Typical System Setup
Digital I/O configuration varies depending on the number of cameras your
system setup requires. You can access the digital I/O through the 44-pin
DSUB connector or through the three SMB connectors.
The digital I/O capabilities of the SMB connectors on the NI CVS-1450
device are ideal for typical single-camera applications. The SMB
connectors are labeled
TRIG 0

TRIG 1
, and
TRIG 2
.
