1.3 Description (continued)
The Receiver is easy to install, simple to operate, and features award-winning iServer
technology with an Embedded Web Server that requires no special software.
The Receiver serves Active Web Pages to display real time readings and charts of
Temperature and Humidity. You can also log data in standard data formats for use in a
spreadsheet or data acquisition program such as Excel or Visual Basic. iLog is a free and
easy to use program for logging data to Excel.
The virtual chart viewed on the web page is a Java™ Applet that records a chart over the
LAN or Internet in real time. With the Receiver there is no need to invest time and money
learning a proprietary software program to log or chart the data.
Chart scales are fully adjustable on the fly. For example, the chart can display one minute,
one hour, one day, one week, one month or one year. Temperature and humidity can be
charted across the full span (-40 to 125°C, and 0 to 100% RH) or within any narrow range
such as (20 to 30°C).
The OPC Server software makes it easy to integrate the Receiver with many popular Data
Acquisition and Automation programs offered by Omega, Wonderware, iConics, Intellution,
Rockwell Automation, and National Instruments, among others.
The following example illustrates how you can hookup wireless system to your network:
Figure 1.1 Wireless System on the Ethernet Network
The wireless system consists of a single
Receiver
and one or more
Connector /
Transmitters
. Transmitter will send data periodically to the Receiver where it serves as a
gateway between the users and the Transmitter. The users can access the data through
the Receiver’s web server and provided data acquisition software.
A standard web browser can be used to monitor and chart temperature and humidity. The
browser can also be used to configure the device’s IP address, passwords for access and
overall configuration parameters.
