Available Communications Cables/Converters
To simplify the wiring and connection process IMS offers a USB to RS-422 communications cable for the MForce Mi-
croDrive. This convenient 12.0' (3.6m) accessory cable connects a PC’s USB Port to the MForce MicroDrive P2 Connec-
tor. An in-line RS-422 converter enables parameter setting to a single MForce MicroDrive. Cable purchase recommended
with first orders.

For more information on these cables please reference Appendix D: Optional Cables and Cordsets.
Interfacing Single Mode Communications
The MForce MicroDrive communicates to the host using the RS-422/485 protocol. Communications may be configured
as either half duplex (RS-485) or full duplex (RS-422) using the EM (Echo Mode) Instruction. RS-422/485 may be used
in two ways: either to communicate to a single MForce MicroDrive, or to address up to 62 individually named MForce
MicroDrive nodes in a multidrop system.
Single Mode Communications Full Duplex (RS-422)
To interface the MForce MicroDrive using RS-422 protocol you will need one of the following:
A PC equipped with RS-422 Interface.
A PC RS-232 to RS-422/485 Converter.
The USB to RS-422 accessory cable.
Use the following diagram to connect RS-422 communications to the MForce MicroDrive.
