62xx Models : DAQ Multifunction I/O Cable and Accessory Compatibility

Updated Jul 15, 2024

Overview

Use this guide to match your NI Multifunction I/O (MIO) 62xx models PCI, PCI Express (PCIe), PXI, PXI Express (PXIe), or USB DAQ device 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 Multifunction I/O (MIO) 62xx models (formerly referred to as NI M Series) are the previous generation of NI MIO DAQ hardware. They allow for analog, digital, and counter input and output through a variety of connectivity options.

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

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 the 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.
  4. 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 MacOS.

 

Note: This guide does not cover USB 62xx DAQ OEM models, refer to your OEM User Guide and the M Series User Manual for wiring and connection considerations.

Known Limitations and Issues List

This section is important to review because not every cable and accessory combination allows access to the full functionality of your NI DAQ Multifunction I/O 62xx device or module. This list contains notes about known limitations when using certain combinations of DAQ cables and accessories. If your device or cable is not listed in this section, there are no known exceptions for it.

 

Devices and Modules:

Review this table to identify potential limitations and known issues with your device or module.

  • NI recommends that you use the SHC68-68 cable when the SCB-68 or SCB-68A is connected to Connector 1. You can not use the SHC68-68-EPM cable on these connectors.
  • Connector 1 cannot be used with SCC carriers (SC-2345, SC-2350, SCC-68).
  • BNC-2115 provides BNC connectivity to 24 of the differential (48 single ended) analog input signals on Connector 1. You can use a SH68-68-S cable to connect to the BNC-2115.
  • TB-2706 uses Connector 0 of your PXI device. After a TB-2706 is attached, Connector 1 cannot be used.

  • NI recommends that you use the SH68-68-S cable when the SCB-68 or SCB-68A is connected to Connector 1. You can not use the SH68-68-EPM cable on these connectors.
  • Connector 1 cannot be used with SCC carriers (SC-2345, SC-2350, SCC-68).
  • BNC-2115 provides BNC connectivity to 24 of the differential (48 single ended) analog input signals on Connector 1. NI recommends that you use the SH68-68-S when the BNC-2115 is connected to Connector 1. You can not use the SH68-68-EPM cable on these connectors.
  • The M Series User Manual (July 2016), P/N 371022L-01, incorrectly lists the SHC68-68 cable for Connector 1. The correct shielded cable for this model is the VHDCI SH68-68-S cable, as listed in this guide.

  • Review KnowledgeBase 4DB9G1A0 for Pinout Information when used with the BNC-2110.
  • When using the BNC-2110 only 46 of the 48 DIO pins are accessible.
  • If 2 BNC-2110 are used, extra care should be taken to ensure proper routing on the BNC-2110 connected to Connector 1 as the labels on the BNC-2110 will not match the pinout of the device.

 

 Cables:

Review this table for alternative cabling options.
ModelNote
SHC68-68-EPMFor VHDCI connections NI recommends that you use the SHC68-68-EPM cable; however, an SH68-68-EP cable will work with NI Multifunction I/O 62xx Models (formerly M Series). The SHC68-68-EPM cable is a newer design featuring additional shielding and specific cable pairings to improve noise performance.
SHC68-C68-EPMThe SHC68-C68-EPM can be used for any device or module for which the SHC68-68-EPM is recommended. The SHC68-C68-EPM is intended for custom breakout fixtures that use the VHDCI 0.8 mm connector. DAQ accessories only feature a SCSI 0.050 D-Type connector and will not work with this cable.
SH68-68-EPMFor SCSI 0.050 D-Type connections NI recommends that you use the SH68-68-EPM cable; however, an SH68-68-EP cable will work with NI Multifunction I/O 62xx Models (formerly M Series). The SH68-68-EPM cable is a newer design featuring additional shielding and specific cable pairings to improve noise performance.

Glossary

Review the DAQ Cable and Accessory Guides for more information about this terminology and other descriptors.

  • 0.050 D-Type - Industry standard SCSI connector standard featuring 0.050 pin spacing that is used in 50, 68 and 100-position DAQ cable and accessory connections. Click here for an example.
  • D-Sub (DSUB) - An industry standard 37-pin D-Sub connector. Click here for an example.
  • Ribbon Cable - A low-cost unshielded cable solution. Click here for an example.
  • Shielded Cable - A high performance cable solution that offers noise reduction through shielded conductors. Click here for an example.
  • Shielded Terminal Block or Connector Block - A high performance accessory solution offering very low-noise signal termination through shielding. Click here for an example.
  • Unshielded Terminal Block or Connector Block - An alternative low cost accessory solution that does not offer shielding. Click here for an example.
  • USB Device BNC Model - These USB Multifunction I/O DAQ devices provide most analog signal connections through a BNC cable connection. All 62xx models provide digital and PFI signal connectivity through screw terminal connections and some 62xx models also provide digital line and PFI signal connectivity through BNC connections. These devices do not require the use of additional cabling or accessories. Click here for an example.
  • USB Device Mass Termination Model - These USB Multifunction I/O DAQ devices do not provide any direct signal connectivity on the USB device. Instead all signals flow through cables and the VHDCI connectors to an accessory, as opposed to USB screw terminal or BNC variants. Click here for an example.
  • USB Device Screw Terminal Model - These USB Multifunction I/O DAQ devices provide all signal connections through a screw terminal connection. These devices do not provide signal connections through a cable and accessory. Click here for an example.
  • Very-High-Density Cable Interconnect (VHDCI) - An improvement on the SCSI 68-pin connector featuring .8 mm pin spacing, allowing a smaller footprint and fewer bent pins during connection. Click here for an example.
