Serial Trigger Modes
Manual/Serial Trigger, Low Power
You can activate the image scanner either by pressing the trigger, or using a
serial trigger command (see
Trigger Commands on page 12-4). 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-Out
(Serial Trigger Mode) , which follows).
Read Time-Out (Serial Trigger Mode)
Use this selection to set a time-out (in milliseconds) of the image scanner’s
trigger when using serial commands to trigger the image scanner. Once the
image scanner has timed out, you can activate the image 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 on the Programming Chart inside the back cover, then scanning
Save . Default = 30,000 ms.
Image Scanner Power Time-Out Timer
Note: The Image Scanner Power Time-out Timer option only applies to Manual/
Serial Trigger.
When there is no activity within a specified time period, the image scanner enters
low power mode. Scan the appropriate Image Scanner Power Time-Out
barcode to change the time-out duration (in seconds).
