Email info ctiautomation net 3 4 CRC 16 3 4 1 Overview of the CRC 16 The CRC cyclic redundancy check is a system to confirm whether there is any error in the communications frame during data transmission The CRC is among the most effective error check systems The transmission station calculates and adds CRC data to the last block of the frame and the receiving station also calculates CRC data against the data received and compares them with each other Steps to calculate CRC data Divide data expressed as a polynomial for example 0000 0001 0000 0011 0000 0011 0000 0010 0000 0000 0001 0100 the 48 bit data shown in Section 3 4 3 Calculation example XE KEK EK EK EX EX X by a generative polynomial expression 17 bits x X X 1 CRC data is the remainder 16 bits of this division Ignore the quotient and send a message with the remainder added to the final two characters of the data The receiving station divides this message with the CRC added by the generative polynomial expression and considers the transmitted message to have been received without any error if the remainder is 0 CRC 16 The generative polynomial expression is expressed as a multiplier of X such as X X 4 in place of the description of binary code 1101 Although any prime polynomial expression is acceptable as the generative polynomial expression some standard generative polynomial expressions for optimizing error detection are defin
