COM 1 port is always the left RS-232 port on the base of the MX5. COM 1 port accepts RS-232,
USB and AC power connectors.
The RS-232 port on the docking cradle is “connected’ to the MX5 when a tethered scanner is
connected to the RS-232 port on the MX5 cradle, and the MX5 is in the cradle. The cradle must
be powered by an alternate AC or DC power source to enable tethered scanner use.
The COM 3 port is always the IR port on the base of the MX5.
COM 4 is always the right RS-232 port on the base of the MX5. COM 4 port accepts RS-232 and
AC power connectors.
To edit Scanner Com Port parameters, tap the Windows icon | Settings | System | Scanner.
Change the parameter values and tap OK to save the changes.
USB Port
The USB port requires a DB26 to USB cable (available from LXE). The serial port/USB port also
supports serial data transfer (using a null modem cable) and non-host USB I/O at 1.5 Mbps. The
MX5 automatically detects the cable configuration.
Refer to section titled "Accessories" in this manual for part numbers for the DB26-USB cable and
the null modem cable.
