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 newer NI 6535/6536/6537
devices to the 68-pin DAQ connectors found on older NI 6533/6534
accessories and fixturing. The 653x 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
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.
