Serial Trigger

You can activate the scanner either by pressing the trigger, or using a serial trigger
command (see

Trigger Commands

on page 228). You must be in a serial interface

mode in order to use serial triggering. Refer to

RS232 Serial Port

(page 14) or

USB

Serial

(page 16) for further information. When in serial mode, the scanner scans

until a barcode has been read or until the deactivate command is sent. The scanner
can also be set to turn itself off after a specified time has elapsed (see

Read Time-

Out

, which follows).

Read Time-Out

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

barcode, set the time-out duration

(from 0-300,000 milliseconds) by scanning digits from the

Programming Chart,

beginning on page 289, then

Save

.

Default = 30,000 ms.

Trigger Mode 11

Trigger Mode 11 provides an option for improved barcode targeting control. When
activated, this enables the user to squeeze the trigger to activate only the aimer for
precise targeting, then release the trigger to scan the selected barcode. Combined
with

Single Code Centering

, this can improve performance for scanning specific

barcodes in regions with many barcodes present, or for precisely selecting and
scanning barcodes at a distance.

Aimer will be pre-lit when trigger is pressed and scanning occurs when trigger is
released until a good scan or normal scan timeout.

TRGMOD0 is the Default.
