Adjust the settings and tap the OK box to save the changes. The changes take effect immediately.
When Power Port 1 while asleep is checked, whichever serial port is enabled as Port 1 will
remain powered while the device is in Suspend, at the cost of reduced battery life. This allows a
tethered scanner to wake the device by pressing the trigger on the scanner.
When Send Key Messages (WEDGE) is checked any data scan is converted to keystrokes and
sent to the active window. When this box is not checked, the application will need to use the set of
LXE Scanner APIs to retrieve the data from the scanner driver. Note that this latter method is
significantly faster than using “Wedge”. Even if Send Key Messages is enabled (“key mode”), the
data is still available using the scanner APIs (“block mode”). When using the scanner APIs, refer
to the “CE API Programming Guide” and the ClearBuf setting. When two applications are reading
the data using block mode, ClearBuf must be off so that the data is not erased when read.
Note: The user can also open the WDG: device and perform standard OS read functions to
retrieve the data without using the LXE APIs.
When Enable Internal Scanner Sound is checked, the functionality of the internal scanner driver
engine includes audible tones on good scan (at the maximum db supported by the speaker) and
failed scan. Rejected barcodes generate a bad scan beep. In some cases, the receipt of data from
the scanner triggers a good scan beep from a tethered scanner, and then the rejection of scanned
barcode data by the processing causes a bad scan beep from the MX3X on the same data.
