Hi sctom1,
?
The hand controller cable is actually an RS232 (serial) communications cable. If you use it at 9600 baud, serial cable can be fairly long, 15m or longer. A lot? depends on cable properties. Using Ethernet and the virtual HC is probably a more reliable and easier way to control your Gemini, as Chip suggests, but with a 25ft cable, I suspect you should be able to get your HC working in the warm room.

What type of cable is between the hand box and the Gemini II and what is the maximum length I can go? My observatory is being planned with a warm room separated from the scope room and I may need up to 25 feet of cable so I don¡¯t have to walk out to the mount to do the start up every time with the hand box. ?The hand box will be on a desk beside my PC running NINA. I will leave the Gemini turned on, but shut off power to it when not used, so no other need to go to the mount at startup or shutdown. ?Unless this will cause issues with the Gemini.?
FWIW, 20 feet of USB 3.0 from PC to Pegasus UPBv3 works fine. Will try 25 feet soon.
Many thanks
