ZK-RFID102 UHF RFID Reader User's Manual V2.0

1. COMMUNICATION INTERFACE SPECIFICATION

The reader communicates with host (MCU

，

MPU

，

Controller) using serial communication interface RS232 or

RS485 and complete corresponding operation according to the host command. The communication parameter is

57600bps 1 start bit, 8 data bits, 1 stop bit without parity check bit. In the process of serial communication, the

least significant bit of one byte is transmitted first and the least significant byte of command data sequence is

transmitted first.

2. PROTOCOL DESCRIPTION

A communication procedure is sponsored by the host sending commands and data to the reader and the

reader returns the result status and data to host after command execution.

Reader receives a command executes a command, only the reader complete the implementation of a

command, to receive the next command. During the implementation of the command in the reader, if sending

commands to the reader, the command will be lost.

The following table shows the process of the host computer command:

HOST

DIRECTION

READER

Command Data Block

→

The interval between two consecutive bytes in the command data block should be less than 15ms. During

command data block sending, synchronization will lost if the host receives any data from the reader and the host

should stop command sending and restart the communication after 15ms.

The reader completes command execution in inventory ScanTime (not including host sending data time)

except inventory command after receiving host command and returns the results. During the period, it doesn’t

process any host data. The feedback of command execution results is as follows:

READER

DIRECTION

HOST

Command Data Block

→

The interval between two consecutive bytes in the response data block should be less than 15ms.
