Field Exit Key Function (IBM 5250/TN5250 Only)
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.
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 device’s Scan buttons.
Note: Refer to the MX3X Reference Guide before programming the Scan / Enter buttons. The
Reference Guide also contains instructions for the Key Map Utility for the keypad.
