Serial port intercommunication agreement | VI-88TR development handbook
2 Serial port intercommunication
agreement
2 ways for application development:
1. Use control code of serial port communication agreement to operate
reader directly.
2. User matched SDK software with reader to call API function to operate
reader.
2.1 Summarize
In RFID application system, reader is connected with controller (PC) via
RS232 port, and receives commands from controller, then returns the result
of command execution. Therefore, we name Data Communication Packet
from controller to reader, to be Command Packet, and name that from
reader to controller, to be Return Packet.
2.1.1 Command packet format without address
BootCode Length Command Command Param
CheckSum
See chart above , command packet is composed of 5 parts:
Length(byte) Description
BootCode
1
Fixed to be 40H
Length 1
Effective length. The length is total bytes of
lateral 3 parts
Command 1 Command code
Command
Param
uncertain
Command parameter, length is changing with
command
CheckSum 1
Checksum, is all bytes from bootcode to
command param, discard patch code
