Connecting A Tethered Scanner - Honeywell MX3Plus User Manual

Connecting a Tethered Scanner

Do not connect a tethered scanner cable to a USB-C or USB-H labeled endcap port. The USB ports cannot power a tethered
scanner. The tethered scanner draws power from the MX3Plus.
The MX3Plus Scan buttons have no effect on tethered bar code scanners (connected to a serial port). Tethered scanners read
bar code scans only when the trigger on the tethered scanner is pressed. The tethered scanner requires power on pin 9 of the
MX3Plus's serial port.
To set the MX3Plus 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.
