Scanner Trigger Modes
Manual/Serial Trigger, Low Power
You can activate the 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 scanner scans until a bar code is read, or until the trigger is
released.
When in serial mode, the scanner scans until a bar code has been read or until
the deactivate command is sent. In serial mode, the 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 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 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 = 300,000 ms.
Scanner Power Time-Out Timer
Note: The Scanner Power Time-out Timer option only applies to Manual/Serial
Trigger.
When there is no activity within a specified time period, the scanner enters low
power mode. Scan the appropriate Scanner Power Time-Out bar code to
change the time-out duration (in seconds).
