Overview

Product overview

Key product information and technical features.

The SHC68-68-EP provides a shielded connection between compatible NI DAQ hardware and external accessories. Its two ends use different connector formats: VHDCI at the device and SCSI 0.050-series D-type at the accessory.

NI's cable guide distinguishes this previous-generation EP design from the newer SHC68-68-EPM, which adds shielding and revised cable pairings. Select the cable using the exact DAQ device, connector, and accessory requirements rather than the shared 68-pin designation alone.

FAQ

Product-specific questions

Product-specific answers based on available technical information.

Does the SHC68-68-EP have the same connector at both ends?

No. It uses a 68-pin VHDCI device connector and a 68-pin SCSI 0.050-series D-type accessory connector.

Is the SHC68-68-EP the same as the SHC68-68-EPM?

No. NI identifies the EP as a previous-generation design. The EPM adds shielding and specific cable pairings to improve noise performance; substitution must be checked for the particular device.

Is this catalog item confirmed to be 2 meters long?

The supplied record does not establish the item's length. NI documents part number 186838-02 as a 2 m SHC68-68-EP variant; confirm the item's part-number label before selecting a length.

Does the SHC68-68-EP have identical connectors at both ends?

No. NI identifies a VHDCI device connector and a SCSI 0.050 series D-type accessory connector, both with 68 positions.

How does it differ from the SHC68-68-EPM?

NI describes the SHC68-68-EPM as a newer design with additional shielding and specific cable pairings to improve noise performance. Do not transfer EPM electrical specifications to the EP model.

Is this catalog record confirmed to be a 2 m cable?

No. NI documents a 2 m SHC68-68-EP under part number 186838-02, but the supplied catalog record does not specify a part number or length for the actual unit.
