Page 5: Installing Cables
Before connecting the cable, disconnect power from the module, accessory, and Caution any other connected hardware to prevent damage to the hardware and personal injury. NI is not liable for damage resulting from improper connections. Install NI-HSDIO or NI-DAQmx and the digital waveform generator/analyzer by following the installation procedure in the Getting Started Guide that shipped with your device. -
Page 6: Connecting Signals
Refer to Figure 1 for the location of these pins on the NI CB-2162. Before powering down the digital waveform generator/analyzer module, remove Caution power from the prototyping area of the NI CB-2162.

- Page 9 Using 1 × 2 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 1 × 2 header receptacle to a coaxial cable assembly.
- Page 10 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.

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 Thevenin (Dual) Termination In some applications, you might need to provide a Thevenin (dual) termination or a pull-up and pull-down configuration. Figure 9 shows a typical dual-termination resistor network, which can accomplish this task. © National Instruments Corporation NI CB-2162 User Guide...

You will not need the washers to mount the NI CB-2162 in the CA-1000. Save the Note washers in case you ever need to remove the NI CB-2162 from the CA-1000 and use the NI CB-2162 outside the enclosure. © National Instruments Corporation... - Page 18 Figure 12. Position the NI CB-2162 on the standoffs of the CA-1000. Secure the NI CB-2162 in the bottom of the CA 1000 using two of the screws provided in the NI CB-2162 CA-1000 Mounting Kit. Place the lower edge of the VHDCI panellete in the groove at the bottom of the enclosure opening.
