Communications Converters
Electrically Isolated, in-line converters pre-wired with mating connectors to conveniently set parameters and program a single MDrivePlus via a PC USB port.
| Converter Part Number | Mating Connector Type |
| MD-CC300-001 (USB to SPI) | 10-Pin IDC |
| MD-CC303-001 (USB to SPI) | 10-Pin Tyco |
If building your own cabling, you will need:
- SPI inline converter or PC parallel port
- Cabling with appropriate mating connectors for the MDrive model selected
Prototype Development Cables
Prototype development cables are designed to speed test/development with pre-wired mating connectors that have flying leads other end. No prototype development cables are available for the MDrivePlus using the 12' Flying Leads or Pluggable Clamp Terminal Strip.
| Prototype Development Cable P/N | Mating Connector Type | Signal Type |
| PD12-1434-FL3 | 12-Pin Locking Wire Crimp | I/O and Communications |
Prototype Development Cables will ONLY be used if you are using your own SPI communications converter.
If building your own cabling, you will need:
- Appropriate mating connector and crimp pins if required (Mating connector kits are available for Locking Wire Crimp style connectors)
- Crimp tooling (Locking Wire Crimp)
- Shielded twisted pair cabling
Mating Connector Kits
Mating Connector Kits are used to build your own cables. Kits contain 5 mating connector shells with pins. Cable not supplied. Manufacturer crimp tooling recommended.
| Mating Connector Kit P/N | Mating Connector Type | Shell Mfg. P/N | Crimp Pins Mfg. P/N |
| CK-01 | 10-Pin IDC | Samtec: TCSD-0501-N | -- |
| CK-03 | 12-Pin Locking Wire Crimp | Tyco: 1-794617-2 | Tyco: 794610-1 |
| CK-05 | 2-Pin Locking Wire Crimp | Molex: 510-67-0200 | Molex: 502-17-9101 |
