NI 9403 Signal Descriptions

Signal Name

Description

DIO

Each channel includes a DIO pin to which you can

connect a digital input or output device.

COM

DIO channels are internally referenced to COM, so you

can use any of the four COM lines as a reference for the

external signal.

RSVD

This channel is reserved and is not a user-facing signal.

Connecting Digital Devices to the NI 9403

You can connect digital devices to the NI 9403.
