Note The NI USB-7856R OEM device has plated mounting holes that can act as chassis ground.
To connect non-referenced single-ended voltage signals to the NI USB-7856R OEM device, you must connect the voltage ground signal to AI SENSE in order to keep the common-mode voltage in the specified range, as shown in Figure 4. Figure 4. Connecting Non-Referenced Single-Ended Signals to the NI USB-7856R OEM Device Overvoltage Protection PGIA...

V) and 3 and the negative connection. To connect the remaining LEDs, refer to Table 3. National Instruments recommends that you limit the current to 10 mA per LED. You can limit this current by using external resistors, as shown in Figure 9.
Figure 10. Attaching External LEDs OEM (On-Board) +5 V External Resistor External Power Switch Use the power switch to power the NI USB-7856R OEM device on and off. The following figure shows the pins on the power switch and power circuitry. Figure 11.
Caution Never connect the +5 V power terminals to analog or digital ground or any other voltage source on the NI USB-7856R OEM device or any other device. Doing so can damage the device and the computer. National Instruments is not liable for damage resulting from such a connection.
