AUDIO FREQUENCY ELECTRICAL JOINT APPARATUS WITH A UNIT FOR COMPARING A SIGNAL, CAPABLE OF ALLOW A CONTROL ROOM TO FIND OUT A CAUSE AND POSITION OF AN ERROR RAPIDLY

摘要

PURPOSE: An audio frequency electrical joint apparatus with a unit for comparing a signal is provided to detect signal distortion and abnormal modulation in interfacing a signal by monitoring a signal between a card and a CPU.;CONSTITUTION: A CPU(52) is installed inside a rack apparatus(50) and determines an output position of a signal transmitted from the PC. A plurality of signal cards receives a signal from the CPU and generates a frequency in a predetermined band. The CPU in the signal card receives a signal transmission command from the CPU of the rack apparatus and transmits the signal to a transmission unit. The transmission units receive the signal transmission command and transmit it to another neighboring rack apparatus.;COPYRIGHT KIPO 2010
