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.
