118 6800/7000 Series - Distribution and Routing Products Installation and Operation Manual
Selecting V-trig (J10)
The V-trig detector circuit uses the embedded line count for 143/177
Mb/s D2 data and the vertical end of active picture information in 270
Mb/s D1 data. If this information is in error or missing, turn the V-trig
detector Off. However, the control circuit will “time out” and operate
when the V-trig is missing.
Selecting Single/Dual Bus (J11)
If J11 is in the V position, then this module responds to control as a
single video bus only. If J11 is in the V+A position, then this module and
an audio module sharing the same control panel will operate as a “tied”
video/audio router.
Connection
When using a DA mounting frame, the connectors are as follows:
Research indicates that non-isolated inputs have less common mode
rejection and, as a result, shorter cable equalizing capabilities.
All inputs satisfy the
650 ft (200 m) performance figure.
The control cable must be
terminated
even if the remote
panel is not used.
Output Input
Input Input 1, return isolated
Output 1 Input 2, return not isolated
Output 2 Not used
Output 3 Input 3, return not isolated
Output 4 Control in parallel with output 6
Output 5 Input 4, return not isolated
Output 6 Control must be terminated
Output 7 Output 1
Output 8 Output 2
It is recommended that the
user terminates all unused
inputs and outputs.
