How to Make Connections to the Video References
Locate the video reference connections on the rear of the router, as shown in Figure 2-21. Video
reference connections are labeled ‘VIDEO REF 1’ and ‘VIDEO REF 2’.

9 Connect to the ‘VIDEO REF 1’ connection using a 75 Ω BNC connector and coaxial cable.
10 Connect the other end of the cable to a reference signal. Be sure the incoming signal is from a
stable source. The signals can be:
PAL
NTSC
Tri-Level Sync (1080i 50/59.94/60 and 720p 50/59.94/60)
11 On all unused video reference connections, be sure to terminate the loop-through by installing a
75
Ω BNC terminator.
12 Connect to the ‘VIDEO REF 2’ input connection, as described in Steps 9 through 11.
Making Monitor Connections
The NV8500 family of routers support the monitoring of output and input signals. Whether both
outputs and inputs are monitored depends upon the control card currently installed in the router
frame. Older control cards run an application that supports only output monitor signals. More
recent control cards run an application that supports both output and input signal monitoring.
Control cards running the following application versions support the listed monitor signals:
• Versions 13.0.3.xx and older – The control card supports output monitor signals only (matching
FPGA versions: SV0900-06, SV0901-05 and older).
• Versions 14.0.0.xx and newer – The control card supports both input and output monitor signals
(matching FPGA versions: SV0900-07, SV0901-06 and newer).
To properly access and control monitor cards and signals, a Monitor Level must be configured in
UniConfig. A level is an organizational partition in the router. Levels are based on signal type,
which for the Monitor Level is the monitor signal. A Monitor Level solely manages monitor sig-
nals.
UniConfig is a configuration application, run on a computer in the network, used to configure rout-
ers. This Application Note briefly outlines how to create “monitor levels” in UniConfig. For
detailed information on UniConfig, see the UniConfig User’s Guide.
