Ⅱ Instructions for use
Method of installation and use
1. Connect with computer through a serial cable directly. When the buzzer sounded, reader into the self-inspection. And the same time, LED turn into red means standby.
2. Open the output of computer software,such as Serial debugging assistant.
3. Put tag on the top of reader, the software will output a data(card number) of the tag. When reading the tag, LED light change from red to green.
Detecting device is connected
Ⅲ Communication Format
RS232 Communication
9600 bps, none parity, 8 data bits, 1 stop bit
Data Format
STX | Length | CardType | SNR [0..N] | BCC | ETX |
The following table describes the packet fields
Field | Length | 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 | 1 | 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: 0A, 9 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
Ⅳ 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.
Ⅴ 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.
