Hi Steve, One other thing to try. Open the cover of your CP4 and push down on the small circuit board to reseat the connections. It is possible that it came loose from the main board. It is highly

It's one big fat zero right now. CP4 LED is off, and after I connect the ethernet cable, nothing blinks on the ethernet port (unlike the first part of last night). I opened up the plug for DEC and

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

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

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

My CP4 was showing similar issues. Turned out to be mount limit warnings. see below from Rolando. Roland Christen 07/31/20 The "Motor Stall" warning will occur when unsafe limits are exceeded.

Make sure that all your cables inside the mount are plugged in. Check the cables going to the motor boxes. Call George during office hours and he will assist you with a couple of simple tests and

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”

Any suggestions as to what to test? I thought I had at least checked that some of the USB cabling, PS, computer were ok with the Mach1. cytan Sent from Yahoo Mail for iPad

It's highly unlikely your CP4 died. You had a motor stall. Possible poor connection of your motor cable. Possible poor connection to your power supply. Rolando

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

Yep. It’s. Helo4@...

I tried to send you some instructions but I don't have your e-mail address. Can you send me an e-mail please? Roland Christen chris1011@...

?

Yes.

We sent you two new cables. Did you receive them and did you put them on your mount? Roland Christen Astro-Physics Inc.

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

Last week I had a RA problem. It had a very loud clicking noise but that was fixed after following Roland‘s advice with switching the cables. But just had another clear night and went to test. And I

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
