This document provides engineers with a group of connectors (symbols and landpatterns/footprints) for you to define custom circuitry, breakout boards, user defined modules and daughter cards for National Instruments hardware.

These symbols and footprints for NI circuit design tools represent common interface connectors to NI DAQ, Single-Board RIO and CompactRIO.

All symbols and footprints for these connectors are free for you to use in NI Multisim capture (schematic symbols), and NI Ultiboard layout (footprints). By leveraging these resources, you can quickly and easily build custom hardware that interface complex signals to your prototypes.

1. Why do I need these Connectors?

Defining symbols and footprints for hardware specific connectors can be both time consuming and difficult. Ensuring that pin spacing, mapping and dimensions are all correct can take as much as a few hours to design.

Engineers who use National Instruments hardware products must sometimes expand their hardware needs outside of off-the-shelf parts. For example it may be necessary to take the output from a DAQ card, and use a break-out board to break out each individual signal for specific use. For prototyping platforms such as CompactRIO or Single-Board RIO, you may need to create some form of accessory such as a C-Series Module, or daughter card, which will allow you to do perform additional conditioning upon a signal.

Due to the custom nature of such designs, you need access specific connectors. Much of this information can be found within datasheets, but can be difficult to either read, or time consuming to create manually. As such the ability to have these connectors in a readily available form – ready to use within your NI Multisim and NI Ultiboard design tools - can significantly aid the design process.


Support of Connectors

These connectors have been made available through our Applications Engineering and Marketing department, however are not supported components. They can assist you in completing your design needs, but are not a product to be purchased or supported through SSP, as an individual product.


Software Requirements

You will require the Circuit Design Suite software (containing Multisim and Ultiboard) to be able to utilize the attached resources. You can download an evaluation edition of Multisim and Ultiboard at the following online destination.

Connectors Format

Each of the connectors included in this online resource have generic pin mappings. This means although the connector landpattern are defined accurately for physical shape, size and format (all to IPC standards), the specific pin names for each individual connector are not contained.

For additional information on the specific pin names for each ‘product’ please consult the product specific links above to see pin mappings.

4. Installing your Database Update

To install the attached custom connectors (from your database:


  1. Open Multisim ( Start > All Programs > National Instruments > Circuit Design Suite 10.1 > Multisim 10.1).
  2. Double-click on the NI_Hardware_DB.prz file.
  3. In the Database Merge dialog box select User Database as the Target Database
  4. Click on the Start button.
  5. Once status is "Done" click on the Close button.


  1. Open Ultiboard (Start > All Programs > National Instruments > Circuit Design Suite 10.1 > Ultiboard 10.1).

Connector reference libraray for EAGLE?  - Jan 28, 2015

We are using CadSoft EAGLE for PCB layouts. Is it possible to provide a reference library for this software too?

Other Connectors  - Aug 8, 2011

I'm currently doing a project involving connectors for MXI-2 and GPIB. Is there any way to request that these connectors be made available in Multisim and Ultiboard?
