Setting Up Video Referencing
If you have installed your routing switchers for video referencing (see “ Connecting a Video Reference to
NK Series Routing Switchers ” on page 32), you need to set up the switching point to a predefined line for a
particular format, or you can set up a custom switching line to match the timing requirements of your system.
To set up video referencing
1. Open the NK-3G144 device tab (see “ The NK-3G144 Device Tab ” on page 36).
2. Select the Config tab.
3. Use the information in Table 5.5 to select the point on which you want the signal switching to occur:
4. If you have selected a switching point of Custom , use the information in Table 5.6 to set the custom switching
point.
5. Send the current file to the device (see “ Sending a Configuration File to a Device ” on page 47).
Saving the Current File for the Routing Switcher
The parameters that you have set up on the device tab for a routing switcher are stored in a configuration file. When
you have finished making changes to the configuration of the routing switcher, you should save the file and then
add the location of the file to the
File Navigator so that you can conveniently access it later.
