Audiostar Update error
Posted 23 October 2012 - 04:52 PM
The reason for the thread is after installing the Autostar 5 software on my Windows 7 machine and connecting to the rs232 on the Audiostar handbox I had some trouble getting the software to find the HBX. Finally realized that the com port needs to be com 8 or less. Now the problem is the Autostar update software crashes from the menu selection in the Autostar Suite and when ran straight from the Windows Start menu. It displays 2 error screens then upon clicking OK closes the ASU program. I know that the HBX is firmware ver A3S2 and the new version is A3S4 and I would like to update the HBX. Does anyone know how to fix the ASU/Windows 7 crashing problem?
Ps. I just talked with Carlos at Meade about 20 minutes ago. He indicated he would get back after he had some time to research the problem.

AU2: An invalid argument was encountered.
Runtime Error! Program: C:\Program...2\Meade\Autostar Updater\ASU2.exe
This application has requeste the runtime to terminate in an unusual way.
Please contact the application's support team for more information.
Still at a loss.

Several people have mentioned this "effect" on Win7,
but i have never heard of a guaranteed reason why ( or a fix. )
I suggest trying StarPatch instead
It is far more robust and faster than Meades ASU,
and allows application of patches dynamically if required.

Just to let you and everyone know I am quite happy with the LX80. It does have a couple issues but for just under $800 it is a good mount for my mixed use I will be using it for. I was quite impressed when it was dead center on Jupiter for 3 or more hours at 150+ magnification.

The firmware is on the Starpatch site, but is currently on a "by request" only release as i am still working on the full patches. ie what he has currently is only tied into the full integration of his StarGPS module to the Audiostar Hbx, hence is only available for purchasers of his GPS lump.
The full patches etc will be out in about a week,
at which time it should go up for general use.
Till then, you can grab the correct rom file from
You will need to rename it as
BuildAU_A3S4.rom for StarPatch to play with it.

The old A3S2 rom appears to have been deleted from their site
( as its superceded, right :-) ). Copies are available from several sources if reqd, but it is as buggy as A3S4 and was never patched past a few simple fixes, so is probably not worth going back to.
I can supply a copy if its really necessary.

Recently, I bought a lx80 mount. I use 8" Lx75 ACF OTA. I upgraded current A3S2 firmware to A3S4. But PHD guide stopped communication with Lx80. I searched web and i couldnt find A3S2 firmaware. There is always A2S4... So, I'll be glad, if you can send me or tell me where i can find AudioStar A3S2 firmware... Thanks...

Im intrigued that PHD no longer works ( appears to work ?? )
I assume you are in GEM mode???
If so, the actual guiding code between S2 and S4 didnt appear to change,
just the tracking and PEC, so i am surprised it doesnt work.
Do you get errors or just no response???
( Or are the problems in DEC ??? If so, turn PEC ON and try again,
as there is a bad bug in A3S4 related to DEC guiding when polar
if you try to do DEC guides before RA guides )
Will dig out a copy of S2 tomorrow my time, but not sure if it will help.

as you mentioned, I'm in GEM mode. I didn't get any error messages. I was using PHD before upgrading. I wonder why its not working now? Cable and other connection elements are operational. I've checked them. Neither PEC on nor off doesnt seem make any difference... Should I turn off DEC guiding for test? btw, I'm using unpatched version of firmware (A3S4)
