Ray, I checked the COM port, and use the same one as in the GPSinfo program. The PC has two physical COM ports and one USB-to-Serial port (for the GPS) so it's hard to get it wrong.

Ray, I have the 1100 GTO with encoders. I only posted to this Mach 2 thread because it already mentioned the issue.

Hi Eric, The subject says "mach2" so I thought you meant mach2 even though you wrote "1100". You can still ignore the error. That command should not be sent, but I'll have to debug the issue. -Ray

Rolando, George, Is there a version of the CP4 firmware that's newer than P01-14 that knows about the :m# command?

Good point, Brian! If you are looking for ASCOM 6.4 SP1, here is the download link: https://github.com/ASCOMInitiative/ASCOMPlatform/releases/download/Build_2695/ASCOMPlatform64.exe -Ray

Just to clarify I think Ray posted the 6.5SP1 beta (not the prior 6.4 version), but the SP1 beta also works with APCC -- Brian Brian Valente portfolio brianvalentephotography.com

I know this topic has been discussed but I was not able to find the information I need so requesting again. I just added the absolute encoders to my 1100GTO and setup APCC Pro. I have ASOM platform

Eric, The logic for the GPS code has not changed in a long time in APCC, but maybe something in the .Net Framework has changed. BTW, I assume you checked that the GPS COM port is correct? To be

Ray, I tried that and it didn't help. I even tried a different version of APCC and it didn't help.

Thanks Ray...btw...that delay you put into APPM for dome slewing is still working like a charm for the APPM run :)

Hi Tony, It doesn't have to be the absolute best focus, but having good quality focus will provide more accurate results. -Ray Gralak Author of PEMPro Author of APCC (Astro-Physics Command Center):

I started an APPM run and realized I didn't get the sharpest focus...its not bad but it could be a bit better. Will that be detrimental? Should I just stop the APPM run and focus as best as possible

There could be some garbage characters in the GPS's virtual port. Make sure nothing is connected to the port by disconnecting your GPS Utility and restarting APCC. -Ray Gralak Author of

Hi Eric, It sounds like you might not have the latest firmware. You will need to check with A-P to get updated firmware. Until you do that, you can ignore these timeout messages. The firmware you

I have a BU-353S4 GPS that used to work. Now when I try to connect to it, it connects, then after about 5 seconds it disconnects with the following error: Closing GPS Connection. UpdateLocation:

I just upgraded to 1.8.7.1 on my 1100 mount, and am getting the ":m3# The operation has timed out" error. Is there a version of APCC that fixes this.

Hello Ernie, You appear to have really did spent some time trying to troubleshoot Sky Safari. Impressive that you found a work around. I originally was using Sky Safari 6 Plus and WiFi connection

Thanks Ernie, I’ll have to give this a shot. May be a moot point soon once the keypads ship. I appreciate either way. Thanks, Haydn

Hi Ray. I will will give the ASCOM 6.5 SP1 Beta a try. Thanks for the update. Andrew J
