, location, telescope model/mount). Also, be certain to use True North, not Magnetic North (unless you know the Magnetic Variation for your location is zero or small). Of course, most of this won't matter once you center the proper alignment stars but the more accurate the settings and Home position, the better the starting conditions, and hence the better the pointing to the alignment stars.

An interesting situation came up this weekend.  I was trying to load the

etc. It turns out my flow control setting was messed up (I have no idea
how). Anyway, I had exited the updater which of course makes the
Autostar hunger for the flash load mode.  I fixed the flow control
issue, and ran the updater and loaded the Autostar successfully in flash
mode.  I then asked the updater to download any tours from the Autostar
and imagine my surprise when I discovered that all of my tours and
settings had been preserved.  I guess I hadn't written over those
databases.  Looks like the moral of this story is that after a flash
load, check to see what is in the database?

After a slow start Im now the proud owner of a meade Autostar 495 , wow
what a tool .

I brought some  of the DS motors as well ( the complete 492 set ) and am

people on the site have had different experiences  and as a newbie to
this area would like to get off to the right start .

I am adept at electronics and can make or buy the 505 cable .

What to do next is the problem , there sems to be too much info around

How up to date can I make it ?

Mike here: Make or buy the #505 cable. Get the Autostar Updater application from Meade's site and install it on under Windows. Connect the Autostar to a serial port on your computer and power on the telescope. Run the updater application. It should detect your Autostar and display the version number. You can then just update it. If the Autostar does not automatically go into Download Mode you put it into that mode from the Setup menu on the Autostar and then do the update. For more info on the process see the article "How to use the 3.x Updater" on the Autostar Information page.

Many are the Japanese kana set.
I went through Victor's list, and have added a few more annotations.
Some of the characters are from the original IBM PC Graphics 
character set (such as the squared corners, and block-backwards-F,
and the two every-other-pixel filled character cells.
I added some more Greek identifiers, and capitalized the ones which
 were capital letters. (Phi vs. phi)

One problem Mike may have is that some of the characters are -not-
the same after being processed by a Macintosh.

The Autostar's display is an off-the-shelf LCD display module.
The manufacturer will have character encoding charts... we only
have to determine the make and model, and a chart is probably
easily available...  time to go digging...

From: (Ted Wilbur)
I've been experiencing sporadic motor unit failures with my ETx70.  Here
are the symptoms:

If Polar mounted I'm guaranteed to get at least 1 MUF during the course
of a 2 hour session.  Once it happens, I'll get them regularly (within
10 minutes or less after the first one).

Switching mount to Alt Az cures the problem, I've only received 1 MUF
ever in Alt Az.

In either mode, the problem only occurs with the SAC7 in the eyepiece
port, and only when tracking a target (i.e. slewing with the camera is
ok, and the problem never occurs when just using an eyepiece).  I'm not
using any counterweights, but the balance of the OTA seems perfect with
the camera on board. With the Alt lock completely loose, the OTA will
stay wherever I put it when the camera is in place - without the camera,
the front (lens end) of OTA always drops down.

I opened up the base and did a degrease (wasn't much there) and
tightened the RA bolt slightly, no luck. I also tried a polar mount
reset/retrain but the problem occurred again during the very next
session. I may have messed this up, is it reset-recalibrate-retrain, or
reset-retrain-recalibrate (I did the former).

Any ideas?  I'd really like to keep using polar mode as I'm hooked on
imaging and it seems to allow me to take higher quality long exposures.

Mike here: Does the problem seem to occur at a specific orientation? For example, does the problem occur when the telescope is pointed east or west? If so, perhaps the telescope just has a problem tracking with the weight in that orientation. You should recalibrate, reset, and retrain but if there some "dirt" on an encoder that won't help. You might be able to cure the problem by just moving the telescope by hand in both axes from stop to stop. That may clean off any contamination on an encoder.


You are the MAN with those fast, thoughtful responses Mike!

I haven't discerned any pattern yet, and have even recreated it several
times in random positions just letting it run inside the house.  The 70
doesn't have hard stops, but I could move it around both axes, haven't
tried that.  When I had the base open the RA encoder wheel looked clean
although I guess the encoder itself could have some dirt.  I'm not
anxious to open the fork arm so any problem with Dec grease or Dec
encoder will get by me.  Sounds like I didn't do the reset right so I'll
try again in the order you suggest.

