Installing Cables

Complete the following steps to install the NI SHC68-C68-D2 cable and

any 50 ΩSMB 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

by following the installation procedure in the NI Digital Waveform

Generator/Analyzer Getting Started Guide.

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

connector of the digital waveform generator/analyzer and secure the

cable with the captive screws on the cable connector.

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.

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.
