Hello,
I copied this page from a device running embeded linux and I want to put it on a different computer on the same network to control this device. My javascript knowledge is bellow zero. The page is looking for local files. I understand that I have to point all the commands to my embeded linux device (url= [url]
Thank you.
This is the page:
<HTML>
<HEAD><TITLE>Matrix3 LX-300 Control Page</TITLE></HEAD>
<BODY>
<H1>Matrix3 LX-300 Control Page</H1>
This is the default web page provided by the LX-ELC EtherTracks module.
