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), datalogging software (iLog), memory card retrieval software/download utility
(iFlash), and Mail Notifier are available at the website listed on the cover page of
this manual or on the CD-ROM enclosed with your shipment.
1.3 Description
Web-based Remote Surveillance of Temperature and Security
The iSE environmental monitor provides Web-based remote surveillance of
environmental conditions in critical HVAC applications such as computer server rooms,
clean rooms, laboratories, museums, warehouses, or any remote facility. View and
record Temperature on two independent thermocouple channels, over an Ethernet
network or the Internet with no special software—just a Web browser.
EMAIL ALARMS -- The device can trigger an alarm if temperature goes 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 cell phones and PDA’s.
PHYSICAL THREATS -- The iSE includes screw terminals for two contact closures that
work with common alarm sensors. You can instruct the iSE monitor to send an alarm if a
door is opened, a window is broken, or a fire sprinkler goes off.
POWER FAILURE -- The iSE monitor can trigger an alarm if the AC power fails. The
iSE monitor will continue to collect data for ten days powered by a standard 9 Volt
alkaline battery (included). The data is stored in nonvolatile flash memory and can later
be downloaded over the Ethernet.
2
LOCAL ALARMS -- The iSE includes two 1.5 Amp output relays that are controlled by
the alarm conditions you select. The relays can trigger flashing lights and a siren for
example to alert personnel near the scene.
With the easy Web-based setup page, the two relays can be programmed for two
temperature inputs, and high or low set points, as well as alarm conditions triggered by
contact closures. The relays can also be programmed to turn off when conditions return
to normal, or programmed to remain latched and require a manual reset.
VIEW CHARTS AND GRAPHS ON THE WEB -- The iSE serves Active Web Pages to
display real time readings, display charts of temperature, or log data in standard data
formats for use in a spreadsheet or data acquisition program such as Excel or Visual
Basic.
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 iSE, 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 can be
charted across the full span or within any narrow range.
You can chart temperature from one thermocouple, two thermocouples, and/or the
differential between the two. The iSE can take thermocouple types J, K, T, E, R, S, B, C,
N and L measuring temperatures up to 1,820°C (3,308°F). The iSE can display and chart
absolute measurements in two locations and a differential measurement between the two
locations. The iSE comes with a pair of type K thermocouples.
LINK TO WEB CAM OR IP CAMERA -- The Web page includes a link to a “Web Cam”
or “IP camera” (not included). If you get a message about an alarm condition, you can
quickly click on the link to view the actual scene over the Internet.
FLASH MEMORY -- The iSE records data on a removable 2-MByte Flash Memory card
(included) that can store one full year of readings taken at one-minute intervals (or two
months of readings taken at ten second intervals).
Up to four years of temperature readings can be stored on the optional 8 MByte card.
Even if the Ethernet network fails, data will continuously record on the built-in nonvolatile
flash memory.
Installation and operation of the iSE monitor requires no special training, tools, or
software. The device connects to any Ethernet network with standard cable and is
powered by a universal AC adapter which is supplied with the product.
AWARD-WINNING TECHNOLOGY -- The iSE is simple to install and use, and features
award-winning iServer technology that requires no special software except a Web
Browser.
The iSE 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 "Server Room" in any Web Browser, and the iSE serves a Web Page
with the current readings.
3
TYPICAL APPLICATIONS -- The iSE is great for monitoring and recording temperature
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.
The following example illustrates how you can hookup an iSE, a network display (iLD),
and a network camera to your network:

NETWORK CONFIGURATION
3.1 Network Protocols
The iSE 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 a label attached to 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
Figure 3.1 Labeling

OFF
ON
DHCP, Dynamic Host Configuration Protocol enables individual computers or devices to
extract their IP configurations from a server (DHCP server). If the DHCP is enabled on
your iSE, as soon as the iSE is connected to the network, there is an exchange of
information between DHCP server and the iSE. During this process the IP address, the
Gateway address, and the Subnet Mask will be assigned to the iSE by the DHCP server.
Note that the DHCP server must be configured correctly to do such assignment.
If fixed or static IP address is desired, the DHCP must be disabled. The iSE is shipped
with DHCP disabled (factory default). The DHCP can be enabled by setting the DIP switch
#3 to the “ON” position (refer to Figure 3.2).
DIP switch #3
To enable the DHCP,
besides using DIP switch
shown in
“ON” position
#3, set the iSE’s IP
address to 0.0.0.0.
An iSE with IP address of
0.0.0.0 will request an IP
address, gateway
address, and subnet
mask from the DHCP
server over the Ethernet.
3.4 DNS
Figure 3.2 DIP Switch on the Bottom Side of iSE
DNS, Domain Name System enables individual computers and devices to be recognized
over a network based on a specific name instead of an IP address. For example, instead
of having to use http://192.168.1.200 (IP address), you would use only http://eis03ec or
any eight character name stored as Host Name under the Access Control page in the iSE
Home Page. The default DNS name for an iSE is "eis" followed by the last four digits of
the MAC address of that particular iSE.
1. It is very important to communicate with the network administrator in order to
understand the DHCP and its existing configurations on the host server,
before enabling the DHCP on the iSE.
2. The iSE’s 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 DHCP and DNS are separate functions it is very
important to configure the DHCP server to communicate with the DNS in order
for the iSE’s Host Name to correctly respond. If you cannot access the iSE
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 build a connection to the iSE. Every computer using TCP/IP
should have a unique 32-bit address. It 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.

Telnet 192.168.1.200
The iSE is shipped with a default IP address set to 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
iSE 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 iSE’s IP address
(192.168.1.x, where x can be any number from 1 to 254.
Your PC’s IP address cannot
be the same as the iSE’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 iSE 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 iSE to change the IP address or any other settings
within the iSE.
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 an interface between an application running on your
computer and the network through the TCP/IP protocol.
There are three default TCP socket port numbers assigned to the iSE:
1. Port (socket) number 1000 when using HTTPget program.
2. Port (socket) number 2000 when trying to access the sensor (probe) connected to
the port of the iSE to receive data.
3. Port (socket) number 2002 when trying to access the iSE itself for Power
Recycling the iSE remotely. This can be done using Windows standard Telnet
application.
Power recycling the iSE can also be done through the iSE’s Web Server (see Section 4.2).
Telnet stands for Telecommunications Network, is a protocol that provides a way for
users (or clients) to connect to computers (or servers) on a network, whether in the next
building or across the world.
Example: C:\>Telnet 192.168.1.200 2002
You will then get the following screen.
You can open a Telnet session using other terminal emulation programs like Tera Term
Pro (downloadable from the internet), which is a free software for MS-Windows. It
supports VT100 emulation, Telnet connection and serial com port connections.

OPERATIONS
This iSE 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 the 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 iSE (see
Section 2.2) and use a straight network cable to connect the iSE 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 iSE’s default IP address
(192.168.1.200) and connect to the iSE using a cross-over network cable between your
PC’s network port and the iSE. After you’re done with configuring the iSE, 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 iSE’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 iSE 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.
4.0 Testing the Connection
This proves that the connection is proper and you can get into configuration or run mode
using the Telnet or Web browser.
