Chapter 14: VSR-4041 Serial Video Router Module Installation

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)

The control cable must be terminated even if the remote panel is not used.

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

It is recommended that the user terminates all unused inputs and outputs.

When using a DA mounting frame, the connectors are as follows:

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

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.
