Trigger Modes
Manual Trigger
In manual trigger mode, the scanner scans until a barcode is read, or until the scan
trigger is released. Two modes are available, Normal and Enhanced. Normal mode
offers good scan speed and the longest working ranges (depth of field). Enhanced
mode will give you the highest possible scan speed but slightly less range than
Normal mode. Enhanced mode is best used when you require a very fast scan
speed and don’t require a long working range. Default = Manual Trigger Normal.
LED Illumination - Manual Trigger
If you wish to set the illumination LED brightens, scan on e of the barcodes below.
This sets the LED illumination for the scanner when the trigger is pressed. Default =
High.
Note: The LEDs are like a flash on a camera. The lower the ambient light in the room, the
brighter the LEDs need to be so the scanner can “see” the barcodes.
Read Time-Out
Use this selection to set a time-out (milliseconds) of the scanner’s trigger when
using the 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 on the Programming Chart, then
scanning Save. Default = 30,000ms.
