For 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 devices and modules featuring the SCSI 0.050 D-Type connector . The SH68-68-EPM cable is a newer design featuring additional shielding and specific cable pairings to improve noise performance.
The SH68-68-EP is a shielded 68-conductor cable terminated with two 68-pin female SCSI 0.050 D-Type connectors. This cable connects to many 68-pin E Series NI60xxE devices (except DAQCards) and a number of accessories.
The specifications for the conductors in the SH68-68-EP cable depend upon which conductors you are referring to.
Note: These specifications are typical. They are not warranted and may change.
