INTRODUCTION

1.1 Safety and EMC Considerations

Refer to the Environment/Operating Conditions Section

EMC Considerations

•Whenever EMC is an issue, always use shielded cables.

•Never run signal and power wires in the same conduit.

•Use twisted-pair wires for signal connections.

•Install Ferrite Bead(s) on signal wires close to the instrument if EMC problems persist.

Failure to follow all instructions and warnings may result in injury!

1.2 Before You Begin

Inspecting Your Shipment: Remove the packing slip and verify that you have received

everything listed. Inspect the container and equipment for signs of damage as soon as

you receive the shipment. Note any evidence of rough handling in transit. Immediately

report any damage to the shipping agent. The carrier will not honor damage claims

unless all shipping material is saved for inspection. After examining and removing the

contents, save the packing material and carton in the event reshipment is necessary.

Customer Service: If you need assistance, please contact the Customer Service

Department nearest you.

Manuals, Software: The latest Operation Manual as well as free configuration software

(iConnect), data-logging software (iLog) and Mail Notifier are available at the website

listed on the cover pages of this manual, or on the CD-ROM enclosed with your shipment.

1.3 Description

The UWTC-REC3 Wireless Receiver provides Web-based monitoring of Temperature and

Humidity. Each Receiver can directly support up to thirty-two (32) Thermocouples, RTD,

Infrared and Humidity wireless Connectors / Transmitters.

The Receiver allows you to monitor and record Temperature and Relative Humidity over an

Ethernet network or the Internet without any special software-just your Web Browser. The

Receiver includes AC adapters to operate on any voltage worldwide from 100 to 240 Vac

and 50 to 60Hz. The Receiver connects directly to an Ethernet Network or the Internet.

Unlike an RS232 or USB device, it does not require a host computer.

The Receiver also provides error detection mechanism for inactive communication and

diagnostic information including signal strength and data transmission success rate to

help trouble shooting potential wireless system installation issues.

The Receiver is an independent node on the network sending and receiving data in

standard TCP/IP packets. It is easily configured from a Web Browser and can be password

protected. From within an Ethernet LAN or over the Internet, the user simply types the IP

address (such as 192.168.1.200) or an easy to remember name (such as "ServRoom" or

"Chicago5") and the Receiver serves a Web Page with the current readings.

The device can trigger an alarm if variables go above or below a set point that you

determine. Your alarm can be sent by email to a single user or to a group distribution list,

including text messages to Internet enabled cell phones and PDA’s. The "Mail Notifier"

software is free and easy to use program for this application.

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.
