Endcaps
The MX3-CE 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 infrared transceiver (barcode reader). An
additional endcap configuration supports serial and USB "slave" input/output at 1.5 Mbps.
Note: The USB port requires a DB9 to USB cable.

The default COM 2 port is always the IR port on the back of the MX3-CE, regardless of the type
of endcap installed on the unit.
On the Standard Range Scanner / Serial Port endcap COM 3 is the Integrated Scanner port.
On the Dual Serial Port endcap the COM 1 port is the serial port on the right side of the endcap
when the display is facing up.
Integrated Scanner Port
The MX3-CE Barcode Scanner is used to collect barcode data from any nearby compatible
barcode label. Depending on the size of the barcode, size of bars and spacing and quality of the
barcode, the scanner is used to read barcodes between 3" and 30". The barcode scanner reads
UPC/EAN, Code 39, Code 93, I 2 of 5, Discrete 2 of 5, Code 128, Codabar and MSI symbologies.
The internal barcode scanner scans only when the Scan button is pressed. Scan buttons have no
effect on tethered barcode scanners connected to the RS-232 port on the MX3-CE or a cradle
containing an MX3-CE. The SCNR LED illuminates during any internal scanner activation.
