computer.
This cabling requires a straight-through PS/2 to DB-9 cable adaptor with the following
connector pinouts:

Notes:
• This procedure is not applicable to MP-112 as this model does not provide an RS-
232 serial interface port.
• The PS/2 to DB-9 cable adaptor is not included in the MP-11x package.
To connect MP-11x to a computer for serial communication:
1. Connect the PS/2 connector on one end of the cable to the MP-11x RS-232 port
(labeled RS-232).

2. Connect the DB-9 connector at the other end of the cable to either the COM1 or COM2
RS-232 communication port on your computer.
