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 checks.

Subject: [ap-gto] My AP1100 CP4 died (I think ..., need confirmation)

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?

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?

Hi Eric,

That worked Ray. Thanks.
There were 4 <HorizonLimit> sections and multiple <PointingModel>, <Initialize>, and other sections. I assume
that shouldn't be the case?
Correct, there should not be multiple sections with the same tag. The settings file was corrupted.

Re: Question: How do I safety replace the CW shaft adapter (got it off, grease?)

Don Anderson
 

Hello Cytan
I wouldn't bother putting anything on the threads. If you are worried about the CW shaft getting stuck to the adaptor, use some anti seize compound and put it on the shoulder of the shaft and/or the mating surface of the adaptor. Better yet, use one of APs Delrin washers and you will never have a problem. If you are worried about wearing out the threads (could take 50yrs to do that) you could put a small amount of 3 in One oil on the threads. If you want an anti seize compound, Christopher has recommended a god one. Also, if you are near a marine store, you can get anti seize compound at any marine or automotive supply store.
My advice is worth as much as Christopher's!Emoji

I suppose that using both GPS devices would allow me to use one of them for time sync and the other for APCC location data (since two pieces of software cannot connect to one GPS at the same time).
There's a way to mirror COM ports on Windows, although it's a little janky and a bit manual.

If you go to the com0com project on Sourceforge:

https://sourceforge.net/projects/com0com/files/com0com/3.0.0.0/

and download the hub2com and com0com software, there's a ReadMe in the hub2com zip file that details how to set up a COM port mirror. An example is given using a GPS device. This is handy for read-only applications such as this.

So, if you're really stuck between a rock and hard place and need something that lets you read the GPS device via COM port with 2 (or more) different apps, then this might get you out of those woods.
