NI CB-2162

Single-Ended Digital I/O Accessory

The NI CB-2162 is a connector block and prototyping board for 
National Instruments digital waveform generator/analyzer modules. 
The NI CB-2162 provides an easy way to complete the following tasks:

Terminate digital I/O (DIO) and control channels

Connect to other devices for testing and debugging

Develop and interface to prototype circuits

Probe DIO and control channels

This guide explains how to set up and use the NI CB-2162 single-ended 
DIO accessory.
