HI Folks, Please assist if possible. I set up a GV-800-16 running XP. The GV-800 is working well, no problems. I then attached a GV-NET-I/O card so I could operate one PTZ camera and use the relays. The PTZ is using Pelco D format. I installed the GV-NET-I/O card per the instructions and all the in/outs worked great. I then hooked on the PTZ. I checked the "Hardware" setup in XP and determined the GV-NET-I/O was configured for com 3. In the GV software, in the "I/O DEVICE" page I was instruced to select the "port" and "address" but these buttons are greyed out and I can not set them. If you choose other I/O cards they come alive, but not for this GV-NET-I/O. I ignored them and continued to set the port and address in the other areas of the GV software but the PTZ will not move. Are the instructions for the GV-NET-I/O card wrong. Are these buttons supposed to be greyed out or do I need to re-install the card while the PTZ is connected? Any assistance would be great.
