What Cables Do I Need With My NI-Motion Hardware?

Hardware: Motion Control

Problem:
I am trying to decide which cable to buy with my NI Motion Hardware. There are multiple options available on the Motion Advisors Website. What are the differences and which one do I need?

Solution:
There are three options available. The part numbers are as follows:

186380-XX
186381-XX
189041-XX

The -XX denotes one of three cable lengths:

-0R5: 0.5 meters
-01: 1 meter
-02: 2 meters

The differences between the cables are described in the following three sections.

Cable 1: SHC68-C68-S, 68 pin VHDCI to 68 pin VHDCI,

Part Numbers:

186380-01

186380-0R5

This cable has the same identical 68-pin VHDCI male connector on both ends. This cable is used when connecting from an NI-Motion Controller Card to NI Motor Drives (e.g. MID-7604/7602) and to the UMI-7772/4 connector blocks.

Note: This cable is not the same as the DAQ cable. The DAQ cable has wired common grounds and can create problems if used for Motion applications.

Cable 2: SH68-C68-S, 68 Pin VHDCI to 68 Pin .05 Series D-Type,

Part Numbers:

186381-01

186381-02

186381-0R5

One end of this cable has the standard VHDCI male connection seen above. The other is a 0.05 Series, D-Type SCSI male connector shown below. This is used with a UMI-7764 for connecting to 3rd party drives.

The full cable is shown below.

Cable 3: SHC68-NT-S Shielded Cable Assembly (unterminated)

Part Number:

189041-02

One end of this cable has the standard VHDCI male connection seen below.

The other end terminates with pig-tail leads for custom cabling. This can be used to connect directly to third party drives without the use of a UMI, or for OLE applications.
The full cable is shown below.
