Signal Connections

This chapter describes cable connections for the NI 1409 devices.

BNC Connector

The BNC external connector supplies an immediate connection (RSE mode
only) to the 1409 device VIDEO0 input. To use the VIDEO0 connection on
the 68-pin VHDCI I/O connector, you must connect to the signal
and VIDEO0– to ground.

To connect a camera to VIDEO0, first verify that the W1 jumper is intact.
Next, use the 2 m BNC cable shipped with the NI 409 to connect to the
BNC connector.
