Overview

Product overview

Key product information and technical features.

The SH6850 connects supported 68-pin DAQ device interfaces to 50-pin signal accessories. NI also identifies this cable family as SH68-50, with female SCSI and IDC connectors and shielded, twisted-pair construction.

The PCI-6023E and PCI-6024E user manual explicitly lists the SH6850 for connections to 50-pin signal accessories. The DAQCard-6024E uses a different cable-and-adapter arrangement, so that connection should not be treated as interchangeable.

FAQ

Product-specific questions

Product-specific answers based on available technical information.

What connectors does the SH6850 use?

It uses a 68-pin female SCSI connector and a 50-pin female IDC connector.

Can the SH6850 connect a PCI-6024E to a 50-pin signal accessory?

Yes. NI's user manual lists the SH6850 as a cable option for connecting PCI-6024E and PCI-6023E devices to 50-pin signal accessories. Verify the accessory's signal assignments before connecting.

Is the DAQCard-6024E connection the same as the PCI-6024E connection?

No. NI specifies a 68M-50F adapter used with an SHC68-68EP or RC68-68 cable for the DAQCard-6024E, rather than the direct SH6850 arrangement listed for the PCI devices.

What length is part number 776784-01?

NI identifies 776784-01 as the 1 m SH6850 version. Confirm the part number on the cable when identifying a particular unit.
