Physical Controls

Programmable Scan Buttons

There are two buttons, one on each side of the display. The buttons can be programmed to perform
specific functions. The programmable keys have no effect on barcode scanners tethered to the
device. When there is no integrated scanner installed, both buttons default to Enter buttons (with
the exception of IBM 5250 terminal emulation devices – in this case, the left button is labelled and
functions as "Field Exit").
Note:
To edit the button parameters, select Start | Settings | Control Panel | Scanner | Keys. Change
the parameter values and tap OK to save the changes.
The default setting for the right button for the MX3X and the MX3P is Enter. The default setting
for the left button is Scan. When the device does not have an integrated scanner, both buttons
default to Enter keys and the Scan selection is greyed out.
Each button can be setup as:
• Disabled – no response when pressed
• Scan – initiate a barcode scan sequence (integrated scanner only)
• Enter Key
• Tab Key
• Field Exit (IBM 5250 / TN5250 devices only)
• Virtual Key (default values F20 and F21)
• RFID Read

Scan Buttons and the SCNR LED

The SCNR LED, located above the keypad, illuminates during an integrated barcode scanner
function. It is affected by internal scanner algorithms.
• Red – scanning.
• Green – good scan.
• Unlit – laser scanner is inactive.
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. Pressing the
trigger on the tethered scanner has no effect on the mobile device's Scan buttons.

The programmable Scan key is the Field Exit key when the MX3X is an IBM 5250 /
TN5250 compatible device. It can also be programmed as the RFID Read key for an
MX3-RFID device.
The Field Exit key is used to exit an input field. If the field is an Auto Enter field, the
auto transmit function is activated. This key function is present on the IBM
5250/TN5250 specific keypad only.
