Endcaps and COM Ports
The MX3-RFID supports three COM port options. Two external serial ports are dependent on the
end cap chosen. A third serial port is used to support an integrated infrared transciever (barcode
reader). An additional endcap configuration supports serial and USB “slave” input/output at 1.5
MBps.

The COM 2 port is always the IR port on the back of the mobile device, regardless of the type of

On the Standard Range Scanner / Serial Port endcap COM 3 is the Integrated Scanner port. The

parameters, select Start | Settings | Control Panel | Scanner. Change the parameter values and
tap OK to save the changes.
On the Dual Serial Port endcap the COM1 port is the serial port on the right side of the endcap
when the display is facing you.
