DATA COMMUNICATION METHOD

摘要

PURPOSE: A data communication method is provided to check a control state and an undesirable state of a refrigerator control part by transmitting and receiving data. CONSTITUTION: The data communication method comprises the steps of: outputting a synchronization signal of a high level in order to output data from a micom(10) to a communication circuit(70) and transmitting the data in series (106); transmitting an ON input signal after transmitting the data(108); receiving the data in synchronism with the synchronization signal (118); transmitting a parity check signal for discriminating whether or not a signal error exists at the data communication (120); checking whether the parity bit is normal; and displaying the data when the parity bit is normal (124).
