Subject:	AutoStar Suite v5.0 will not connect to virtual COM ports without error!

From:	Keith Woodard (
I have my AutoStar 497 connected to my laptop's USB port via a RS232
converter adapter; I installed the latest Meade driver to support this
connection. I have Meade's AutoStar Suite v5.0 installed and it works
great while my AutoStar is connected via its 505 cable but not when
emulating a virtual port like COM10. The ASU finds the virtual port with
no problem but the Suite throws an error. Have you observed this issue
under your setup?

Mike here: Not all USB-serial adapters work reliably with the AutoStar and its software. What adapter are you using? See the article "AutoStar and USB" on the Helpful Information: AutoStar Info page for more information. I recommend using a Keyspan model. Also, have you tried one of the other applications for controlling the AutoStar, such as AstroPlanner or Scopedriver?


I just found a fix for using the AutoStar 497 with AutoStar Suite via a
USB connection by setting the telescope protocol for Network. Read this
website for details!

Best Regards,
Mike here: Yes, you need to set up a "network" connection to enable the multiple AutoStar Suite applications to "talk" to the AutoStar via the single RS-232 serial port.

This is a quirk in Autostar Suite version 5 that wasn't in earlier
versions. For some reason, it opens a network port when started which is
one of the same same ports that Netscope opens. The result is a
conflict. You can find a full description in the Autostar Suite archive
for August of this year, near the bottom. There is also an easy
workaround given.

Hope this helps,

Subject:	Netscope.exe

From:	jm dean (
I have just bought a Meade LX75 10" SN. I have spent hours trying to get
it to work with my laptop (Dell Inspiron 6400). I am running Windows XP
and a USB to Serial adapter. When I set it up using the via com port
command it works ok. But I cannot set it up using NetScope.exe. In the
first instance I get "Runtime error 10048 address in use". If I shut
down Autostar Ver 5.0 and run NetScope.exe by itself I get "listening"
in the bottom dialogue box of the NetScope window but it never connects
to an ip address, and the network connection fails if I try Autostar via
network. Any help would be greatly appreciated.

Mike here: There are some articles on the AutoStar Suite network server capability on the Helpful Information: AutoStar Info page, including the article about using it on a Mac. See if anything there helps. Let me know.
Subject:	Telescope Incompatability

From:	Mark Cooper (
Good morning, I hope you are well today. I have spent the best part of
the last 2 days trying to get my ETX 125EC to start working with my
Laptop and the AutoStar Software. I have since been advised that I need
to come back to Meade for a patch for compatibility with Vista?
Can you please help.
PS.      By the way I love the Telescope.
Mike here: I need more info. What software: AutoStar Suite or the AutoStar Update application? Does your computer have a real serial port or are you using a USB-serial adapter? If an adapter, which one? Not all work reliably with the AutoStar (see the article "AutoStar and USB" on the Helpful Information: AutoStar Info page.


Thanks for your quick feedback. I loaded  the Version 5.0 Autostar
Suite. I am using a USB Serial Adaptor. I know the one I have works as I
tested it at the local shop earlier today and with XP software it seemed
to work a treat. Known adaptor numbers are N287 for the connector.
Thanks again.
Mike here: Search the ETX Site for "autostar suite vista" and you will find lots of hits. Check the ones dated in 2008.


ETX Site...?
