NI CB-2162
Single-Ended Digital I/O Accessory
Contents
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:
•
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.

Page 9: Using 1X2 Header Receptacles
Using 1x2 Header Receptacles Each signal and ground header pair is labeled on the NI CB-2162 and in Figure 1. These header pairs are arranged so that you can make quick connections using a 1x2 header receptacle, such as the 3M Monosignal Socket Connector (3M part number TS0870), to a coaxial cable assembly. -
Page 10: Using A Ribbon Cable
Using a Ribbon Cable The header pairs on the NI CB-2162 are available for single wire probing. You also can use 32-pin ribbon cables to easily connect a large number of channels to other devices. Cable type and quality can dramatically affect how well the signal integrity is maintained. -

Connect the DIO channel and ground header pins for each channel being used. Figure 6 provides an illustration for making a wire-wrap connection. 1 Wire-Wrap Tool 3 Header Pin Receptacle 2 Stripped Wire Figure 6. Wire-Wrap Connections © National Instruments Corporation NI CB-2162 User Guide... -
Page 12: Terminating Signals
To minimize the effect of stubs, termination is placed at the end of the signal path. If your signal transmission line ends on the NI CB-2162, you can use the provided termination socket. If your signal terminates somewhere other than the NI CB-2162, NI recommends terminating the transmission line at the final signal destination. - Page 13 Figure 7 can be inserted into pin 10 of the socket shown in Figure 8. External power can then be applied to the connection point located below pin 10 of the socket to provide proper termination. © National Instruments Corporation NI CB-2162 User Guide...
