NI 653x Cable Adapter
Contents
The NI 653x cable adapter interfaces with National Instruments high-speed
digital I/O (DIO) devices. The cable adapter provides an easy way to
connect the Very High Density Connector Interface (VHDCI) connectors,
labeled as Digital Data & Control, on the NI 6535/6536/6537 devices and
NI 6535B/6536B/6537B devices to the 68-pin DAQ connectors found on
older NI 6533/6534 accessories and fixturing. The cable adapter is also
compatible with the NI 654x and NI 655x digital pattern
generator/analyzer devices.
For best signal integrity, NI recommends using the NI 6535/6536/6537 and
6535B6536B/6537B devices with newer accessories such as the
NI CB-2162 and NI SMB-2163.
This guide explains how to set up and use the NI 653x cable adapter.

Page 6: Connecting Signals
Connecting Signals The NI 653x cable adapter provides connectivity to up to 32 of the single-ended DIO channels of an NI high-speed DIO device. Each DIO, PFI, and clock channel of the NI high-speed DIO device connects to a corresponding pin on the NI 653x cable adapter. The 32 DIO channels are directly connected between the two bulk connectors. - Page 7 Refer to the help file for your device for information about the number of available DIO channels on your device.
