Abstract

PURPOSE:To make change of group for a number of devices in group constitution in a short time very easily, by using a matrix circuit which can be connected to input terminals in any combination for a data gathering circuit. CONSTITUTION:In a diode matrix 60, input and output terminals can be connected in any combination by changing the installed position of diodes. Detectors 11, 12 are connected to an output terminal X1 and detectors 13, 14 are connected to an output terminal X2. This is the same for an output terminal X3. Thus, when status change detecting signal PD1 or PD2 for a device belonging to a group A is produced, the signal is also applied to a lamp drive circuit 100 to illuminate a lamp display 101. Thus, any type of group constitution can be made, by suitably changing the installed position of diodes only.
