1. Loss of video will be a major alarm if the “Video Loss Alarm” is enabled (SW2, switch S8 is OFF).
2. The “Missing SFP” alarm is enabled if the SFP optical receiver is selected (SW2, switches S3, S4, and S5 are ON) or the
optical repeater is enabled (SW3, switch S7 is OFF).
Using the DLC170DA Monitor Jack
The front panel monitor jack can be set to output either the input digital video (including embedded audio) or
the output analog video. When the output is set to digital, you can monitor the incoming digital video in
270 Mb/s SDI format with embedded audio for signal level and quality using digital video test equipment.
When the output is set to analog, you can monitor the converted video using conventional analog video
equipment.
To connect a monitor to the DLC170DA, perform the following steps:
1. Connect the monitor cable between the monitor and the mini 75 Ohm SMB monitor jack (MON) located
on the DLC170DA front panel (see Figure 19 ).
2. Switch the monitor select switch to the desired position:
• D—Display the digital video that the DLC170DA is receiving.
• A—Display the analog video output that the DLC170DA is transmitting.
