DLC300 Front Panel LEDs
LED Function Color Description
OK
DLC300
Module
Status
OFF If power is applied to the system, an internal fault may exist
n Green Normal operation
n Yellow A temperature alarm is indicated if the RX LED is not flashing yellow
n Red
The TX or RX LEDs may indicate the cause of the alarm. Loss of video if the video alarm is enabled. Video rate is not
locked. 1 The corresponding signal rate LED will flash red. Possible internal error
EMS
DigiLink Manager
System
Status
OFF The DLC300 module is in local mode and its configuration is controlled by the onboard configuration switches
n Green
The DLC300 module is in remote mode and the configuration has been set by DigiLink Manager. 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’s operation

1. A video rate unlocked condition usually
indicates that the input signal rate is
outside the standard rate requirements.
The input signal rate requirements are as
follows:
- SDI/ASI rates must be 270 Mb/s + 100 ppm
- HD SDI rate must be 1.485 Mb/s or
1.485/1.001 Mb/s + 50 ppm
- 3G SDI rate must be 2.97 Gb/s or 2.97/1.001
Gb/s + 50 ppm
If the signal cannot be held within these
requirements, try setting the DLC300 to
bypass mode
2. When the DLC300 is in repeater mode, the
TX and RX status LEDs are active to represent
the simultaneous receive and transmit
operations occurring
3. Depending on the operating mode of the
DLC300, it processes the signal as follows:
- Transmitter mode—Dithered
- Receiver mode—Undithered
- Repeater mode—The optical transmit
signal is an unmodified (but reclocked)
copy of the optical receive signal. The
electrical BNC output and monitor output
is undithered if SW3-2 is OFF, otherwise these
outputs are dithered.
(The optical transmit signal is an unmodified
copy of optical receive signal). If a DLC300
in receiver mode is set to undither and an
undithered SDI or ASI signal is received,
the signal will be output normally, without
dithering.
