Title:
PROTECTING AND DETECTING METHOD FOR CABLE MISCONNEFCTION
Document Type and Number:
Japanese Patent JP3769986
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To make preventable an electronic system from a malfunctioning at a low cost by detecting cable misconnection without increasing the number of cores of a cable with connectors nor the number of pins of the connectors by mutually connecting reset signals and ground signals of a main device and an extension device and resetting the electronic system it the cable with the connectors is miswired between the main device and extension device.
SOLUTION: If the cable is misconnected from an extension device (1) in an extension device 2 to an extension device (2), since reset signal lines 2j and group signal lines 2k among signals lines between connectors 2b and 2c are cross-connected, the ground signal lines 2k are connected to the reset signal line 1f of the main device 1 and the reset signal line 2j of the extension device (1) and held at low level. Similarly, since the reset signal lines 2j are connected to the ground line 2k of the extension device (1) and held at low level. Reset signals are all active, so the system is held reset and prevented from malfunctioning.
