COM 1 port is always the 17-pin port on the base of the MX6. COM 1 port accepts RS-232, USB
and AC power connectors.
The RS-232 port on the docking cradle is “connected’ to the MX6 when the MX6 is in the
docking cradle. The docking cradle must be powered by an alternate AC or DC power source to
enable communication.
The COM 3 / 6 port is always the IR port on the left side of the MX6. It is accessed as COM3 for
Raw Infrared communication and as COM 6 for Infrared communication using IrDA protocol.
To use COM 3 for Raw IR communication, select Start | Settings | Connections | Beam and
uncheck “Receive all incoming beams …”. This action disables IrDA protocol.
