Re: APCC PRO and Virtual Ports

Ray Gralak

Hi Jack,

My only suggestion is that you can try increasing the timeout in the AP V2 driver. APCC uses a third-party component for the virtual ports in APCC. The component is exactly the same for both APCC Standard and Pro, and there should be no reason that higher virtual COM port numbers would act differently than lower port numbers.

I modified the sample horizon file you sent to me and now have the horizon for my location input into APCC PRO.
But now I have a new issue.

I have been using APCC Standard for years to control my AP1600 using SkyTools PRO V3 and now SkyTools V4
Imaging. I have the mount connected to the computer using the Serial/USB connection on COM3.
I have two Virtual Ports created - COM6 and COM 12. I have been connecting SkyTools to the mount using
ASCOM V2 Telescope Driver - v5.30.10 on COM12 and occasionally I get a lost communication error message,
SkyTools shuts down, and I then have to restart SkyTools and reconnect it. I thought that maybe since I was on
COM12, that was the problem. So I created COM31, went into the ACSOM V2 Telescope Driver setup for
SkyTools, changed the COM port from 12 to 31, checked the port and it was found. But when I went to connect
SkyTools to the mount, a connection could not be established.
I eventually went back to COM12 and it connected right away.

Any idea what the problem could be? I would like to use the higher COM numbers if possible.

Yours truly,
