COM Ports

The MX7 has one mini D 20-pin serial port (a multifunction I/O port) that can be configured by the user.

RS-232 Serial Port

Configured as COM1. Bi-directional full duplex and supports data rates up to 115 Kb/s. The port does not have RI or CD
signals nor does it support 5V switchable power on pin 9 for tethered scanners. The serial port driver supports full duplex
communications over the serial port. It supports data exchange via ActiveSync, but does not automatically start ActiveSync
when connected. The "Cable, Multipurpose RS-232 and Power" and "Adapter, RS-232 terminal port to D9 male" accessories
can be used with the RS-232 serial port. External AC power is available when the multipurpose RS-232/Power cable is
connected. External AC power is not available for the "Adapter, RS-232 terminal port to D9 male" option. Power is drawn from
the main battery pack when this adapter is connected..

USB Client Port

The MX7 has one USB Client port for ActiveSync applications. An accessory USB cable, "Cable, Multipurpose USB and
Power" is available to connect the MX7 to a USB Type A plug on a PC for ActiveSync functions. External AC power is
available when the multipurpose USB Client/Power cable is connected.

Audio Connection

An audio headset interface is available using the "Adapter, Audio" accessory with the I/O port. The connection cable connects
the MX7 to a Voxware quick disconnect 4-pin interface. This cable adapts to specific styles of headsets for voice input, stereo
or mono output. The MX7 with a Summit Client supports mono only. A 3-wire connector with (at a minimum) connections for
ground, microphone, and 1 speaker. Connecting the headset to the MX7 COM port turns off audio output to the MX7 speaker
on the front of the mobile device. All sounds previously directed to the speaker are redirected to the headphone, including
beeps. Bias voltage for an electric condenser microphone is available. External AC power is not available for this option. Power
is drawn from the main battery pack.
