1.3.2 Scan engine interface without decoding
Interface circuit is a ZIP (0.5mm-8p) interface which communicates with outside world.
It’s the microprocessor that controls the scan engine’s work and takes the data to
decode.
Pin NO.

SOS
Scan starting signal:
When the laser line reaches the edge, the signal will
transform from high to low or from low to high in order
to detect the start and finish of a scan.
4
DATA
The width of the DATA signal stands for the width of
black and white bars. The output is CMOS level.
High level=Bars, Low level=Spaces
5
TRIG
Allowing Trigger scanning signal:
TRIG=High: The scan engine will enter a power-saving
mode;
TRIG=Low: The scan circuit will be activated to the
ready state.
6
LASER-EN
Activation signal
LASER-EN=High or not connected: The laser will be
closed;
LASER-EN=Low and TRIG=Low: The scan engine
circuit will be activated and ready to scan barcodes. The
laser will open.
