- Error Check
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.
