Abstract
PURPOSE: To avoid mis-reception, by performing the signal level automatically, through the provision of signal level compensation circuit with each slave station, the compensation of reception level of slave station based on the signal delivered from the master station by this circuit, and the compensation of signal level from the slave to master station.
CONSTITUTION: In the multi-drop type system connecting the master station 11 and a plurality of slave stations 12-1, 12-2... with the delivery lines 13, the slave stations are provided with the transmitter 200 at slave station side and the receiver 100, allowing to receive the signal delivered from the transmitter 300 at master station with the slave stations 12-1, 12-2... at the same time, and to receive the signal from the slave stations with the master receiver 400. The circuit 200 with this constitution is provided with the variable circuit 202 to keep constant approximately the output of the unipolar and bipolar converter 203, the circuit 100 is provided with the variable circuit 102 to keep constant the output of the floating transformer 101, allowing to automatically compensate the reception and transmission level based on the signal from the master station 11.
