<p>PURPOSE:To improve the workability of maintenance of a system and to reduce the cost, by transmitting data between devices only when a main and a subdevice are connected for a prescribed time or more, without using a special connector. CONSTITUTION:Interlocking lines 5 and 7 are connected for a main device 1 side and a subdevice 3 side at the mounting of connectors 2A and 2B. When the connectors 2A and 2B are connected, an interlocking signal is transmitted to the main device side from the subdevice 3 in the path of interlocking line 7 pin 12 pins 9 and 10 pins 13 and 14 pin 11 interlocking line 5. A time 4 provided to the main device 1 is started with an interlocking signal transmitted via the interlocking lines 5 and 7. The data transmission/reception between the main device 1 and the subdevice 3 can be made only when the connectrs 2A and 2B are connected for a set time of a timer 4 or more.</p> |
