3.4.4 Connecting MP-124 to a Computer for Serial Communication
The procedure below describes how to connect the MP-124 to a computer for serial RS-232
communication.
This cabling uses a standard, straight-through cable with DB-9 connectors on either end,
with the following connector pinouts:

.
ļ To connect MP-124 to a computer for serial communication:
1. Connect the DB-9 connector on one end of the cable to the MP-124 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.
Once you power-up MP-124, the Ready and LAN LEDs on the front panel light up green
(after a self-testing period of about a minute). Any malfunction in the startup procedure
changes the Ready LED to red.
For information on establishing a serial communication link with MP-124, refer to the User's
Manual.
