The +5V terminals on the I/O connector supply +5 V referenced to D GND. Use these terminals to
power external circuitry. All NI 78xxR devices are equipped with a fuse to protect the supply from
overcurrent conditions. Refer to the R Series Intelligent DAQ User Manual, available at
, for information about the device-specific fuses.

High-performance shielded cable wired
specifically for signal connection from the
RMIO connector
block to provide higher signal integrity and noise
immunity.
High-performance shielded cable wired
specifically for signal connection from the
RDIO connector
block to provide higher signal integrity and noise
immunity.
Basic shielded cable for signal connection from
the RMIO or RDIO connector to the NI SCB-68
terminal block for noise reduction.
For use with the NI PXI-78xxR running the
LabVIEW Real-Time Module, if the real-time
PXI system is not configured on a network.
To connect the PXI system to a network port, use
a standard CAT 5 10/100Base-T Ethernet cable.
