The SPI (Serial Peripheral Interface) for the MDrive17/23 with C Connector
utilizes a 12 Position, Keyed and Locking Pin and Receptacle. The recom-
mended method of connecting to this receptacle is the Parameter Setup Cable.
Included in this cable is built-in logic level shifting circuitry to accommodate
the 3.3v ports on some PCs. This cable is 6 feet in length and connects a
standard DB-25 PC parallel/SPI port to the 12 pin side of the Adapter. Order
Cable Part Number MD-CC100-000 plus Adapter Cable Part Number MD-
ADP-1723C. Once the MDrive is configured, the SPI Interface can be
connected through the Prototype Development Cable, Part Number ADP-
3512-FL.

NOTE: Should you choose to make your own parameter
setup cable, be advised the 3.3V output parallel ports on
some laptop PCs may not be sufficient to communicate with
the device.
