TABLE 2: RECEIVER LED DIAGNOSTIC INDICATORS
TABLE 1: TRANSMITTER LED DIAGNOSTIC INDICATORS
LED Name
Color
Indicates/
Corrective Action
Green
Sufficient optical power received.
No action required.
LEVEL/
LOSS
Red
Optical power not being received. Fiber open or transmitter or receiver inoperative.
Check fiber loss, connectors, and splices (if any). On two-fiber units, verify TX port
connects to RX port.
Green
Video coax input to link is good. (Note that even a totally black screen is a valid
video signal.)
No action required.
VIDEO IN
Red
Video coax input to link is not good.
Check the camera and the coax into the link.
Green
Indicates PTZ command transmission (greater than 250 mV).
No action required.
CMND OUT
Off
No activity or command being transmitted is less than 250 mV.
Green
Indicates response from camera is greater than 250 mV.
No action required
.
RESP IN
Off
No response from camera or signal is less than 250 mV. This may indicate a
problem with the camera. This function is not available in all systems.
Green
Indicates transmission of Genlock Synchronization signals greater than 2 volts,
where applicable.
SYNC OUT
Off
No Genlock Synchronization signal received or level is less than 2 volts.
