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:
3.0.0/WWW: Main video pages including static HTML pages and JAVA applets.
3.0.0/WWW/images: All graphical files.
3.0.0/WWW/lang1: All HTML pages for user defined language 1.
3.0.0/WWW/lang2: All HTML pages for user defined language 2.
3.0.0/Sys: Video bitmap font file (Time Stamp and Text Bitmap)
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.
