Note:
1. Laser mode: This mode only supports specified laser scan engine.
Standard mode: This mode satisfies the scanning performance described in the
product specification.
High detection mode: It broadens the frequency characteristics of analog signal
processing and sets the detection range high at the same time. It is the highest
detection mode that improves scanning performance of hardly modulated barcodes
(meaning modulation of contrast within one barcode).
Low detection mode 1: It lowers the detection range and prevents the scanning
performance from degrading by noise. It mainly improves scanning performance of
low PCS and low resolution barcodes from the long distance.
Low detection mode 2: It narrows the frequency characteristics of analog signal
processing and sets the detection range low at the same time. It is the lowest detection
mode that improves blemished or heavily defective barcodes (meaning spots and voids
within the barcode).
2. Swing plate boot mode: This mode is used to control working status of laser head
swing plate via TRIGGER pin signal.
Trigger swing: Enable swing when trigger scanning barcode (TRIGGER low
level). Disable swing when turn off scanning (TRIGGER high level).
Power swing: It will swing continuously as long as the laser head is powered on.
（
TRIGGER low level).
