Yes, initially it lite red.  As soon as I directed east, the yellow light immediately went on and the mount would not move in the east direction. After restarting, the mount would move west, but not east.  Directing east caused the light to turn yellow and motor stall.

Do you remember whether your CP4 LED lit up?

Anyway, it was a very weird night. After powering up, with the CP4 LED lit up, I wasn't able to talk to the CP4 with USB. I changed USB cables and used my backup laptop and both wasn't able to talk to the CP4. But I was able to talk to it via TCPIP. In APCC, I can move the mount in RA but not DEC. That's when the stall error popped up.

After taking it back indoors, the CP4 LED no longer lights up :(

The "Motor Stall" warning will occur when unsafe limits are exceeded. This is not a warning that something is wrong with the motor or electronics, it is simply telling you that the software has turned off the power to the motors to prevent your scope from being damaged. At this time we use the same error code for all situations where the motor power has been turned off. It probably could be changed to indicate not "motor stall" but "motor power deactivated".  However, we have many other software challenges right now and this one will have to wait a bit. Be assured that nothing bad has happened to your electronics or the motors.

Hi Rolando,
   I'll call George on Tuesday.

   In case, he does read posts on the long weekend, I did the following this morning:

(1) Checked that the PS is spitting out 13.8V.
(2) When connected the PS to the AP1100 CP4, the CP4 LED does not light. NO other cables other than the power cable is connected.
(3) I connected the motor and encoder cables (+ the PS is connected).
     (a) LED on CP4 remains unlit.
     (b) The encoder LEDs are lit (green and blue).
     (c) I checked that the pins of the keypad socket and they do show 13.8V. 
(4) I opened the motor plug of the cable to see if all the wires are soldered properly. They are.

Aside: I took the PS and powered my Mach1GTO CP4 with no other cables connected and I see the CP4 LED lit red.

I hope that's enough info to start the debugging process.

Hi guys,
   I think my AP1100 CP4 died this evening. The first symptom was that my CP4 wasn't recognized with the USB connection. But I could talk to it via TCPIP (my backup). But APCC couldn't move the DEC. It gave the error message in APCC shown in the attachment. I thought it could be the latest Win update, USB port, USB cable, bad motor cable, Power supply etc. I checked that the CP4 module LED was lit red (and it was). I power cycled the CP4 a few times to be sure that it wasn't hung up on something. That didn't fix the problem.

  After two hours of monkeying around, I gave up and brought everything back inside. Since I have a Mach1GTO with its CP4, I used the same USB cable, power supply and computer to verify whether any of them were the problem. These tests showed that the same computer, USB cable and PS worked with my Mach1GTO CP4.

  So after the Mach1GTO tests, I wanted to test the AP1100 CP4 again. But this time the LED didn't light up.

  Well, I guess the CP4 must have died a slow painful death :(  Is there anything else I should or can test before I ask for an RMA to ship it back to AstroPhysics for repair?

Re: My AP1100 CP4 died (I think ..., need confirmation)

fwiw.  One time I snagged a Dec cable on the AP1200.   And got a yellow light (CP3).  
After unsnarling the cable the yellow light persisted.  Turned out a couple wires had become “unsoldered” side the Dec motor connector on the cable side.    I soldered them back up and the mount then worked.  
Then I bought spare cables. 

I presume you do not have spare 1100 cables to test with.

Is it possible the RA or Dec cable wiring has become loose inside the connector?

Re: APCC compatibility with ASCOM 6.5 SP1 (?)

Ray Gralak
 

There wasn't a "compatibility problem" between APCC and ASCOM. There was a severe bug in the ASCOM platform 6.5 that caused an issue translating between J2000.0 and local apparent RA/Dec coordinate systems. This was fixed in ASCOM Platform 6.5SP1.

I know that there have been reports (a fair time ago) of problems with APCC and ASCOM 6.5. As a result, I am
WAY behind in both APCC updates and ASCOM (I am on 6.4) updates, as I did not want to introduce problems in
a simple and working system.

OTOH, I now see that ASCOM 6.5 SP1 is the new standard release of that platform. Does this fix issues with
APCC compatibility? Can I go ahead and update my system (both ASCOM and APCC)?

I'd rather err on the side of caution, but I also know that staying too far behind current releases is not a good idea,
so... what's the verdict?
