Caution Before attaching any cables or accessories, install the digital waveform
generator/analyzer in a PXI/CompactPCI chassis. Refer to the NI Digital Waveform
Generator/Analyzer Getting Started Guide for instructions on installing the module.
2. Attach either end of an NI SHC68-C68-D2 cable assembly to the
DDC connector of the digital waveform generator/analyzer module
and secure the cable with the captive screws on the cable connector.
3. Attach the other end of the NI SHC68-C68-D2 cable assembly to the
DDC connector of the NI CB-2162 and secure them together with the
captive screws on the cable connector.
Connecting Signals
Each DIO, PFI, and clock channel of the digital waveform
generator/analyzer connects to a corresponding pin on the NI CB-2162.
Refer to Figure 1 for the location of these pins on the NI CB-2162.
Caution Before powering down the digital waveform generator/analyzer module, remove
power from the prototyping area of the NI CB-2162. NI is not liable for any damage
resulting from improper signal connections.

Table 1 describes the DDC signals shown in Figure 3.
The NI CB-2162 provides connectivity to up to 32 of the single-ended
DIO channels of an NI digital waveform generator/analyzer. The 32 DIO
channels are divided into two bundles of 16x2 header pins. Each bundle is
grouped by signal and ground pairs. The ground pins provide ground return
paths for the DIO channels.
You can make connections to the DIO channels, the PFI channels,
DDC CLK OUT, or STROBE on the NI CB-2162 using a 1x2 header
receptacle, ribbon cable, a wire-wrap technique, or by soldering directly to
the pins. Examples of how to make these connections are provided in the
following sections.
Caution Connections that exceed any of the maximum ratings for the NI CB-2162 or the
NI digital waveform generator/analyzer module can damage the module and the computer.
Maximum input ratings are provided in the Specifications section and in the specifications
document that shipped with the digital waveform generator/analyzer. NI is not liable for
any damage resulting from such signal connections.
Table 1. DDC Connector Pinout Descriptions
DDC Pin Signal Description
DIO<0..31> Bidirectional digital data channels 0 through 31.
STROBE External sample clock source for pattern
acquisition.
DDC CLK OUT Exported sample clock signal.
PFI <1..3> Programmable functional interface (PFI)
channels 1 through 3.
GND Ground reference for signals.
RESERVED These channels are reserved for system use.
Do not connect signals to these channels.

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.
Connectivity is made by inserting the receptacle onto the appropriate
header pair. Refer to the receptacle documentation to assure that proper
connections are made to signal and ground.
Figure 4 shows how to make 1x2 header receptacle connections.

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. NI recommends using short
twisted-pair ribbon cables.
Refer to the device or cable manufacturer for additional information on
proper connectivity to the NI CB-2162 signal and ground connections.
Figure 5 shows how to connect a ribbon cable to the accessory.
