DLC170DA Front Panel LEDs
LED Function Color Description
OK
DLC170DA
Module
Status
OFF If power is applied to the system, an internal fault with the DLC170DA may exist
n Green Normal operation
n Yellow
RX status LED may provide fault information. If no other status LEDs indicate a minor alarm, then a
temperature alarm is indicated
n Red
Major alarm exists and requires immediate attention. TX, RX, or VIDEO status LEDs may provide more
information on the fault. The alarm may also be the result of an internal error
EMS
DigiLink Manager
System
Status
OFF
The DLC170DA module is in local mode and its configuration is controlled by the onboard
configuration switches
n Green
The DLC170DA module is in remote mode and the configuration has been set by the EMS. When in remote
mode, the actual configuration of the module will likely not match the settings of the configuration
switches and changing the configuration switches will have no effect on the module operation.
TX
Transmitter
Status
OFF Transmitter is disabled. The DLC170DA is not being used to repeat the received optical signal
n Green
Normal operation (input signal is present). The DLC170DA is being used to repeat the received optical
signal
n Yellow
The DLC170DA cannot detect an optical video input signal to repeat and is transmitting the non-video
keep-alive standby signal
 Red (1) Major alarm condition exists because no optical SFP is installed or an optical SFP TX fault exists
RX
Receiver
Status
OFF Video input from the backplane (not the SFP) selected
n Normal operation (optical video signal is detected)
n Yellow Non-video keep-alive signal is being received
 Yellow Receive optical power is high
 Red (1) Major alarm condition exists because of low optical receive power or because no SFP is installed
Video
Video
Signal
Status
OFF No video input is detected
n Green Video input detected
n Yellow
ASI signal present on the BNC output; the output is selected for SDI and the received digital video signal is
DVB-ASI
n Red Input video is outside the ±100 ppm range, or non-SDI video signal in analog mode

Status
OFF Analog audio de-embedding is disabled (SW2, switch S1is OFF and/or SW2, switch S2 is OFF)
n Green Analog audio de-embedding is enabled and a valid signal is present
n Yellow Analog audio de-embedding is enabled and errors are detected in the embedded audio signals
n Red Analog audio de-embedding is enabled and no audio program is detected in the selected group

Signal
Status
OFF AES audio de-embedding is disabled (SW2, switch S1 is OFF and/or SW2, switch S2 is ON)
n Green AES audio de-embedding is enabled and a valid signal is present
n Yellow AES audio de-embedding is enabled and errors are detected in the embedded audio signals
n Red AES audio de-embedding is enabled and no audio program is detected in the selected group
1. Loss of video will be a major alarm if the “Video Loss Alarm” is enabled (SW2, switch S8 is OFF).
