PTC-140 and RMC-190 RS-232 Connection
Q:Does the RMC-190 Function with the PTC-140 Cameras?
A: Yes they work with a standard RS-232 Din Connector but the baud rate on controller needs to match Camera.
Baud Rate 38400 would be the standard on the PTC-140 unless another baud rate is desired.
Below is the image of the cables that is needed you will first need the CB-57 to connect from the Controller and also CB-55 which will connect to the camera.
This way you can extend the length of your connection and allow you to control your camera from further away.
