Manual Trigger - Enhanced
Serial Trigger
You can activate the scanner either by pressing the trigger or using a serial
trigger command (see Trigger Commands on page 184). You must be in a serial
interface mode in order to use serial triggering. Refer to RS232 Serial Port (page
7) or USB Serial (page 9)
for further information. When in serial mode, the
scanner scans until a barcode has been read or until the deactivate command is
sent. The scanner can also be set to turn itself off after a specified time has
elapsed (see Read Time- Out, which follows).
Read Time-Out
Use this selection to set a time-out (in milliseconds) of the scanner’s trigger when
using serial commands to trigger the scanner. Once the scanner has timed out,
you can activate the scanner either by pressing the trigger or using a serial
trigger command. After scanning the Read Time-Out barcode, set the time-out
duration (from 0-300,000 milliseconds) by scanning digits from the
Programming Chart, beginning on page 211, then Save.
Default = 30,000 ms.
Presentation Mode
Presentation Mode uses ambient light and scanner illumination to detect
barcodes. When in Presentation Mode, the LEDs remain dim until a barcode is
presented to the scanner, then the aimer turns on and the LEDs turn up to read
the code. If the light level in the room is not high enough, Presentation Mode may
not work properly.
Scan the following barcode to program your scanner for Presentation Mode.