Hoping for the best.  As always, thanks a lot!
Mike here: Oops, yep the ETX-70AT doesn't have stops in the azimuth but the altitude range is limited. Anyway, just moving back and forth through several full rotations in azimuth might help.

But -that- is "merely" a parameter-keyed lookup through the NGC and

you see "start search".
If you tap scroll down, you're offered "Edit Parameters",
tapping [enter] there gets you into the long list of object types,

Subject:	autostar firmware enhancement suggestions
Sent:	Thursday, May 16, 2002 14:04:07
From: (V.A. van Wulfen)
Hello Meade,

As a user of an ETX-125EC with a #497 Autostar I have some suggestions
for enhancement of the controller's firmware.

Recently I discovered, while writing my own tours that the Autostar is
capable of generating symbology/characters which are not listed in the
controller itself (e.g. when entering user name/adress). It is capable
of reproducing most characters entered in a text (ANSI) file using
[ALT]+[number]. However, some symbols show up differently when uploaded
to the controller. [ALT]+133 shows to be "" in the text file, but
displays as the Greek letter 'alpha' in the controller. Not a nuisance
at all, actually an opportunity to enhance my tours by inserting
characters instead of words! To this e-mail I have attached a 'tour'
that can be uploaded to the controller to see which symbol gives which
character in the Autostar display, as well as a list -Word file- of the
results I got. I know when Autostar first came out it supported multiple
languages. However, I have not yet learned about the capability of still
generating non-standard symbology. I actually ran into it accidentally.
My suggestion for improving firmware is to enter the entire greek
alphabet, as well as astronomical/scientific symbology for people to use
in their tours, simply by keying in the correct [ALT]+[number] in the
text files. For the time being I'll use the symbols as per attached

My next suggestion has to do with tour writing as well. Meade's object
descriptions present multiple 'menu's' which can be accesed using the
scroll buttons. For example: Double star's magnitudes -scroll- Class
-scroll- Separation -scroll- Distance, etc. It would make a great
addition in tour writing if this feature could be introduced to home
made tours. I write my own tours, using multiple objects with my own
descriptions in my native language (Dutch) and would like to be able to
introduce this feature.

My final suggestion has to do with you latest firmare enhancement,
introduced in 25Ea: Rise time for all objects. A usefull addition to
this feature would be a rise time for a specific altitude. Any Autostar
user that has part of his horizon blocked by structure of any kind could
use this. As nice as the feature is, its use is limited when there are
mountains blocking the object from view until more than an hour after it
rised. If an Autostar user could tell the controller to predict a rise
time for rise+20 degrees, or any other amount, it would make a major
difference. Observing is very poor anyway for objects close to the
horizon. Maybe you could even make it possible to enter the degrees to
add to rise time for several directions of the observing site (north,
east, south, west, for example).

Hopefully these suggestion will be taken in consideration. I'm looking
forward to future releases of Autostar firmware, as well as your reply
to this letter.

if you enter the current DST time, do you also tell autostar "yes" when

2.4Ea) and still get the same result.


Do you have any suggestion?

Pierre Cote
From: (Richard Seymour)
I can think of only two things which might cause this: bad memory in
the Autostar (which means: call Meade, request replacement), or 
simply a (somehow) confused parameter memory.  
Whoops: three: bad communication between Autostar and telescope.

Try this: instead of entering any valid time/date/daylight,
try pressng [mode] to escape from those questions.
Then you may be able to scroll to Setup > Reset
at that point press [enter] twice, and the Autostar will try to
adjust some of its memory to a "factory default" condition.
Then, if it happens again, do the same escape-with-mode,
but this time scroll to "Setup >  Telescope", press [enter]
then scroll to "Calibrate", and press [enter]

The telescope should make a short motion with both motors (one after
the other).  If it doesn't move, something is wrong in the scope
(or the Autostar's communication -to- the scope... you could try
swapping ends of the cable)

If escaping from date/time/daylight still leaves you frozen,
i'd try swapping cable ends.  If you have the little "hand controller",
does -it- cause the telescope to do the short up/spin motion on powerup?
If it doesn't, then i would suspect the telescope.  If it does do that
motion, then the Autostar (or the cable not being seated firmly) is
the likely culprit.

If you bought your ETX125 used, you can replace the Autostar for about
$50 from vendors such as

Good luck
And this in response:
Good morning, and thanks for the suggestions.

