Serial Trigger Modes

Manual/Serial Trigger, Low Power

You can activate the imager either by pressing the trigger, or using a serial trigger
command (see Trigger Commands on page 12-4). When in manual trigger
mode, the imager scans until a bar code is read, or until the trigger is released.
When in serial mode, the imager scans until a bar code has been read or until
the deactivate command is sent. In serial mode, the imager 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 imager's trigger when
using serial commands to trigger the imager. Once the imager has timed out,
you can activate the imager 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.
Read Time-Out
Imager Power Time-Out Timer
Note: The Imager Power Time-out Timer option only applies to Manual/Serial
Trigger.
When there is no activity within a specified time period, the imager enters low
power mode. Scan the appropriate Imager Power Time-Out bar code to change
the time-out duration (in seconds).
