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 bar code is read, or until
the trigger is released.
When in serial mode, the image scanner scans until a bar code has been read
or until the deactivate command is sent. 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).
* Manual/Serial Trigger
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 bar code, 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.
Read Time-Out
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
bar code to change the time-out duration (in seconds).
Note: Scanning zero (0) is the equivalent of setting no time-out.