Suggestions 1:
When I press MODE, it keeps going to the next question, and ends-up to
the daylight question where it hangs.
NOTE: When it "hangs" on the daylight question, the arrow keys still
move the telescope.

Suggestion 2 (bad memory):
This is not funny. It is a brand new unit... On Thursday, I purchased a
ETX105EC... When I got home, the vertical motion was severely limited:
The mechanical stop was malfunctioning.
The dealer ordered a new one. On Friday, it arrived ... with the
horizontal motion limited: Another broken scope. I decided to change to
a 125 the dealer had in the showroom. This would be the third hardware
problem "out of the box" in a row.

Suggestion 3:
Since I can still move the telescope with the arrow keys, I conclude the
communication is happening correctly. Not to be stubborn, I tried it: no

As much as I would like to "reset" the Autostar, I can not get into the
menus to do so.


Thanks for the help,
Pierre Cote
Mike here: Sorry you've had all these problems. As to the Autostar, perhaps you have corrupted download ROM files? Try grabbing a fresh one from Meade's Site. Then force the Autostar into SAFE LOAD mode (hold down the ENTER and SCROLLDOWN key simultaneously and then power on the ETX). Next, launch the Updater application. It should detect the SAFE LOAD mode and let you proceed from there.

And the saga continues. This from Dick:

Sigh... i was afraid that would be the case (i didn't have a chance
to pre-test with my scope before answering)

> Suggestion 2 (bad memory):

Ouch... there have been other folks who have also gone through a 
sequence of scopes trying to find -one- which works... 
At least talking Meade (or your dealer) into swapping Autostars
is much more casual than shipping the scope back.
The Autostar is a separate beast, even though we tend to view the
two objects as a system.  In fact...
The next step the Autostar does after the "daylight?" is attempt
to interrogate the scope about its "motor type" and send the stored
calibration data to it.  If either of those steps were messing up,
it could conceivably hang (especially on first power-up from brand
new).  Since you -updated- your Autostar, i was assuming that the
entire scope/autostar system -was- working properly before the Update.
Please advise if not, or if not tested before updating.

> Suggestion 3:

I fully agree with your assessment... another button-press to try 
(before the next paragraph) is to hold the [mode] key down for 3
seconds, then release.  With luck, you'll reach the RA/Dec display.
Scroll down once (or scroll lots of times and see what -all- of
the status readouts say) to the Alt/Az display.
Verify that they change reasonably as you slew the scope with the
slew keys.  (the displays may not update -during- the slewing, but
should readout properly within a second of releasing the slew keys)

Two:  the second of which is complex enough i'd have to go offline
to write up a how-to, and its function can be partly achieved by the

The "easier" one is to "simply" re-update the scope with 25Ea.
I remember that your original posting talked about reloading older
versions... and since it seemed to do that happily, i didn't suggest 
it the first time through.
But -this- time, when updating, choose the "Verify Downloads"
item under the Options menu in the Updater.  That will more than
double the time required by the Update process, but will verify
that the write-to-memory -worked-.

I still suspect Autostar-to-scope communications, if the motor-type
interogation was going sideways, you'd never see a blatant display
about it.

There is also -another- memory in the Autostar...
AH!   When you power-up again after a hang-up, does it -remember-
the Date you entered the time before?  (the Time will always powerup
to 8pm)
If the date -is- retained, that's a vote for the parameter memory
working properly.  If it keeps kicking back to 1-jan-(whenever),
it's a vote for parameter memory failure.

So, there's more things to try...

good luck
And more from Dick:
HOLD THE PRESSES!!!!\  Don't reload (yet)


Oh: the -first- magic key combo is the hold-enter-and-scroll-down
keys when applying power.

This doesn't do a -reset-, but does put you in Download mode
for the Updater to play with.
Since a lot of your functionality .....

WAIT!  ... i wonder if your display brightness/contrast is simply
totally -blank-!!!

After entering the Daylight, the display drops from "full ON"
to the contrast and brightness dictated by personal choice.

Expect another message in a few moments...

(it could be working, you just can't -see- it)
Mike here: Good catch. Could be; and it would be hard to see if there was a lot of ambient light at the observing location.

And this:

From: (Richard Seymour)
Let's assume the thing is -working-, and that you just can't 
-see- it.

Try (among other things) simply tilting the Autsotar every which-way,
with a moderate-intensity light source bouncing off the screen
and reflecting towards you.
Can you see slightly darker pixels on the screen?
Maybe saying "Align / Easy" or "State / California"?

