Signal Connections
This chapter describes cable connections for the PCI-1408 and
PXI-1408 devices.
BNC Connector
The BNC external connector supplies an immediate connection to the
1408 device VIDEO0 input. Use the 2 m BNC cable shipped with the
PCI/PXI-1408 to connect a camera to VIDEO0. You cannot use this
connection with VIDEO0 on the 25-pin DSUB I/O connector. You can
configure the BNC connector only for RSE mode.
Note:
Jumper W1 must be installed when using BNC input.
Figure 4-1. BNC Connector Pin Assignment
I/O Connector
The 25-pin DSUB connector connects to all video signals (VIDEO0,
VIDEO1, VIDEO2, and VIDEO3), the external digital I/O lines and
triggers, and external signals. To access these connections, you can
build your own custom cable or use one of the optional cables from
National Instruments. Figure 4-2 shows the pinout of the 25-pin DSUB
connector.
Note:
Do not use the VIDEO0 connection on the 25-pin DSUB connector with the
BNC connection.
