Abstract
PURPOSE: To enable to polling communication from CPU to the terminal side or from this unit to the terminal side, by connecting CPU and the terminal side or this unit and the terminal side through the selection of transmission data.
CONSTITUTION: The selection control circuit 5 selects the transmission data signal and accompanied signals to the serial parallel conversion circuit 2 at CPU 6, serial parallel conversion circuits 3-1...3-n at terminal side and terminals 7-1...7-n, with the instruction of the basic control section. Further, the circuit 5 selects the transmission data signal and accompanied signals with the selection gate circuit 4, selects the transmission data and accompanied signals to the terminals 7-1...7-n, and makes connection from CPU 6 to the terminals 7-1...7-n or from this unit to the terminals 7-1...7-n. Thus, without increasing the processing ability of this unit, polling communication from CPu 6 to the terminals 7-1...7-n or from this unit to the terminals 7-1...7-n with good efficiency.
