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

RS232 protocol

 

RFID Reader  RS232 Serial Data Format Rev 1.012-11-08

 

Serial port settings:

Baud rate :9600

Data bit    :8

Parity       :none

Stop bit    :1

 

 

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

 

 

STX	DATA										CHECKSUM		CR	LF	ETX
02	30	30	31	32	33	34	35	36	37	38	30	34	0D	0A	03
