PURPOSE:To attain efficient remote control of terminal devices, by assigning an address other than addresses possible for setting in a decimal number to a terminal device fixed at the production of the address. CONSTITUTION:Address data in 8-bit are inputted to address set terminals of AD1-AD8, and binary signals of digital switches in hexadecimal number corresponding the lower-order 4-bit and the upper-order 4-bit to each one digit respectively are inputted to the terminals AD1-AD8. The address of a control terminal device 3 changing the address according to the state of use is assigned to the address to be represented in the same number as that in decimal number. Address set switches SW1, SW2 comprising digital switches in decimal number are connected to the terminals AD1-AD4 and AD5-AD8 respectively to set the address corresponding to the expression in decimal number. The addresses represented with the rest hexadecimal number are assigned to the terminal devices 3 corresponding to a sub-operation panel and the like not requiring any change and these addresses are set fixedly. |
