Abstract

PURPOSE:To surely cause a LAN controller to rise by installing an operating section for setting parameter to the LAN controller and setting parameters by using the above-mentioned operating section before the LAN controller is caused to rise. CONSTITUTION:When a LAN controller 5 is installed or replaced with another, initializing parameters corresponding to the LAN to be connected are set by operating each switching element of dip switches 7a and 7b. When firmware is loaded/started by making the power supply, initialization is immediately started in accordance with the parameters set through the dip switches 7a and 7b by means of an initializing command. Therefore, when the parameters are once set at the beginning, setting of parameters by users usually becomes unnecessary and impossibility of the rising of the LAN controller 5 due to a wrong input, destruction of a file, etc., can be eliminated.

Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a parameter for setting parameters such as initialization information for a LAN control device that connects a computer to a local area network (hereinafter abbreviated as LAN). This is related to the setting method.

[Conventional technology]

FIG. 3 is a simplified configuration diagram showing the parameter setting method of a conventional LAN control device. In the figure, 1 is a keyboard 2.
．． Floppy disk device 3. A host computer is connected to a magnetic disk device 4, etc., and 5 is a LAN control device connected to a channel of the host computer 1 and a connector 6a on a LAN transmission line 6, which includes a controller, an encoder/
It consists of a decoder, a transceiver, etc., and controls protocols and connects the host computer 1 physically and logically to the LAN. When starting up the LAN control device 5, it is necessary to set various initialization parameters according to the LAN specifications such as frame length, and the user inputs these parameters directly into the host computer 1 from the keyboard 2. Alternatively, by storing the parameters in advance as a file on the floppy disk device 3 or magnetic disk device 4 and reading them into the host computer 1, the host computer 1 can perform °L A N i! Initialization parameters are set in the I control device 5, and the LAN control device 5 can be started up.

FIG. 4 shows a sequence of startup and initialization of a LAN control device according to the conventional method. That is, the LAN1# control device 5 is initialized after power-on (step 1) and firmware loading/starting (step 2), but requires input of parameters for this purpose (step 3). After inputting parameters using the keyboard 2 or the like, initialization (step 4) is performed. This enables communication between computers connected via LAN.

[Problem to be solved by the invention]

The conventional parameter setting method is as described above, but since it is necessary for the user to manually set the parameters each time the LAN control device is started up, the user has to memorize various parameters accurately or set the parameters in advance. It is necessary to create a file for the LAN controller, and if the parameters are entered incorrectly or the file is destroyed, the LAN control device cannot be started up.Therefore, in such a case, I had to call in a specialist to start it up and initialize it.

This invention was made to solve the above-mentioned problems6, and its purpose is to provide a parameter setting method that allows easy startup of a LAN control device without requiring keyboard input or files. shall be.

[Means to solve the problem]

A parameter setting method for a LAN control device according to the present invention includes a parameter setting operation section provided in the LAN control device;
Prior to starting up the AN control device, the parameters are set using the operation section.

[Effect]

In this invention, when installing or connecting a LAN control device, the parameters can be set using the parameter setting operation section provided in the LAN control device itself, so that a file for the parameters can be prepared and It is no longer necessary to perform keyboard input each time the LAN control device is started up, and the LAN control device can be started up easily and reliably.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a simplified configuration diagram showing a parameter setting method according to this embodiment, and the same reference numerals as in FIG. 3 indicate the same or corresponding parts, and the explanation thereof will be omitted.

In the figure, 7 is a parameter setting operation unit provided in the LAN control device 5 according to the present application, and is composed of 7a and 7b. The dip switch 7a.

7b is a LAN control device 5 on which LSIs such as controllers, encoders/decoders, transceivers, etc. (not shown) are mounted, and is fixed and attached on a board 5a connected to a cable 6b from a LAN transmission line 6 with a connector 6C. Each switch element is connected to a corresponding parameter input terminal of the LSI.

Next, the operation will be explained. First, when installing or reconnecting the LAN control device 5, set the initialization parameters according to the specifications of the LAN to be connected to the dip switches 7a and 7b.
The settings are made by operating each switch element of 9.
Thereby, startup and initialization of the LAN control device 5 are performed in the sequence shown in the flowchart of FIG.

First, turn on the power (Step 1) and load/start the firmware (Step 2).

After that, in the conventional method, it was necessary to input initialization parameters via the host computer from the keyboard 2, etc., but with this method, the manual input of such parameters is no longer necessary, and the initialization command immediately allows the deep switch to be input. ?
Initialization (step 3) is performed based on the parameters set in steps a and 7b. Therefore, by simply setting the parameters once at the beginning, there is usually no need for the user to set the parameters, and it is no longer impossible to start up the LAN control device 5 due to input errors, file destruction, etc.

In the above embodiment, the parameter setting switch 7
Although a and 7b are shown fixedly attached to the substrate 5a, they may be replaceable. An advantage of this case is that it is possible to flexibly respond to changes in the number of parameters.

〔Effect of the invention〕

As described above, according to the present invention, the LAN control device is provided with a parameter setting operation section, and the parameters are set using the operation section prior to starting up the LAN control device. This has the effect of making it easy and reliable to start up the two-control device.
