650x/651x/652x Models : DAQ Digital I/O Cable and Accessory Compatibility Guide

Overview

Use this guide to match your NI Digital I/O (DIO) 65xx Models PCI, PCI Express (PCIe), PXI, or PXI Express (PXIe), or USB DAQ product with a compatible cable and accessory to meet the needs of your application, replacing or expanding your current configuration, or verifying that existing parts can be used in a different configuration.

NI Digital I/O (DIO) 65xx Models allow for digital input and output through a variety of connectivity options.

Note: This guide is for standard Digital I/O NI 650x, 651x, and 652x models listed below. Other NI 65xx Digital Instruments models are covered in a separate guide.

This page is part of the NI DAQ Multifunction I/O Cable and Accessory Compatibility Guide.

How to Use this Guide

It is important to work through this guide sequentially to identify and then pair up your device with compatible cables and accessories. To do this, complete the following steps:

  1. Find your module or device in hadrethe Device List.
  2. Use the Cable and Accessory Compatibility Tables to identify your device.
  3. Check the Known Limitations and Issues List for any known limitations you may encounter.

Note: Using the page search functionality in your browser to locate your model may speed up this process, typically CTRL+F on Windows or ⌘+F on OS X.

Note: This guide does not cover USB-65xx DAQ OEM models, refer to your 65xx OEM User Guide for wiring and connection considerations.

Device List

Begin by using the following tables to locate your device or module. Once found, note your connector type, pin count, and any other notes for reference. Next, move to the Cable and Accessory Compatibility Tables.

Important Note: "Group" used in this context is solely to categorize devices together that use the same cables and accessories. It does not necessarily indicate similar functionality, specifications, or other commonalities between the devices.
