1.3 Description
View Temperature + Humidity with a Web Browser. The iServer let’s you monitor and
record Temperature, Relative Humidity and Dew Point over an Ethernet network or the
Internet with no special software except a Web browser. The iServer serves Active Web
Pages to display real time readings, display charts of temperature and humidity, or log
data in standard data formats for use in a spreadsheet or data acquisition program such
as Excel or Visual Basic.
Adjustable Charts. The Java™ Applet 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. Users can select channel 1, channel 2 or the difference of the two channels.
Temperature and humidity can be charted across the full span (-40 to 124ºC, and
0 to 100% RH) or within any narrow range (such as 20 to 30ºC).
Display and Chart Two Channels. The iServer transmitters come complete with a
humidity + temperature probe for measurement of a single location. With the addition of a
second probe, the transmitter can measure and display humidity + temperature and
dewpoint in a second location up to twenty feet away. The transmitter can display and chart
absolute measurement in both locations, or a differential measurement between the two
locations. The second probe requires no change to the basic iServer transmitter hardware,
firmware or software. A second probe can be added at the time of purchase or in the
future. There is a choice of industrial probes in 2 inch and 5 inch (51mm and 137mm)
lengths, and a wand style for ambient indoor applications. A simple DB9 “Y” connector is
available for adding a second probe to the iTHX-W. No connector is required to add a
second probe to the DIN rail mounted iTHX-2

winning technology that requires no special software except a Web Browser.
The iServer connects to an Ethernet Network with a standard RJ45 connector and sends
data in standard TCP/IP packets. It is easily configured with a simple menu using a Web
Browser and can be password protected. From within an Ethernet LAN or over the
Internet, the user simply types its IP address or an easy to remember name such as
"Cleanroom 5" or "Midwest Server Room" in any Web Browser, and the iServer serves a
Web Page with the current readings.
Typical Applications: The iServer is great for monitoring temperature + humidity in
applications such as: clean rooms, computer rooms, HVAC systems, pharmaceutical
and food processing and storage, hospitals, laboratories, semiconductor fabs, electronic
assembly, warehousing, museums, manufacturing, greenhouses, farm animal shelters,
and many more.
Email Alarms: All iServer models that are on a LAN that is connected to the Internet can
trigger an alarm that can be sent by email to a single user or to a group distribution list,
including text messages to cell phones and PDA’s.
This device can be purchased as a stand alone DIN Rail mounted unit (iTHX-2) or,
as a bench/wall mount unit (iTHX-W), or as a bench/wall mount unit with an LCD
display, Flash Memory Card and Back-up Battery (iTHX-SD).
The following example illustrates how you can hookup an iServer to your network:
A standard web browser can be used to monitor and chart temperature, humidity, and
dew point. The browser can also be used to configure the device’s IP address,
passwords for access and overall configuration parameters. An iLD Big Display can
display temperature, humidity and dewpoint received from an iServer over the Ethernet
or the Internet.
The following example illustrates how you can hookup an iServer and iLD to your
network:

3.1 Network Protocols
The iServer can be connected to the network using standard TCP/IP protocols.
It also supports ARP, HTTP (WEB server), DHCP, DNS and Telnet protocols.
3.2 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 3.1

DHCP, Dynamic Host Configuration Protocol, enables computers and network devices to
receive their IP configurations from a DHCP server.
If DHCP is enabled on your iServer, as soon as the iServer that is connected to the
network is powered on, there will be an exchange of information between the iServer and
the DHCP server. As a result, the DHCP server will assign an IP address, a Gateway
address, a Subnet Mask, and a DNS address to the iServer. Note that the DHCP server
must be correctly configured to make such assignments.
If fixed or static IP address is desired, the DHCP function must be disabled.
The iServer is shipped with DHCP disabled (factory default).
The DHCP can be enabled by setting the DIP switch #3 to ON position (refer to Figure
3.2).
It’s 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 iServer.
The iServer is shipped with a default static IP address of 192.168.1.200 and
Subnet Mask of 255.255.255.0.
DIP switch # 3 shown in “ON” position
Figure 3.2 DIP Switch on iServer
Setting the iServer’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
http://eis03ec or any name up to sixteen alphanumeric characters defined as a Host
Name in the iServer’s web server.
The default Host Name for an iServer is "eis" followed by the last four digits of the MAC
address of that iServer unit.
On Windows servers where DHCP 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
DHCP and DNS servers are linked together.
101011
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 build a connection to the iServer.
All network devices like computers that use TCP/IP protocol to communicate with each
other should have a unique 32-bit address called IP address. The IP address 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 different
host IDs. For more details about the IP address see Appendix B.
3.5.1 Default IP Address
The iServer 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
iServer 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 iServer’s
IP address (192.168.1.x, where x can be any number from 1 to 254.
Your PC’s IP address cannot
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 iServer 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 iServer to change the IP address or any other
settings within the iServer.
3.6 Port Number
All TCP connections are defined by the IP address and a port number. A port number is
an internal address that provides a TCP/IP interface between an application software on
a computer and a device on the network or between two devices on the network.
There are three default TCP socket port numbers assigned to the iServer:
1. Port 1000 when using HTTPget program (see Section 4.5).
2. Port 2000 when trying to access the sensor (probe) connected to the port of the
iServer to receive data.
3. Port 2002 when trying to access the iServer itself for Power Recycling the iServer
remotely. This can be done using Windows standard Telnet application.
Power recycling the iServer can also be done through the iServer’s Web Server (see
Section 4.2).
Telnet stands for Telecommunications Network, it is a protocol that provides a way for
users to connect to computers (or servers) on a network, whether in the next building or
across the world.

This iServer 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 Netscape
or Internet Explorer. It can also be configured using iConnect Configuration Software.
If DHCP and DNS servers are used, the connection is very simple, no need to find the
right IP address or watch for network conflicts, these are all done for you by your network
DHCP and DNS server. All that is left for you to do, is to enable DHCP on the iServer (see
Section 2.2) and use a straight network cable to connect the iServer to a hub and power
it up.
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 iServer’s default IP address
(192.168.1.200) and connect to the iServer using a cross-over network cable between your
PC’s network port and the iServer. After you’re done with configuring the iServer, you can
always set your PC back to its original settings.
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 eisxxxx”, where xxxx are the
last four digits of the iServer’s MAC address, located on the back of the device. You should
get a reply as shown in Figure 4.1.
You can use the iServer’s host name (eisxxxx) instead of its IP address only if
your DHCP server is configured to communicate with your DNS. Please consult
with your IT department for details.
