Installation
To install the device, perform the following steps:
Connect the device with your computer through a serial cable directly and via the USB-A connector (for power supply only). The device will start up and the LED turns into red which means standby.
Open the device manager of your computer. If the device appears and “COM” port is displayed, the connection was successful.
Open the output of the computer software, such as the “Serial debug assistant”.
Put tag on the top of the reader. The software will output data of the tag (card number). When reading the tag, the LED light changes from red to green. The device will automatically read every second.
RS232 communication
9600 bps, none parity, 8 data bits, 1 stop bit
Data format
STX | Length | CardType | SNR [0..N] | BCC | STX |
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) |
Card type | 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 02 06 00 8E 6D 5D B0 03
STX: 02
Length: 0A, 9 bytes
CardType: 02, EM
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
Note the following precautions:
Do not install the reader on magnetic or magnetic shielding objects and metal objects. They would affect the RF signal.
If the tag is still in the induction zone after reading, the RF reader will not send data and there will be no system information about this.
Troubleshooting
Note the following common setup problems and how to fix them:
Operation without feedback
Try the following steps to fix the issue:
Ensure that the interface is plugged in.
Check whether the tag is valid.
Ensure there’s no other RF tag within reading range.
Data error
Try the following steps to fix the issue:
Check whether the mouse has moved.
Check if the reader is in a critical state.
Check whether the cable length is too long.
