Digital I/O Connections
The 100-pin high-density SCSI connector on the NI 6509 provides access
to 96 digital inputs and outputs. Use this connector to connect to external
devices, such as solid-state relays (SSRs) and LEDs. For easy connection
to the digital I/O connector, use the National Instruments SH100-100-F
shielded digital I/O cable with the SCB-100 connector block, or use the
R1005050 ribbon cable with the CB-50 or CB-50LP connector block.
Caution
