Notice
1. Confirm the electric voltage (DC12V) and differentiate positive anode and cathode of power supply
2. When external Power is used, make sure sharing the power with Controller Box or using the same GND
3. When the distance between card reader and controller is more than 50m, please use Power Line with at least 1.5 square cm Dia, or using several parallel Network wires

STX

DATA

CHECKSUM

CR

LF

ETX

 
STX=02 hex
DATA=Card ID (10 ASCII characters), pad with leading zeros
CHECKSUM=least significant byte (LSB) of SUM of DATA bytes
CR=0D hex
LF=0A hex
EXT=03 hex
 
Example:
Card ID is 12345678
As it is < 10 digits, pad with leading zeros so => 0012345678
DATA = 30 30 31 32 33 34 35 36 37 38
SUM of DATA = 30 + 30 + 31 + 32 + 33 + 34 +35 +36 + 37 + 38 = 0204
Checksum = LSB of 0204 = 04
 
So the serial output packet (hex format) is
02 30 30 31 32 33 34 35 36 37 38 30 34 0D 0A 03
