Inghua embedded PC development-Remote Access Gateway Machine

In the domestic industrial control field, Yan Hua is in the leading position. Generally, CSG (embedded PC) is used for data collection. Here we use the wince5.0 operating system platform as an example (Other include wince6.0 and Linux ).

1. First, you must have the following equipment and software

(1) Device

Yan Hua fan-less industrial computer dc24v/12 V switch power supply network router crossover network cable notebook (PC) (2) software diaganywhere (PC version, provided by Yan Hua)

Diaganywhere (wince version, provided by Yan Hua) netgate folder (gateway machine software and related files, self-developed) sqlce database generation software (createcems, self-developed) (PC supports software installation) wince remote debugging tool (which can be downloaded online and placed on the gateway) 2. Run diaganywhere

After the electrical connection is complete, right-click Device on LAN and then click Search the LAN

Because no network IP address is configured for the new network to shut down, after DHCP fails to be searched, the default IP address will be used as the IP address under the Cross network cable, and the IP address will be set on the PC: 192.168.1.2 use the vro condition, the allocated IP address is automatically obtained under the Cross network cable condition. When the network cable is connected, it may not be searched for a period of time. The result will be displayed, as shown in Figure 2. The cross network cable is searched (169.254.x.x)

If you click the gateway machine you found (no password by default, you can directly OK), the connection will fail. Wait until the window is displayed and right-click the gateway to shut down.

Then left-click the ticket

Network Setting

 

In the displayed dialog box, select specify an IP address and enter the network IP address.

If the site has a fixed IP address, you must set it to the same IP address segment on the local machine, and enter the IP address according to the fixed IP address information (configuration document, 192.168.1.244 by default) after configuring the network information of the gateway machine, you can directly search for the gateway machine in diaganywhere when using the vro network connection. You can directly log on to the gateway machine in the remote desktop mode and perform operations directly.

Only one gateway machine can be connected to a vro. Otherwise, after an IP address is automatically assigned, the gateway machine cannot be distinguished. 3. In the final result, diaganywhere can find the gateway. Diaganywhere remotely accesses the gateway. Do not set a password. (enter the password every time. I think it is too cumbersome ). Go to the gateway machine page and enter the gateway machine. Note: 1. the embedded PC is similar to the embedded PC, which can be connected to the display, mouse, and keyboard. However, the embedded PC works on site and the on-site environment is complex. You cannot bring a monitor to the debug gateway. Therefore, using the Remote Desktop tool is both convenient for debugging and development. 2. Some of the gateway machine's built-in "diaganywhere" server will not start automatically. In this case, you must first configure the "Telnet" and "ftp" of the gateway machine so thatThe "diaganywhere" server starts. And then useThe "diaganywhere" client operates on the gateway, andThe "diaganywhere" server can be set to automatically started. 3. Because Configuring telnet requires the IP address of the notification network shutdown, and the cross-network method, the gateway address must be set"Diaganywhere" software.The "diaganywhere" client software cannot find the server on the gateway machine (the server will not start automatically ). Therefore, you can only use a router to connect the PC and the network to the Gateway. At this time, the router will allocate the IP address to the gateway machine and then view the route (the device name of the gateway machine is generally "00 -") obtain the address of the gateway. 4."Diaganywhere PC client software can be downloaded from the official website of Yanhua.
