Control Protocol And Baud Rate - Vidia PTZ User Manual

5.4
Control protocol and baud rate must be set correctly to the camera in order to
establish proper communication between the camera and control device.
Be sure that the same protocol and baud rate are selected in control device, too.
Presently 2 types of protocol and 3 levels of baud rate are provided by this speed
dome, through an 8-bit DIP switch labeled DS1.
DS 1
First, installer needs to choose a communication protocol with bit number 3, 4
and 5. Watch that the same protocol is chosen for speed dome and controller.
The following table shows the three protocols provided in this speed dome.
Check what are available in the controller before choosing the protocol.
Bit 1 and 2 are for baud rate setup. Same baud rate must be set up for the
speed dome and control device, or communication for control will fail.
