3. PICTURE TOO DARK
Make sure that monitors and other peripheral equipment connected to the video source are set to high
impedance termination since the Transmitter has a built-in 75ohm termination.
4. PICTURE TOO BRIGHT
Make sure the Receiver video output line is terminated with 75ohm.
5. CANNOT CONTROL PTZ
Check the twisted cable + and – are connected correctly.
Check the RS485 PTZ settings in the Transmitter and Receiver are the same as on the PTZ Controller.
6. PTZ CONTROL IS NOT SMOOTH
Check the RS485 twisted cables' connections are good.
If the connection distance between the PTZ Controller and the Receiver is too long, reduce the baud rate on
both the PTZ Controller and on the Shepherd Transmitter and Receiver.