If so, we're half-way there...
(a) Press the [mode] key a few times. (4? 6?)
(b) Press scroll UP once
(c) press [enter] once
(d) press scroll UP once
(e) press [enter] twice

If the system is -working-, that should walk you to the Reset 
 function (see below) and the Autostar should restart as if you'd
powered down... but the display brightness/contrast will have been
reset to "normal".

(a) lifts you to: "Select / Object"
(b) scrolls you to:  "Select / Setup"
(c) enters Setup, display now says: "Setup / Align"
(d) scrolls to:  "Setup / Reset"
(e) selects Reset function, performs Reset.

give that a shot... (this is -not- the "too complex" i was talking

And some more info:
From: (Pierre Cote)
Let me address the different suggestions one at a time.

1. Corrupted download ROM:
NO, because I tried a total of THREE different versions (2.2Et, 2.4Ea
and 2.5Ea). I get the exact same problem with each version.

2. Communication problem . I am trying the SAFE mode restart, then
downloading with verify ON. results in about an hour.
NOTE: From any version, I can still download IF I don't answer the
daylight question.

3. The entire Autostar - Scope WAS functioning before the download. I
think this means the communication between the Autostar and the scope is

When it asks about daylight and I press Enter (or Mode), the display
does not change, the serial link no longer works. The display does not
change means I can still read it. The date IS preserved.
In this "hung" state, the arrow keys control the scope, but the digits
(1-9) no longer change the speed of slewing.
Therefore, the problem is NOT that the unit is working and I can't see
it (I think).

Thank you for all the help.

All this leads me to look into Knitting or some other non-technical
hobby. Sad, because I also have the Digi-T for my Nikon Coolpix 5000 and
I was looking forward to some interesting pictures. I really like the
Astrostar and all its features, and am not that interested in the
Celestron Nexstar line.

The latest, safe, download did NOT work: The same problem persists.

One question here concerning my ETX105EC and ist ra-backlash and
adjusting it via the ra-percentage from autostar:

.just after changing directions the picture jumps a bit into the other
.after this, my ra-axis almost doesn't react using slower speeds (1-5)
1=nearly endless to 5=about 5 sec's
.if i release the autostarbutton the picture seems to move a bit further
than wanted

Reading your site I found out, that I'm not the only one having that
problem; But I just can't get that fixed. Played a lot now with that
haven't been into the base yet (scope is new). DEC has only the
picterjump-problem; other reactions are fine.

I realy tried to make everything right. Any suggestions ? I find some

a bit confusing ... Training, setting percentage, training (somehow
loosley described). Maybe thats the Problem.

The other thing is, that I upgraded AS-Version 22Gt to 25Ea , and that
seems to started that all, but I cannot tell for sure, I didn't
check/realised those symptoms bevore.

Mike here: Ah ha! The magic words you said were that you updated the Autostar and then the problem started. ALWAYS reTRAIN the drives from the Setup-->Telescope-->Train menu item after installing an Autostar update. Don't forget to do both the Altitude and Azimuth axis. Normally that is sufficient. But if the "rubberbanding" is still present then RECALIBRATE, RESET, and reTRAIN. (For those new to the Autostar, "rubberbanding" is the term we use to describe the effect of having the Autostar "center" a GOTO object but not quite in the center of the eyepiece field of view, so you slew the ETX to better center the object, and then the Autostar moves it back to where it thought "center" was.) And more:
I am realy pleased, that your replies are so fast ... Some more info now
I actualy opened my ETX105EC today (base only), after I recieved your
mail: The gear is coverd with green grease (which doesnt seem to affect
it anyway). ETX125 is printed on the platine *lol*; I wonder if setting
the autostar to ETX125 will make any difference for my problem ? I had
the autostar attached and watched the gears while modifying the
ra-percentage; setting the ra-percentage, adjusts for a certain amount
of time, the gear will "tighten" itself,  just after changing the
direction (pressing the button only once starts the prozess already).
Well that is a nice feature and should work (logicaly), but it seems,
that beeing able to adjust for 99% (about 10 seconds with speed 5) is
not enough; At least with my telescope. Even the enginespeed seems to
slow. -> With slower speeds I have to wait for the gear tightening, but
it is not tigtening enough. I stil have to wait another 5 secs (Button
pressed). Until the ra actualy moves in the desired direction. So much
for the wormgear, which apart from the above, reacts in a reasonable
time with nearly any speed, it seems that the wormwheel is the one that
hesitates the movement as well. I tried to find a nut to adjust
(simmilar to what Jordan Blessing described), but the nut used in the
ETX105 cannot be tightened using a standard nut-tool (ist not hexagonal,
ist round)

Very complicatetd for me and my vocabulary, but I hope that I explained
everything with the right words.

