avoid injury, data loss, or a system crash. When this symbol is marked on a
product, refer to the Specifications section for information about
precautions to take.
bold Bold text denotes items that you must select or click in the software, such
as menu items and dialog box options. Bold text also denotes parameter
names.
italic Italic text denotes variables, emphasis, a cross reference, or an introduction
to a key concept. This font also denotes text that is a placeholder for a word
or value that you must supply.
monospace Text in this font denotes text or characters that you should enter from the
keyboard, sections of code, programming examples, and syntax examples.
This font is also used for the proper names of disk drives, paths, directories,
programs, subprograms, subroutines, device names, functions, operations,
variables, filenames, and extensions.

Installing Cables
Complete the following steps to install the NI SHC68-C68-D2 cable and
any 50 Ω SMB cables.
Caution Disconnect power from the device, accessory, and any other connected hardware
before connecting the cable to prevent damage to the hardware and personal injury. NI is
not liable for damage resulting from improper connections.
1. Install the driver software and digital waveform generator/analyzer
Note Always install the module in a computer or PXI/CompactPCI chassis before
attaching any cables or accessories.
2. Attach either end of an NI SHC68-C68-D2 cable assembly to the DDC
Notes Do not use cables other than the NI SHC68-C68-D2 cable with this accessory.
Do not use the NI SMB-2163 accessory with differential digital signals, such as the digital
pattern output of the NI PXI-5421 signal generator.

cable with the captive screws on the cable connector.
The NI SMB-2163 is not compatible with the NI 6533/6534 products.
3. Attach and secure the other end of the NI SHC68-C68-D2 cable
assembly to the DDC connector of the NI SMB-2163 and secure them
together with the captive screws on the cable connector.

Connecting Signals
The NI SMB-2163 provides connectivity to up to 32 single-ended DIO
channels, three programmable function interface (PFI) channels, and
two clock channels of an NI digital waveform generator/analyzer. You
can connect to these signals from the labeled SMB connectors on the
NI SMB-2163.
Caution Connections that exceed any of the maximum ratings for the NI SMB-2163
or the NI digital waveform generator/analyzer can damage the device and the computer.
Maximum input ratings are provided in the specifications document that shipped with the
NI digital waveform generator/analyzer. NI is not liable for any damages resulting from
such signal connections.
Figure 3 shows the pinout of the DDC connector of the accessory. Each
DIO, PFI, and clock channel is connected to a corresponding pin on the
NI SMB-2163.
Table 1 describes the DDC signals in the pinout.
