Abstract

PURPOSE:To eliminate necessity to remove a cable from a device, which goes to be a kernel, and to fit it again each time a connecting subject device is different by connecting a device having an interface different from the device, which goes to be the kernel with the same cable. CONSTITUTION:An information processor 2 includes a connector 3 and a switch for interface change-over and a MODEM 6 including a connector 5 is connected by a cable 1. The connector 3 is connected through a switch 4 to an interface circuit, which correspond to the MODEM 6, in the information processor or connected to another information processor 8 by the same cable 1 by switching an interface with the switch 4. In such a case, the switch 4 introduces the cable 1 to the interface circuit in the information processor 2 to correspond to the other processor 8. On edge of the switch 4 is connected through the connector 3 to the cable 1 and the two couples of the other edges are respectively connected to the interface which corresponds to the other information processor 8.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an inter-device cable connection method, and particularly to a method for exclusively connecting one device to a plurality of devices having different interfaces using a cable.

[Conventional technology]

In this type of conventional device-to-device cable connection method, one core device, for example, an information processing device, is equipped with interface circuits for each type of device to be connected, and a connector and a counterpart device corresponding to each interface circuit are provided. A cable was used to connect the two connectors.

[Problem that the invention seeks to solve]

In the conventional method described above, even if the cables have the same connector, a corresponding number of cables are required if the interfaces between the devices are different, and each time the device to be connected is changed, the cable must be removed from the information processing device. The disadvantage is that you have to reattach the cable.

[Means for solving problems]

The system of the present invention is a system in which one nuclear device is exclusively connected to multiple devices with different interfaces by cable, and the nuclear device is provided with a switch having a switching position corresponding to the device, and the - The device is characterized in that one end is connected to a cable and the other end at each switching position is connected to an interface circuit corresponding to the device built in the nuclear device, thereby making it possible to connect devices using the same cable.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention.

FIG. 1(a) shows that an information processing device 2 having the functions of the present invention, which includes a connector 3 and an interface switching switch 4, and a modem 6, which includes a connector 5, are connected by a cable 1. .

The connector 3 is connected via a switch 4 to an interface circuit (not shown) compatible with a modem 6 in the information processing device 2 .

Further, FIG. 1(b) shows that by switching the interface with the switch 4, the information processing device 2 and another information processing device 8 can be connected with the same cable 1 shown in FIG. 1(a>). In this case,
The switch 4 guides the cable 1 to an interface circuit (not shown) in the information processing device 2 that corresponds to another information processing device 8 .

One end of the switch 4 is connected to the cable 1 via the connector 3, and the other end of the switch 4 has two sets, one set is connected to the modem 6.
The other set is connected to a corresponding interface circuit, and the other set is connected to an interface circuit corresponding to another information processing device 8. Further, connections between the switch 4 and each of the above-mentioned interface circuits include the information processing device 2, the modem 6,
This is done to absorb differences in interfaces with other information processing devices 8.

〔Effect of the invention〕

As explained above, the present invention allows devices with different interfaces to be connected to one core device using the same cable, so each time the connection target design changes, the cable can be removed from the core device and changes can be made. This has the effect of eliminating the need to reconnect cables for devices that have been used.
