Tethered Scanners
The MX3-CE 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.
To set the MX3-CE to use a tethered scanner, select Start | Settings | Control Panel | Scanner |
COM1 (or 2 or 3).
Click 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.
