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.
2

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.

2.4 Network Communication Interfaces
2.4.1 10Base-T RJ-45 Pinout
The 10BASE-T Ethernet network (RJ-45) system is used in the Receiver for network
connectivity. The 10 Mbps twisted-pair Ethernet system operates over two pairs of wires.
One pair is used for receiving data signals and the other pair is used for transmitting
data signals. This means that four pins of the eight-pin connector are used.
Figure 2.5 RJ45 Pinout
2.4.2 10Base-T Crossover Wiring
When connecting the Receiver directly to the computer, the transmit data pins of the
computer should be wired to the receive data pins of the Receiver, and vice versa. The
10Base-T crossover cable with pin connection assignments are shown below.

PART 3
NETWORK CONFIGURATION
3.1 Ethernet (MAC) Address
MAC (Media Access Control) address is your computer's unique hardware number.
When you're connected to the LAN from your computer, a correspondence table relates
your IP address to your computer's physical (MAC) address. The MAC address can be
found on the label of your device and contains 6 bytes (12 characters) of hexadecimal
numbers XX:XX:XX:XX:XX:XX hex
For Example: 0A:0C:3D:0B:0A:0B
Remove the small label with the default IP address and there will be room to put
your IP address. See Figure 2.5.
3.2 Network Protocols
The Receiver can be connected to the network using standard TCP/IP protocols. It also
supports ARP, HTTP (WEB server), DHCP, DNS and Telnet protocols.
3.3 DHCP
DHCP, Dynamic Host Configuration Protocol enables computers and devices to extract
their IP configurations from a server (DHCP server).
If DHCP is enabled on your Receiver, as soon as the Receiver is connected to the
network, there is an exchange of information between DHCP server and the Receiver.
During this process the IP address, the Gateway address, and the Subnet Mask will be
assigned to the Receiver by the DHCP server. Note that the DHCP server must be
configured correctly to do such assignment.
The Receiver is shipped with DHCP disabled (factory default).
If fixed or static IP address is desired, the DHCP must be disabled.
The DHCP can be enabled by setting the DIP switch #3 to the "ON" position
DIP switch #3 shown in "ON" position
Figure 3.1 4 Position DIP Switch on the Bottom Side of Receiver
Setting the Receiver’s IP address to 0.0.0.0 will also enable DHCP.

3.4 DNS
DNS, Domain Name System enables computers and devices to be recognized over a
network based on a specific name instead of IP addresses.
For example, instead of having to use http://192.168.1.200 (IP address), you would use
only http://z03ec or any sixteen character name stored as Host Name under Access
Control menu in the Wireless System Home Page.
The default DNS name for the Receiver is "z" followed by the last four digits of the
MAC address of that particular Receiver.
1. It is very important to communicate with the network administrator in order to
understand DHCP and its existing configurations on the host server,
before enabling DHCP on the Receiver.
2. The Receivers are shipped with a default static IP address of 192.168.1.200
and Subnet Mask of 255.255.255.0.
3. On Windows servers where DCHP and DNS are separate functions it is very
important to configure the DHCP server to communicate with DNS in order
for the iServer’s Host Name to correctly respond. If you cannot access the
iServer using its Host Name, please contact your network administrator to
make sure the DHCP and DNS servers are linked together.
3.5 IP Address
Every active device connected to the TCP/IP network must have a unique IP address.
This IP address is used to establish a connection to the Receiver. Every computer using
TCP/IP should have a unique 32-bit address which is divided into two portions, the
network ID and the host ID. For instance, every computer on the same network uses the
same network ID. At the same time, all of them have a different host ID. For more details
about the IP address see Appendix B.
3.5.1 Default IP Address
The Receiver is shipped with a default IP address of 192.168.1.200 and Subnet Mask of
255.255.255.0. If you are going to use a Web browser or Telnet program to access the
Receiver using its default IP address, make sure that the PC from which you’re
establishing the connection has an IP address that is in the same range as the
Receiver’s IP address (192.168.1.x, where xcan be any number from 1 to 254). See
Section 3.5.2.
Your PC’s IP address cannot be the same as the Receiver’s IP address.
You also need to make sure that your PC’s Subnet Mask is 255.255.255.0. This is a
good way to access the Receiver over the network and make any configuration changes
needed. If 192.168.1.200 is already in use on your network, use an Ethernet crossover
cable between your computer and the Receiver to change the IP address or any other
settings within the Receiver.

PART 4
OPERATIONS
This Receiver can be used and configured in several ways, depending on user’s
preference and network setup. It can be configured using a Web browser, like Internet
Explorer. It can also be configured using the iConnect Configuration Software.
If DHCP and DNS servers are configured to exchange information, the connection will be
very simple. All you need to do is to enable DHCP on the Receiver (see Section 3.3) and
use a straight through network cable to connect the Receiver to an Ethernet hub or switch
and power it up. Now, you can use the Receiver’s default Host (Domain) Name, which is
zxxxx (where xxxx are the last four characters of its MAC address) to access the
Receiver’s Web Server.
If DHCP is not the preferred method, you can configure your PC’s network connection with
an IP address of 192.168.1.x that is in the same range as the Receiver’s default IP
address (192.168.1.200) and connect to the Receiver using a cross-over network cable
between your PC’s network port and the Receiver. After you’re done with configuring the
Receiver, you can always set your PC back to its original settings. See Section 3.5.2 for
more details.
On your computer, from the MS-DOS Prompt window type "ping 192.168.1.200 " and press
Enter. If DHCP and DNS servers are used type " ping zxxxx " , where xxxx are the last four
digits of the Receiver’s MAC address, located on the back of the device. You should get a
reply as shown in Figure 4.1.
4.0 Testing the Connection
Figure 4.1 Pinging the Receiver from MS-DOS Prompt
This proves that the connection is proper and you can get into configuration or run mode
using the Telnet or Web browser.

4.2 Setting a New IP Address over the Network
Besides using the iConnect software, you may use the Receiver’s default IP address to
access it and assign a new IP address to it.
The Receiver is shipped with a default IP address of 192.168.1.200 and Subnet Mask of
255.255.255.0. You can configure your PC’s Network connection with an IP address that
is in the same range as the Receiver’s IP address (192.168.1.x) and connect to the
Receiver using a crossover network cable between your PC and the Receiver.
With this completed, you can go to the DOS-Prompt and ping 192.168.1.200. If you
receive responses back (Figure 4.1), you can go to the Web browser and type in
http://192.168.1.200 and it will take you to the Wireless System’ Home Page.
Select , button, you’ll be asked for the password. You should be on the
Access Control page were you can simply type in the desired Static IP address, and click
Save.
For more details about the " Access Control " page refer to Section 4.3.9.
Figure 4.4 Access Control
For the IP address to take effect, the Receiver needs to be turned OFF and ON using the
"Network Reset" button. Pressing the physical button marked "RESET" on the Receiver
does the same thing.
You can now connect the Receiver to an Ethernet hub using a straight through cable,
power it up, and follow the ping routine mentioned in the previous section.
