Problems with PTZ

Today I installed a GV-VS11 1 channel video server. I'm using it to view and control a Pelco Spectra III SE PTZ. The video works perfectly, however I worked for 4 hours today trying to get the PTZ control to work. I'm using the RS-485 + and - from the video server going to the RX + and - on the PTZ. I've tried the 2400 and 9600 baud rates as well as the Pelco D and P protocols. I'm aware of the addressing issue and tried using the true address of the camera as well as 1 above and below and still nothing. Is there something else here I have not tried? TIA

When you boot the Spectra what shows on the screen? I assume your rebooting after each change? Do you have other cameras on here? Com port is correct?

When I boot the camera the model of the camera, Pelco D address 1, Pelco P address 2 and baud rate shows on the screen. I rebooted the the server several times but not each time I changed the settings. Were accessing the server thru a web browser and I never saw a place to configure a com port.

Attached a couple of screenshots showing some of the relevant config

also another thing- you have to add the protocol you setup in the VS11 to the NVR. So if you have the VS11 setup to use Pelco-D, you need to go to 'add/remove PTZ' in the NVR and add Pelco-D protocol.

They are not using a dvr of any sorts. This is complely web accessed. I did set the server up with the proper protocols, baud rate and address like you showed in the screen shots. The other 2 PTZ's they have on site work perfectly. One of them is an IP unit and the other also goes thru a video sever, however not a Geovision model

Are the other 2 PTZs Pelco Spectra as well?

Are you running daisy chain or star topology? Are there any terminators on the other PTZs?

I assume your using a rs232-485 converter? Do you have am independent ptz keyboard to try?

The other PTZ's are not pelco and there is not a controller joystick for the camera. They tell me that the unit had been working until last server died on them. All I was suppose to do was replace the server and configure it for the PTZ. I'm thinking that the last server was an Earthnet?

have you tried reversing the RS485 polarity?

No that's something that wasn't even on my radar. Guess at this point its worth a try. I won't be back there till next week but will see if it works. Thanks

I have a Spectra Mini and had to reverse it when connecting to USB-to-RS485 converter
