Signal Connections
This chapter describes cable connections for the PCI-1409 and PXI-1409
devices.
BNC Connector
The BNC external connector supplies an immediate connection to the
1409 device VIDEO0 input. Use the 2 m BNC cable shipped with the
PCI/PXI-1409 to connect a camera to VIDEO0. You cannot use this
connection with VIDEO0 on the 68-pin VHDCI I/O connector. You
can configure the BNC connector only for RSE mode.
Note
Verify that Jumper W1 is installed when using the BNC input.
