Overview

Product overview

Key product information and technical features.

The R1005050 provides a split connection from a supported device's 100-pin I/O connector to one or two 50-pin accessories. The NI 651x manual documents its use with CB-50 and CB-50LP terminal blocks.

Connector count alone does not establish compatibility. NI distinguishes the R1005050 from the NB5 cable by both its 100-pin connector and its 50-pin connector pin assignments, and directs users to the connected device's manual for the applicable pinout.

Y-shaped ribbon assembly provides two 50-pin branches from one 100-pin device connection.
The two 50-pin connectors are identified by pin groups 1–50 and 51–100.
Documented for connecting the PCI-6025E to 50-pin signal accessories.

FAQ

Product-specific questions

Product-specific answers based on available technical information.

Is R1005050 also called R100M-50F-50F?

Yes. NI's R100M-50F-50F product page explicitly identifies R1005050 as another name for this cable.

Does the R1005050 work with the PCI-DIO-96?

Yes. NI explicitly confirms that the R1005050 cable assembly is compatible with the PCI-DIO-96 and refers users to the device manual for connector pinouts.

Can an NB5 cable be treated as interchangeable with R1005050?

No. NI documents different 100-pin connectors and different 50-pin pin assignments. Its comparison identifies NB5 for PC-DIO-96 and PC-DIO-96/PnP, while R1005050 serves other specified 100-pin devices.
