Scan Buttons
Figure 2-11 Programmable Buttons
There are two buttons, one on each side of the display. The buttons are programmable and
function as an integrated barcode scanner key or a numeric keypad Enter key. The Scan keys have
no effect on scanners tethered to the MX3X. 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 marked “Field Exit”).
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 - scanner is inactive.
The MX3X 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.
Button Settings
To edit the button parameters, select Start | Settings | Control Panel | Scanner . Change the
parameter values and tap OK to save the changes.
The default setting for the right button is Enter. The default setting for the left button is Scan.
When the MX3X 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)
Note: Not to be confused with the process the system administrator can use to create Custom
Key Maps for the MX3X keyboard. See Appendix A “Keymaps”, section titled “Creating
Custom Keymaps for the MX3X”.
