Abstract

PURPOSE:To use only a desired device to operate the titled system without giving any effect to other devices even though the power supply of a device under an unused state is turned off, by providing a switch part which connects and disconnects a signal line. CONSTITUTION:Plural devices 3 are connected to a standard digital interface GPIB cable 4 to form an interface bus control system. A switch part 5 interlocks a power supply switch 6 of the device 3 and connects and disconnects a signal line of a GPIB bus connector part in response to ON and OFF of the switch 6 respectively. Therefore the signal lines between the part 2 and transceiver bus control parts 1A and 1B are cut simultaneously by the part 5. As a result, it is possible to operate the system only with a desired device without affecting other devices although a device having a turned-on power supply is connected to a device having a turned-off power supply via a GPIB cable 4 and through the connector part 2.

ランシーバ・バス間の接続方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a standard digital interface bus control system, and particularly to a method of connecting between a transceiver bus and a connector section of each device constituting a system.

〈従来技術〉 標準ディジタル・インターフェイス（以下ＧＰ１Ｂイン
ターフェイスという）機能を持っている装置でシステム
を構成する場合、以下に述べるような動作設定を行なう
。<Prior Art> When a system is configured with devices having a standard digital interface (hereinafter referred to as GP1B interface) function, the following operational settings are performed.

方すスナの方はトーカから送られてくるデータを受信す
る、 によってデータの送受を行なう。When trying to operate a system by connecting multiple devices with GPIB interface functions, you must: ・ Set each device as a controller, talker, or listener and operate it with each function. (There is only one device in the system), but it performs talker or listener settings for other devices connected to the GPIB bus. In some cases, a device with a controller function can communicate with other devices. Initialize the system configuration on the condition that the controller function can be transferred, and then: ・ The talker sends data to the listener, while the listener receives the data sent from the talker. Data is sent and received using .

ログラムする必要がある。In this way, when a system is constructed by connecting a plurality of devices equipped with GPIB interfaces, it is necessary to program each device to have a controller, talker, or listener function depending on the purpose of use.

不都合な点があった。However, when assembling a system, when there are devices that do not require data transmission and reception, all devices in the system are connected with GPIB cables, so the frequency of signal level drop or noise pickup of the cables is low. Therefore, there is an inconvenience in that devices connected by cables must be powered on regardless of whether they are being used or not.

The present invention provides a GPIB interface bus control method that allows the system to be operated with only the necessary devices without causing any trouble to other devices.

〈実施例〉 以下図面に従って本発明の一実施例を説明する。<Example> An embodiment of the present invention will be described below with reference to the drawings.

チ部５を設けている。FIG. 2 is a block diagram showing details of the main parts of the device 3. G
A switch section 5 for connecting/disconnecting the signal line is provided between the signal line of the PIB bus connector section 2 and the interface transceiver bus control sections IA and IB of the device l connected thereto.

このスイッチ部５は装置３の電源スイ・ノチ６と連動す
るものであり、電源スィッチ６がオンされれば信号線を
接続し、オフされれば切断される。This switch section 5 is interlocked with the power switch 6 of the device 3, and when the power switch 6 is turned on, the signal line is connected, and when the power switch 6 is turned off, the signal line is disconnected.

号線が切断される。With the above-described configuration, even if a certain device 3 in the system becomes unused and is turned off (power switch 6 is turned off), the switch section 5 simultaneously connects the GPIB bus connector section 2 and the transceiver bus. The signal line between control units IA and IB is disconnected.

のみでシステムの運用を可能とすることができる。As a result, even though the device whose power is turned off is in the state where the GPIB bus connector section 2 is connected to the device whose power is turned on by the GPIB cable 4, it cannot be connected to other devices. The system can be operated with only the necessary equipment without any hindrance.

The system can be operated by connecting only these devices with GPIB cables, and devices that are powered off will not adversely affect the operating system.

る利点があり、有用である０In addition, even if a large number of devices are connected in this way, you can reduce power consumption and connect devices freely by simply turning on the power to the devices as needed. It is useful because it eliminates the need for unnecessary operations such as connecting and disconnecting the connector.
