Which camera settings for Pelco Spectra camera

[jifop 0]

Hi chaps! I'm hoping someone can help me! I have a Pelco Spectra II/III Dome camera currently connected to a pelco system and I'm trying to move it to a Vidor VDR-208 but I can't get the PTZ to work!

 

Does anyone have any ideas?

 

on the current system it is set as;

COMM: 2400,N,8,1

D Address: None

P Address: 1

CM9500 Mode: Off

Protocol: C

 

On the VDR I have tried;

protocol: pelco-d

RS-485: 2400

PTZ ID: 0-3

I have just been and set dipswitches on the camera to 9600, D, 1 but still I have no joy

The Spectra should be configured to 2400/4800/9600 N,8,1 and probably to Pelco "D" protocol, since few DVRs support Pelco "P" protocol (note: later Spectras autosense protocol). The DVR should be set to the same settings. You might want to set address as "1" in "D".

 

Make certain you have things connected properly. Tx+ on the DVR to Rx+ on the Spectra and Tx- on the DVR to Rx- on the Spectra.

Thanks, the DVR is set to 9600, ptz 1, pelco-d but its still not working!

 

As for the wiring doesn't it all go down the coax? In which case how do i check it?

I haven't worked with "up-the-coax" control for years. Few systems use it anymore. Most use RS422/RS485 because "up-the-coax" control tends to be flaky. Are you certain your Vicon DVR can send control signals up the coax? I'm looking at its manual online and don't find any reference to it being able to do so. It just states "PTZ control through RS-485".

 

You would have to run a separate cable for control - typically one pair of a CAT5/CAT6 cable works but you can use almost any twisted-pair, including 18/2, 22/2 shielded or even speaker wire for short runs.

Damn and thank you! You are absolutely right it looks as it the only way to use PTZ is to run another cable out which in this situation is not really doable due to the camera location.

 

I will use the old pelco system and loop out of it into the DVR

 

Thanks
