Each channel of the NI 9263 has an AO terminal to which you can connect the positive lead of a load. Each channel also has a common terminal, COM, and there is an additional COM terminal at the bottom of the connector. All of the COM terminals are internally connected to the isolated ground reference of the module.

Protection Amplifier NI 9263 Figure 4. Output Circuitry for One Channel of the NI 9263 When the module powers on, the channels output the startup voltage. Refer to the Specifications section for more information about startup voltage. Refer to the software help for information about configuring startup output states in software.
Wiring for High-Vibration Applications If an application is subject to high vibration, National Instruments recommends that you either use ferrules to terminate wires to the detachable screw-terminal connector or use the NI 9932 backshell kit to protect the connections. Refer to Figure 5 for an illustration of using ferrules.
