Having bought a new portable imaging rig based around an ASIAir, I decided to revamp the wiring and software in my observatory. I now have a Raspberry Pi at the mount connected into my home network and connected to the mount via USB using a HitecAstro Eqdir. Using KStars on my obsy Windows 10 PC, I can control the mount via the RPI, so the Eqdir cable seems to be OK.
When I bought the mobile rig, I bought a Polemaster so I thought while I was at it, I might as well polar align the obsy mount. It is awkward to see the monitor from the mount, so I used a Windows 10 laptop. I disconnected the Eqdir from the RPi and plugged it and the Polemaster into the laptop. I tried to connect to the mount using Cartes du Ciel but couldn't. The Eqmod interface (or something) flashes on and then immediately off. I tried using EQASCOM_Run, that does the same but does so continuously and has to be killed (Kill EQASCOM doesn't stop it).
Eventually I gave up and connected to the mount via RPi and used that to do the slewing part of the Polemaster routine, which worked fine.
While trying to get the laptop to connect to the mount, I checked the port to which the PL2303 HitecAstro was assigned and made sure it was correctly set in EQASCOM and I also replaced the driver. I couldn't think of anything else to try.
The only other thing I noticed was that clicking on the Find button in the EQASCOM set up could not find a port.
I'm pretty sure the laptop is the problem but I don't know where. I have the latest ASCOM, EQASCOM and CduC.
Does anyone have any ideas? I've been using EQMOD for years so I am quite embarrassed to ask.
