Connecting To Video Devices
Video input and output devices (such as monitors or recorders) may be connected to the routing
switchers through the BNC type connectors located on the back of the unit. Keep in mind that the
output signal format will be the same as the input signal.
All signal connections that use more than one cable interconnecting between devices should be
of equal timing length (example: cables between a camera and the switcher should have the
same time delay).
Unused outputs do not need to be terminated.
Connecting Peripherals
Control panels, sync inputs, and power are all connected to the rear of the processor frame. The
peripherals area may vary depending on the model size and type.
Control System Connections
