及び伝送路を用意することを必要とした。 In pulse code type remote monitoring and control equipment, many early devices used long and short codes for signal transmission and reception between the master station and the slave stations, but recently, equal length codes have come to be used. Therefore, in order for a single master station to exchange signals with multiple slave stations with different pulse code formats or with multiple types of signal formats, the master station must use a dedicated transmitter/receiver for each slave station according to the code format of the slave stations. It was necessary to prepare equipment and transmission lines.

The timer control circuit 2 obtains transmission data Db converted into RZ length/shortness codes corresponding to each bit of the serial data B as shown in FIG. 2b. These data D a , D b
is switched by a transmission switching circuit 3, and sent onto a transmission path by a transmitter 4 such as a modem. The transmission switching circuit 3 generates a transmission switching signal adapted to a pulse code format that can be received by the slave station or master station to which the data is transmitted.
Data D a or D b is switched and outputted by DX. This transmission switching circuit 3 is specifically realized by a circuit as shown in FIG. One of the AND gates G 1 to which data D a is input and the AND gate G 2 to which data D b is input is opened depending on the logic state of transmission switching signal DX. The data output of one of the gates G1 and G2 is switched to the transmitter 4 through the OR gate G3 . On the receiving side, both types of data are discriminated and processed based on the difference in their encoding formats.
