Re: Defective CP4 control box

HI Joe,

WiFi problems could indicate interference from nearby sources.

As for ASCOM, try looking at COM ports in device manager. When you plug the mount's USB cable into your computer a COM port should be created. That's the port to which you need to configure APCC to connect.

Subject: [ap-gto] Defective CP4 control box

After several nights of failed troubleshooting I have contended that my CP4 control box is defective. My Keypad
controller was not working with it, the East and West RA slew would always stick and stall. AP received it last
Wednesday but nobody has contacted me about it since. Now I believe it may have been the CP4 all along that was
the problem is it has many issues. I have tried to run the 1100 with SkySafari and Luminos and both were very
problematic. The WIFI connection would constantly drop connections. It would require cycling the mount's power
supply battery to make the WIFI appear again only to lose the connection after a few minutes. The centering slew
commands are very unresponsive on both apps and no less that four times I have to yank the power cable in a panic
because of runaway slews that could not be stopped. ASCOM does not work at all on USB. I tried literally ever COM
port available only to get mount not found error messages. So can someone at A stro-Physics please contact me
ASAP on how to rectify this problem.
