Image Scanner Trigger Modes

You can activate the image scanner either by pressing the trigger, or using a
serial trigger command (see
"Trigger Commands" on page 10-4). When in
manual trigger mode, the image scanner scans until a barcode is read, or until
the trigger is released.
When in serial mode, the image scanner scans until a barcode has been read or
until the deactivate command is sent. In serial mode, the image scanner can
also be set to turn itself off after a specified time has elapsed (see
Read Time-
