Description

STX

1

0x02, the starting of a data packet.

Length

1

Length of the data bytes in the packet (except STX).

CardType

1

0x01: Mifare; 0x02: EM4100

SNR [0..N]

5

SNR[0]:batch number, SNR[1..4]:serial numbers

BCC

BCC = Length xor CardType xor SNR[0..N]

STX

1

0x03, the ending of a data packet.

Example:  02 0A 01 06 00 8E 6D 5D B0 03

STX: 02

Length: 0A9 bytes

CardType: 01, MF

SNR: 06 00 8E 6D 5D, 06 = batch number, 00 8E 6D 5D = 0009334109 (DEC)

BCC: B0,  B0 = 0A xor 02 xor 06 xor 00 xor 8E xor 6D xor 5D

EXT: 03

 Precautions

1. Do not install the reader on the magnetic objects and metal objects, they will seriously affect the RF signal.

2. If after reading, the tag is still in the induction zone, the RF reader will not send data and without any hints.

 Common problems

1. Operation without feedback: Please check whether the interface plugged in, whether the tag is a valid or whether another RF tag is within the reading range.

2. Data error: Please check Whether the mouse is moved, whether the reader is in a critical state and whether the cable length is too long.