Any sugestions for me Mike ? I'am just about to say: "Hey, look what a
nice telescope the ETX could have been".

I keep you updated ...
And from our hardware expert:
From: (Clay Sherrod)
This sounds very much as if the worm gear is torqued entirely too tight
on the bracket and the nut that he is referring to is indeed needing to
be BACKED OFF, not tightened.  This is "jump backlash" caused by the
torque compressing the applied force and the gears responding by jumping
backwards momentarily and then hesitating while they resume the
appropriate direction.

This is something that the user should NOT attempt to fix; I would say
that a call to Meade is in order....this really has nothing to do with
the firmware loaded.  It is entirely a mechanical issue, provided that
he HAS retrained carefully.  The grease has nothing to do with the
problem, although some of it should be cleaned away to prevent it from
getting up into the encoder assembly.


Subject:	Upgrading Autostar firmware comment
Sent:	Saturday, May 4, 2002 13:33:44
From: (David Jung)
I got an ETX125 several years ago and due to some bouts with cancer
hadn't really used it, but plan to get started now.  I finally got a
#505 cable (a clone cable off eBay for $1 plus shipping) and downloaded
the ASU software and latest rom file from Meade.

Absolutely no joy.  The ASU program wouldn't automatically find the
Autostar--it would locate it after a com port scan.  Attempts to update
the Autostar software ended with a message to check the cable and
restart. Attempts to "retrieve" from the Autostar caused the ASU program
to crash.  I figured my cheap cable was the problem even though it
looked fine, but decided to try the "Safe-Loader" option before giving
up.  Loading started immediately and completed fine.   The only goofy
thing after reinitialization of the Autostar was the brightness and
contrast settings of the LCD display were way off causing part of the
display to be unreadable...easily corrected.

I guess the tip/comment is, if you have an older firmware in your
Autostar (mine was 1.3), then don't bother trying the "upgrade", just do
the safe-load method.

Sent:	Friday, May 3, 2002 8:24:49
From: (Me)
I set up my ETX-125 with Autostar last night, and had an unusual problem
occur.  First of all I was powering it through the auto-adapter; set up
went well for alignment ( I run Alt/Az configuration).  However the
Autostar started acting peculiar right away.  It lost power one
time---with the power light on the base still lit.  Moving it around, it
came back on.  So I had to re-align, and reset.  Second time, the
background on the autostar went "bright" and it froze up.  Odd, I
thought.  My first inclination was to see if the cable was loose, or
gaining only intermittent contact.  Checking this out, I saw that it was
secured tightly.  So I gave up, when it went "off" for the third time.

Also one time, I got the "drive motor fault" error!  So I unclamped the
scope and reset it, with even less tension on the clamps.

The temp was in the 40's, so I assume it was not acting up because it
was cold....or could I be wrong?  This morning I plugged the
handcontroller in, and it seemed to work fine---this time being powered
through a dc converter in the house.  I rechecked it with the Autostar,
and it seemed to work fine.  No problems, and I attempted to move, flex
and play with the Autostar's cord to see if the problem would reoccur. 
All to no avail.  I am stumped.

It's nice to see it was working fine today, in controlled conditions,
but if it doesn't work in the field, it's not going to be of much use! 
I had the Supercharge and update done to my scope last fall, and I have
never encountered this before, even in the dead of winter with temps in
the 0's!  Now would you recommend replacing the Autostar cord, or should
I have the Autostar looked at?  I don't know!  Any help is appreciated! 
Can I even buy a replacement cord?  I sure don't want to replace the
whole unit, unless I absolutely have to!

Thanks in advance for any advice or insight!
Mike here: I doubt that temperature was the culprit. Could have just been a power line glitch or perhaps moisture (although I don't recall any dew-related problems with the Autostar). You might need to reTRAIN the drives but since it worked fine indoors I wouldn't worry too much about it.

Mike here: Personally I just use the 26mm eyepiece on Polaris when training the drives. I don't have any good terrestrial objects so Polaris works for me. However, for really precise training you want a stationary object and always get it back into the exact same location in the eyepiece field of view. Using a high magnification reduces the amount of error in this location.

