CHAPTER 1 – INTRODUCTION
The X501NET is a network device. It has no local display or keyboard. It is configured through
the same local area network (LAN) connection that it uses to pass the data it collects.
The X501NET has a built-in web server and uses the HTTP protocol for configuration. No
special software is required. Any computer attached to the same LAN as the X501NET can use a
JavaScript enabled web browser (e.g. Internet Explorer, Mozilla, FireFox, etc) to configure the
X501NET.
