Video Server with Pelco D extended commands

[wmorales 0]

Hello,

I am looking for a video server that is able to send Pelco D extended commands to a camera. Particularly absolute Pan/Tilt/Zoom positions shown as the following commands in the Pelco D protocol documentation:

Command 0x4B (75), Set Pan Position

Command 0x4D (77), Set Tilt Position

Command 0x4F (79), Set Zoom Position

 

I have been trying to get this working with an Axis 241S video server with a Pelco D Absolute driver loaded, but have been unable to get it to send the correct commands. Does anyone know of any other video servers that are capable of using Pelco D extended commands? Any assistance would be greatly appreciated.

 

 

 

Also does anyone know what the Zoom Limit used to set the zoom position is, in reference to the camera's lens?
