Tethered Scanners
Do not connect a tethered scanner cable to a mobile device’s USB-C or USB-H labeled endcap
port. These ports cannot power a tethered scanner. Tethered scanners connect to RS232-labeled
ports on the endcap and can connect to the RS232 port on a powered cradle.
The Scan buttons have no effect on tethered barcode scanners (connected to a serial port).
Tethered scanners read barcode scans only when the trigger on the tethered scanner is pressed. The
tethered scanner requires power on pin 9 of the mobile device’s serial port.
To set the MX3X to use a tethered scanner, select Start | Settings | Control Panel | Scanner |
COM1 (or 2 or 3).
Tap the "Power on Pin 9 (+5V)" checkbox for the COM port selected. The COM port that accepts
the scanner data can be configured for data rate, parity, stop bits and data bits.

USB Port
The USB port requires a 9-pin to USB cable (available from LXE). The 9-pin port/USB port also
supports serial data transfer (using a null modem cable) and non-host USB I/O at 1.5 Mbps. The
operating system automatically detects the USB cable configuration. Refer to section titled
"Accessories" in this guide for part numbers for the 9-pin USB cable and the null modem cable.
