Appendix B. Upgrade Custom Web Pages

The NDC has a built-in web server, so the web contents are contained in Flash Memory, the same as software parts, allowed to erase and re-written. It provides an easy way to update the web pages -- just simply load and issue command from network (FTP and Telnet).

Caution: The update of content page is very sensitive to system operation; therefore, incorrect operation may cause system fail to response to any request. The following operations provided here are only for experienced system integrator. Remember that always consult to your distributor or dealer in advance to update the content.

The following procedures are to update the web page:

1. Clean up system

Before updating the pages, make the NDC back to factory default stage -- open the home page of NDC in your web browser, go into Configuration -> System -> System Information, click <Load Default> button, click <Apply> button, and then click <Reboot> button in configuration page. Keep the NDC in an idle state, which stops all video requests from other station.

2. Download complete web pages

For backup purpose, we should download the complete built-in contents before updating. The pages layout is described as below: z 3.0.0/WWW: Main video pages including static HTML pages and JAVA applets. z 3.0.0/WWW/images: All graphical files. z 3.0.0/WWW/lang1: All HTML pages for user defined language 1. z 3.0.0/WWW/lang2: All HTML pages for user defined language 2. z 3.0.0/Sys: Video bitmap font file (Time Stamp and Text Bitmap) z 3.0.0/public: Internal message files.

Note:

When you login the system, the default root directory is 3.0.0/. Do not change any file in 3.0.0/Sys, and

3.0.0/public, because these files are only used internally. to update the content.

For convenience, some FTP utilities (e.g. CuteFTP, WSFTP) may be useful to download the complete pages

3. Upload custom web pages

You can use FTP utilities to upload the updated/added contents to their original directory. For example, if you wish to replace the banner logo (logo.jpg) with your custom made image. First, prepare your own image, and then upload to 3.0.0/WWW/images.

Note: Any file upload to the NDC should be set to “binary” mode in FTP utility; otherwise, the file may be corrupted in the NDC.

After uploading the custom pages, open browser to verify the correctness of contents. If not correct, modify the pages and return to previous step to upload again.

5. Save the changes to flash

Telnet to the NDC. And run command “Up –w” to write the complete web pages into flash. The detailed procedures are list as below, z Open DOS window z Enter “telnet <IP Address of the NDC >” z Enter “root” and “pass” as username and password z Enter “Up –w” to start the web content update program.

The command is case sensitive. Don’t enter the wrong case or you’ll get the command not find error message.

After processing about 30 seconds, the NDC will restart automatically and complete the web content updating.

Now you can open the browser to see the new web content.

Note:

The limitation of overall size of content pages is around 700K Bytes. Any file added/updated plus original downloaded file (~550K Bytes) should not exceed this size; otherwise, some files will be truncated or corrupted. If the corruption of any page happens, you will have to reload the original binary in order to recover the corruption.

For example, the NDC IP address is 192.168.0.200, then

C:\temp>telnet 192.168.0.200

C:\temp>

Telnet session Í Open Telnet session

Login: root