Mike here: You only TRAIN when using the Autostar, not the standard handcontroller. The intention is to use a stationary target, hence Meade's recommendation to use a terrestrial object. You can use Polaris if no other source is available as it moves very little during the TRAINing operation.


Thanks Mike, I must have been having a brain cramp or I would have

This is to Mike for general posting, and to Dick for the "professional"

Aside from having problems (described below) in updating the Autostar,
I've noticed that for the 2.4Ea and 2.5Ea versions that were recently
released, my "percentage complete" indicator at the bottom left of the
ASU (both 3.5 and 3.5.1) have never reached 100% -- I think they've
ended at about 86% in both cases. Everything about the Autostar SEEMS to
be fine -- all menu items appear to work as expected, tours, satellites,
comets, asteroids, etc. appear to be there, no glitches in the display
-- all hunky-dory (or so I believe). Dick, can you (or anyone else)
confirm (or deny) this, or else explain it? Is the "86% complete" really
100% -- is that last 14% data that doesn't need to be updated (user
sites, user info, whatever) or is not affected by the update?

As for the problems encountered in updating the Autostar, I've already
posted my frustrations earlier on this site. Although the new ASU is a
joy to use as far as its GUI is concerned and it is so much more
"user-friendly" than the earlier updaters, I still have increasing
trouble in performing a successful download to the handbox before I get
a handshake problem or a time-out error. I'm running on a Mac G4 450/DP,
Virtual PC, Keyspan adapter -- you know the stuff. ASU 2.4 (the last
incarnation of Meade's updater before it got nice and pretty) at least
allowed me to finish a complete update to the handbox every time -- the
newer ASU 3.x versions have not. When I try for a "download" FROM the
handbox into the ASU application, all goes well each time. But in the
other direction, sending TO the handbox, it rarely, if ever, has worked.
Dick already suggested that I try changing the READWAIT value from 60
(milliseconds) to 120 -- that didn't work. In trying to experiment with
that value, I've "upped" it all the way to 20 and "downed" it all the
way to 240 (thinking in reverse, here), but to no avail. -- same
handshake loss or timing error. I've also had the "percent complete"
dialog show about 3% or 5% or 7% and up pops a dialog box saying
(paraphrasing) "The update to the Autostar handbox has been successful"
-- not with 7% complete it ain't!!

>For the last two updates, I have had to physically lug my scope,
Autostar, cables, and AC power adapter to my next door neighbor's and
use his Gateway running Windows to get a successful upload (and on the
first attempt) -- how embarrassing  :-(

In that puppy, the percentage they're talking about is

If [update], i would expect the above to leave you in "only Safe Load
works" mode.  But if User Bodies, (and you don't have many/any) then
7% is a believeable number.  I've sent 0% (zero) at times, just to
(try to) confuse it.

Hi, Dick --
sorry, sorry, sorry -- you engineers are all alike  :-)
How's about a nice, firm "maybe"?

'm a -little- unclear... are you talking the [update now] button
(in which case the answer is "yes", and it pops up a little 
message box saying "transfer successful" [ok]  or something
reasonably close to that...)

YES, when performing an Update Now on the Autostar FIRMWARE -- and I will get a "Transfer successful" [ok] message box after only a small percentage has been transferred (maybe 5 or 7% -- something small like that) -- then I assume I'm getting the timeout/handshake error...

Or are you talking about the [send data to handbox] button,
in which case the answer is "not necessaily"

NO (see above) -- this all relates to the FIRMWARE update, NOT sending data (i.e., user objects, comets, etc) to the handbox

In that puppy, the percentage they're talking about is
-sometimes- the -possible- percentage... of the 64kb space
in the 497 autostar.  This is especially true when you're
doing a [retrieve data] operation,... the updater doesn't
know how much stuff you -have- in the autostar, so it's merely
showing percentage-of-possible, not percentage of truth.

This chunk:

sure sounds like you're talking about the User Bodies, not the
firmware  ([update now]) itself.

(guess I confused you here, kinda mixed apples and oranges and came up with grapefruit juice) -- YES, in THIS case I'm talking about GETing the User Bodies -- I can easily GET the user bodies each time I try -- it's the UPDATE NOW process that doesn't work (and as a new piece of FYI -- I can successfully SEND DATA to the handbox with no problem -- i.e., tours, comets, asteroids, etc. -- it's the UPDATE of the firmware that's the problem).

