Using the DLC170AD Monitor Jack
The front panel monitor jack can be set to output either the input analog video or the output digital video
(including embedded audio). When the output is set to analog, you can monitor the incoming analog video
signal for signal level and quality using conventional analog video equipment. When the output is set to
digital, you can monitor the converted video in 270 Mb/s SDI format with embedded audio using digital video
test equipment.
To connect a monitor to the DLC170AD, perform the following steps:
1. Connect the monitor cable between the monitor and the mini 75 Ohm SMB monitor jack (MON) located
on the DLC170AD front panel (see Figure 13 ).
2. Switch the monitor select switch to the desired position:
• A—Display the analog video source that the DLC170AD is receiving.
• D—Display the digital video that the DLC170AD is transmitting.
