VideoMUX (Video Multiplexer)

NI VMS is designed to use the VideoMUX as an external video signal input connection, multiplexing, and triggering interface.

Input Channels 8 + 8
Input Connectors BNC
Input Impedance (Ohms) 75
Output Channels 2
Output Connectors BNC
Output Impedance (Ohms) 50
CVBS/CAV Sync Extraction Yes
H+V Sync Extraction Yes
Trigger Output Yes
Remote Control Interface USB

The Ch0 and Ch1 outputs are designed to connect to the CH0 and CH1 inputs of the NI 512X digitizer. The trigger output is designed to connect to the TRIG external trigger input of the NI 512X digitizer.

The various combinations of signals (referred to as signal input modes) are detailed in the tables below.
