25.2.3 Connecting External Video Devices
Most SwitchPoint Infinity 3 Control System installations have extra inputs and outputs for
video. Some are terminated on the boom for easy access. One of the more common
devices connected is the fluoroscope or C-arm. There are two things to be aware of
when connecting these:
1. Older model C-arms have a small termination switch next to the BNC connection. If
you are not connecting an external device to the C-arm, the switch must be in one
position. This position puts a 75 ohm resistor across the output to properly terminate
the video. If you are connecting an external device, the switch needs to be turned off.
The wrong position will cause the video signal to be attenuated. Try both positions; it
will be obvious which is correct.
2. New C-arms have multiple outputs, one of which is scan-doubled. Scan-doubling is
an analog version of higher resolution video. This won’t display correctly on a
standard monitor or the SwitchPoint Infinity 2 Control System. On GE C-arms, the I/O
panel has three jacks with small TV icons above the BNC connector. One has twice
as many lines in it. This is the scan doubled output. Use one of the other jacks. Try all
three to determine which one works the best.
