Abstract

PURPOSE:To connect data communication of semi-duplex communication system using radio system to a transceiver of wired system by utilizing an adaptor having a means switching the radio transceiver from the reception to the transmission and vice versa depending on the presence of a carrier signal. CONSTITUTION:When a data from a data transceiver is transmitted to the adaptor 3 via an MODEM, a flip-flop 314 is triggered by an output of a carrier detecting circuit 31 and a receiving/transmission switching signal is outputted to a radio equipment. The transmission data is transmitted to an analog delay circuit 321 at the same time and outputted to a radio equipment in the transmission state after a time required for switching. The carrier detecting output is turned off at the end of transmission, the state is detected by a trigger circuit 312, a timer 313 is started and the flip-flop is reset after a prescribed time and the transmission/receiving switching signal is transmitted to the radio equipment.
