Integrated Scanner Port
The integrated laser 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 integrated laser scanner scans only when the Scan button is pressed. Scan buttons have no
effect on tethered barcode scanners connected to a serial port on the endcap or to the serial port on
a cradle holding an MX3X. The SCNR LED illuminates during any mobile device integrated
scanner activation.
The mobile device has an SE923 or SE955 scanner engine.
If you need to set up the integrated scanner barcode reading parameters, please refer to the
“Integrated Scanner Programming Guide” and the “MX3” barcode scanner type. The guide
is on the LXE Manuals CD and the LXE ServicePass website.
After scanning the barcodes that change Baud Rate, Parity, or Stop Bits go to Start |
Settings | Control Panel | Scanner | COM 3, make the same changes, and save the
changes by tapping OK.
