Endcaps
Refer to the “MX3 User’s Guide” for the section titled “Scanner Warnings and
Labels” for important laser safety information before using the scanner.
The Scanner/Serial Port and the Dual Serial Port are designated COM 1. The COM2 port is the IR
port.
Note: Your configuration may be different than those shown below.
COM Port Switching
The default COM 2 port is always the IR port on the back of the MX3, regardless of the endcap
installed on the MX3.
On the Standard Range Scanner / Serial Port endcap COM 1 is the Integrated Scanner port.
On the Dual Serial Port endcap the COM1 port is the serial port on the left side of the endcap
when the display is facing you.
An API can be run to switch power to the DB9 Serial port. If a tethered scanner is connected to
the Serial Port without switching the power to the COM2 port (serial port), the scanner will not
work.
