摘要

PURPOSE: To realize multi-purpose application for the radio equipment such various module function tests and a wide range of service by providing a control unit, a transceiver unit, a programmable software and a connection medium making 2-way communication available. CONSTITUTION: In the automatic diagnostic check, each of 12 function modules generates a fault signal when any module function is incomplete. A microprocessor 9 in a transceiver unit monitors the modules at a periodic interval programmed in advance and gives status information of a logic fault signal to a microprocessor 2 in a control unit via a digital serial interface bus 11 when the microprocessor 9 detects the fault signal. A microprocessor 2 stores the detected fault in a memory 5 and displays it onto a control panel display section 4 for its inspection and when a sure fault state is in existence, a counter- action programmed in advance is executed.
