Abstract

PURPOSE:To use plural peripheral equipments through one interface by wiring the address and vector of a peripheral equipment to the connector of the peripheral equipment. CONSTITUTION:A connector 28 connected to the signal cable 29 of a printer 3 is inserted into the connector 27 of the printed board side of an interface connected to a bus 100. An address selection part 21 detects an address signal from a CPU to close a data gate 25, and a vector is inputted from a vector setting part 22 to the data 25 through a bus 102. Thus, the gate 25 is turned on to interrupt the CPU1 through a CPU bus 103, and a dta gate 26 is closecd to supply data from the CPU1 to a printer 3 through a data gate 26, a PS/SP conversion part 23, a transmitting and receiving circuit part 24, the connector parts 27 and 28, and the signal cable 29.
