Check the wiring connections.
If the CX LED does not blink when commands are sent to the receiver, make sure the controller is
working properly. Also check the video coaxial cable between the controller and the VIDEO OUT
connection on the receiver.
An LRD41TLC Test Local Control Module is available from Pelco to test or troubleshoot your
receiver, pan/tilt, and lens functions directly from the receiver.
This lightweight, hand-held keypad tests the up, down, left, and right functions of the pan/tilt, and
the iris open/close, focus near/far, and zoom telephoto/wide functions of the lens.
1. Plug the module into the TLC connector on the front of the receiver. The module can be plugged
in with the receiver’s power turned on.
2. Push the buttons on the keypad to test your equipment. The TLC module can be used without
disconnecting the receiver from the controller. The TLC module will override any signals from
the controller.
