PURPOSE:To secure an effective application to the interface of the multiple kinds and minor production by producing the parity signal and the parity bit signal in the transmission data and then giving a comparison between the pairty signal and the parity bit in the transmission data. CONSTITUTION:Serial-parallel conversion circuit 1 converts the serial data into the parallel data, counter circuit 3 sets the bit length of the reception data, and the clock pulse is generated from clock circuit 4 in relation to circuit 3. Parity circuit 5 produces the parity signal from the transmission data and compares 6 the parity signal with the parity bit in the transmission data. Then the parallel data sent from the transmission system is supplied to circuit 1 in response to the output of circuit 3, and at the same time the data is led to circuit 5 to produce the parity signal. This parity signal is then compared 6 with the parity bit in the transmission data. Thus an effective application is secured to the interface of the multiple kinds and minor production. |
