1.3 Interface specifications
All Winson readers can be equipped with USB Keyboard, TTL/RS232 (DB9 female),
RS485 (DB9 male), PS2 keyboard or any other customized interfaces. Different
product’s standard interface is different. So please confirm it before purchase. Other
interfaces can be customized according to customer’s demand.

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. Pin Name Description
1、2 GND Ground
3 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.
7 IR-TRIG Optional, IR trigger pin, only for WSL3000

When pin 1 receives low level for 10ms, it means trigger and scan. (optional)
Pin 6 is only used in trigger mode. It will output low level for 100ms if it detects no
barcode after trigger. (value added service)

2. Command instructions
2.1 Barcode command instructions
A. Command barcodes are printed via Code 128 CODE B barcode set. Command
barcode is same as serial port command value（Detail as Chart 2.2-1）.
B. Note with “*” means factory default parameter.
(a) “%SET”: Enter setting mode; It will drop out setting mode automatically if it not
scans next command barcode in 30s;
(b) Modify parameters command: It can scan one or several command barcodes;
(c) “%END”: Save & Exit.

Note:
1. Check Sum: Radix complement of command sum, high byte in the beginning and
low byte in the end.
Check digit calculation method: Adding up all bytes to get sum before checking
(excluding two check digit bytes). Check digit value=Sum reversed as per digit then
add one.
Example: Save & Exit (0A 04 31 00 24 25 45 4E 44 FF) adding up to obtain the
sum: 02 5E, switch to binary (0000 0010 0101 1110), then reverse (1111 1101 1010
0001), finally add one is check digit (FD A2).
2. When Command uses character in the following data format pack (prefix excluding
“0x”) and be sent via serial port command, it should switch character to Hex of ASCII
code accordingly.