> I've also had the "percent complete" dialog show about 3% or 5%
> or 7% and up pops a dialog box saying (paraphrasing) "The update to

again, see above

**WHICH BUTTON DID YOU PRESS???**  [update] or [send data]?
If [update], i would expect the above to leave you in "only Safe Load
works" mode.  But if User Bodies, (and you don't have many/any) then
7% is a believeable number.  I've sent 0% (zero) at times, just to
(try to) confuse it.

NO (to the end of your thought -- i.e., User Bodies -- i.e. Send Data button -- NO, I am not talking about User Bodies) -- YES to the Update Now button -- I am talking about UPDATING the Autostar FIRMWARE -- the percentage will show about 7% complete and the message box will come up saying "Transfer Successful" (and, of course it isn't)...

but my question was, when I DO take the whole thing over to the neighbor's and I DO get a successful FIRMWARE update, the "percentage complete" showing at the bottom has been about 86% (both for version 2.4Ea and 2.5Ea) -- sooooo, is that number correct, or should it show 100%?

Three ideas: (a) build a power-the-autostar small unit as detailed on
a few of Mike's pages (b) buy a used PC ($50 at Goodwill?) so you can
do this in the closet (c) umm.. dang, i forgot the third...

re: (a) -- thought of that, though that doesn't solve the actual upload problem described, only keeps me from getting a hernia (glad the -90EC is so light!!)  (b) ix-nay on the PC -- I have enough complications in my life -- I don't want to add Bill Gates to the brew -- I'm confused enough trying to use Virtual PC half the time -- I'm a tried and true Mac diehard and (c) well, I can't think of a (c)...
have fun (now that it's loaded)
that I CAN do!!! -- at least until the NEXT update  :-)

Do you leave you car at the mechanic's saying "it's got a noise",
only to get it back with (a) the same noise (b) the squeaky
 wheelcover removed, (c) a LARGE bill (90% "diagnosis")?

Ok... so it's the UPDATE operation.  Got that.

Ya know? it should -say- "Check Connection" if it thinks it can't talk
to the Autostar (lemme rephrase that: on a WinTel box, it does.)
So you're facing a multifaceted bug: (a) it doesn't successfully 
Update (b) it doesn't know it (c) it lies about the outcome.

Time for (yet another) note to Meade...

I have a few old PCs (and bigger) of various brands and operating
systems lying around both home and work.. which are only turned on to
perform -one- task for which they're the "best answer".  Then they're
turned off for another long period (i power up my RadioShack Color
Computer about once per four years... but when i do, it's because 
i need it to run programs written in 1984.).  
Imagine the joy of a clunky $50 laptop with crummy screen.
Usually it's tossed in a corner with "I wish i was a Mac!" painted
on the cover... use it as a trivet under hot dishes, as a speaker
stand, cover for aquarium or support for the cat's litter box..
But once every few months, you scrape the kitty litter off, and
fire it up... stuff in a PC floppy which you wrote with the Mac
holding the new firmware... have a PC-conversant friend put the
ASU into the "Startup folder" so it fires up at boot time too...
do the download... then turn it off.
No Virtual PC infiltrating/infecting your Mac, fewer frustrations
due to house-of-cards emulations stacked 50-deep.
Then the laptop can go back to its proper place, and the cat
can resume with its business....

have fun... until 2.6Ea comes out...

Mike wasn't clear:  YES.  If you download the new firmware, you get
30,000 objects.

displays the full firmware version number.
As Mike said: if it's below 21(anything) it's 14,000
If it's 21(anything) to 22eR, it's 30,000, but with a completely
weird set of SAO stars (programming error on MEade's part)
If it's 22eT or newer, the 30,000 objects include the 16,000 stars
from the SAO catalog down to and including magnitude 7.0

The 22eR stars are described at
The 23Eb stars are at:

That's (almost) a new one on me...

There -have- been issues in the past with focuser interactions
with the Autsotar, but i don't remember this one.

Something you can try: unplug the focuser.
Then power up, align, etc.
When you -want- to focus, plug it in.
When you don't -need- the focuser, unplug it.
(of course, the other alternative is to simply use the focuser's
hand unit, so it's totally separate from the Autostar.

If it's not electricalyl connected to the AUX port, there should be
no way that it can affect your scope's performance.
The "weight" of the beastie sure doesn't affect my ETX90.

good luck
