Getting Started with R Series Intelligent DAQ
The +5V terminals on the I/O connector 5 V referenced to D GND. Use these terminals to
power external circuitry. All NI 78
xx
R devices are equipped with a fuse to protect the supply from
overcurrent conditions. Refer to the
R Series Intelligent DAQ User Manual
, available at
ni.com/
manuals
, for information about the device-specific fuses.
Connectivity Options
Accessing the signals on the I/O connectors requires at least one cable and one signal accessory. Table 1
summarizes the National Instruments connectivity options available for use with the NI 78
xx
R device.
For detailed information about connecting I/O signals, refer to the
