CAT5 MULTI VIDEO SYSTEM.
Appendix B. Setting Sync Signal
Output Termination
In some cases, it may be necessary to disable the 75-ohm termination of the video
outputs on the CAT5 Multi Video System units. This can be done by opening the
case of each unit and installing jumpers on the circuit board. The settings
disable/enable the 75-ohm termination on individual units. For instance, changing
a transmitter termination affects the local monitor port only; it doesn’t affect the
receivers. Conversely, changing a receiver affects the output port of the receiver,
not the transmitter. The following diagrams show the jumper locations for each
type of assembly reference the transmitter manual for transmitter settings.
