Subject: updating a 497 Sent: Sunday, February 1, 2009 04:03:38 From: Douglas Hornick (firstname.lastname@example.org) Another fine tip found on your site has got me out of a bind. I installed the Autostar Suite Astronomer Edition that came with my scope and was playing around with the telescope pull down and found update Autostar. I chose the Upgrade Autostar Software Now button and selected the radio button to find software on the internet. It found version 59Ef which I thought strange since that was not mentioned in Meade's download section. Uploading this firmware scrambled my 497. Luckily you had helped a person named Jim with a similar situation and I pressed the enter and scroll down buttons, then turned on the scope. I then uploaded the most recent version on Meade's site 43Eg and my scope's back in business. Thanks again Mike. DougMike here: Wow. Wonder why it got such a strange update??? Glad you got going again.
And from our resident AutoStar Expert:
From: richard seymour (email@example.com) Oh, the *** hits the fan... (i was able to duplicate the experience) DO NOT USE ASU TO UPDATE YOUR EXISTING 497 AUTOSTARS!!! Meade has silently introduced a new "497 Autostar" As far as i know, it's only being shipped with the new LX90's. It has a -completely- different processor (Toshiba TMP92CM22FG instead of Motorola/Freescale M68HC11) and memory layout (2MB!), far smaller part count, etc.etc. Totally machine-level firmware incompatible with the older 497's. As far as i know, there's no way to tell them apart -externally-, but the new one arrives bearing v59Ef when you fire it up. v59Ef appears to be a simple "port" of v43Eg to the new platform (i.e. the original higher-level program was compiled with a new target platform). Limited testing by others have shown it to have many of the same bugs as 43Eg, so it's a fairly accurate "port". It should be "plug compatible" with existing telescopes. Since it's a new internal processor, my patch kits will not work with it (yet). One BIG improvement is that they've used gold on the keypad contacts. ASU (as of last week) couldn't handle 59Ef and the -new- Autostar. But i was not aware of it accidently picking -up- 59Ef and trying to cram it into the -old- Autostar, until you sent this note. Investigations have shown a "beta" ASU which appears to work with the ETX-LS, (like you, i can't really tell, since i don't have one) but which does -not- appear to work with the new 497 Autostar. have fun --dickMike here: Thanks Dick! My "fixed" LX90 had 4.4Ea but that was a few months back.
From: richard seymour (firstname.lastname@example.org) They fixed the 59EF problem (on 26th Feb)!!! If you -now- choose [update Autostar] from the ASU, you get 43Eg (not 44Ea... fascinating...)
From: richard seymour (email@example.com) I have not "seen" versions 59E7 and 59Ed, but someone loaned me an Autostar with the current version: 59Ef. 59Ef is also available from Meade's website, so we could analyze it. I am aware of at least one person who updated from 59Ed to 59Ef and saw many of his problems "fixed". The remaining problems i'm -aware- of (meaning: there are more, i'm sure) in 59Ef include: --------- 1) If you have an LX90-gps east of Greenwich, it's confused. 2) The :EQ/:ES so AutostarSuite's remote treebuilding is broken 3) Planet calcs for Saturn/Jupiter etc (4 degree errors!) 4) PEC in motor speed calcs --------------- Andrew Johansen (author of Andrew's PEC Editor) has been putting lots of work into this.. and has managed to patch 59Ef to fix the above. (yesterday... so this is "breaking news") Once we test it a bit more, and batten down -how- to make it into a user-accessible patch kit, we'll certainly post it. If you wish to update to v59Ef now, you have one safe method: (a) download the newest AutostarSuite (200 megabytes) which includes ASU v5.6 which is capable of dealing with the new Autostar. You'll find that at: http://www.meade.com/downloads/
Subject: ASU v5.6 available at Meade's site... Sent: Thursday, June 4, 2009 08:22:32 From: richard seymour (firstname.lastname@example.org) ...but you'd never know it... Although the *page* says it's ASU 5.2 (posted June 2, 2009) the actual -file- you get is AU2ver56.exe In other words: version 5.6, which is compatible with both the old and new 497 Autostars. Page: http://www.meade.com/support/auto.html ASU 5.6: (do a "Save As..." with this link) http://www.meade.com/support/auto/Au2ver56.EXE have fun --dickMike here: There is more discussion about this on the June AutoStar Feedback page.
Subject: New Firmware Sent: Tuesday, July 28, 2009 16:49:35 From: Meade Customer Service Did you know there are two types of #497 Autostar? The newest, designated the #497ep, utilizes an updated chipset. However, in light of the newer, faster, chipset, the #497ep firmware doesn't work with the older #497 Autostar and vice versa. Meade has just released a new firmware version for the #497EP, version 5BE2, which is accessible once you upgrade to the new Autostar Update (ASU) Client. If you have an older version of the Autostar Update (ASU) Client (version 5.1 and earlier) the updater cannot tell the difference between the two controllers. Go to the link below to download and install version 5.6 of the Autostar Update Client Application. This new version of the updater can detect which Autostar controller you have and download the latest version for your Autostar. http://www.meade.com/support/auto/Au2ver56.EXE We would encourage all Autostar users to upgrade to the new client app. Meade Customer Service
