A check code may be used by the terminal or the server to distinguish whether the received information is error or not. To prevent errors occur during data transmission, error check is added to against data misoperation, so as to increase the security and efficiency of the system. The check code is generated by the CRC-ITU checking method.
The check codes of data in the structure of the protocol, from the Packet Length to the Information Serial Number (including “Packet Length” and “Information Serial Number”) , are values of CRC-ITU.
CRC error occur when the received information is calculated, the receiver will ignore and discard the data packet.
Fixed value in HEX 0x0D 0x0A.
The commonly used information packages sent by the terminal and those sent by the server will be interpreted separately.
Login Message Packet
The login message packet is used to be sent to the server with the terminal ID so as to confirm the established connection is normal or not.
