INTRODUCTION

1.1 Safety and EMC Considerations

Refer to the CE Approvals Section.

EMC Considerations

W Whenever EMC is an issue, always use shielded cables.
W Never run signal and power wires in the same conduit.
W Use twisted-pair wires for signal connections.
W 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) and datalogging software (iLog) 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
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 -- just a Web browser. The iServer serves Active Web
Pages to display real time readings and display charts of temperature, humidity and dew
point, 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 day, one week, one month or one year. 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).

When a second sensor is added, users can select a chart that records channel 1,
channel 2 or the difference of the two channels.

SD Flash Memory Card. The iServer comes complete with a removable 2 GB SD Flash
Memory card that can store up to seven years of readings taken at ten second intervals.
The data is recorded on widely available SD (Secure Digital) flash cards. The format is a
simple text file that is easily imported to spreadsheets and other programs. It can be read
on a PC or MAC with a USB card reader. You can also download the data remotely over
an Ethernet network or the Internet.

Installation and operation of the iServer requires no special training, tools, or software.
The device connects to any Ethernet network with standard cable and is powered by a
universal 100 to 240 Vac adapter which is supplied with the product.

2

1.3 Description (continued)
Back-up Battery. The iServer comes with a universal 100 to 240 Vac power adapter.

A standard 9 Volt Alkaline battery (also included) allows the device to continue recording
data for 60 hours (at one minute interval setting) without external ac power (such as a
power outage).

Display and Chart Two Channels. The transmitter comes complete with a temperature
and humidity probe for measurement of a single location.

With the addition of a second probe, the transmitter can measure and display
temperature, humidity and dew point in a second location up to ten feet away.

The transmitter can display and chart absolute measurements in both locations, or a
differential measurement between the two locations. The second probe requires no
change to the basic transmitter hardware, it can be added at the time of purchase or in
the future. A choice of industrial probes in 2” and 5” lengths, and a wand style for ambient
indoor applications are available. A simple DB-9 “Y” connector is required for adding a
second probe.

Sensor and Calibration. It is not necessary to take the iTHX-SD out of service for
routine calibration. The temperature/humidity sensors are interchangeable and can be
replaced for about the same cost as a typical calibration. Replacement sensors with
optional 3-point NIST traceable calibration certificates are available.

Email Alarms. The device can trigger an alarm if temperature or humidity 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.

Alarm Relays. The iServer features two 1.5 Amp relays. With the easy Web-based setup
page, the two relays can be programmed for any combination of temperature or humidity,
and high or low set points. The relays can also be programmed to remain latched and
require a manual reset if a limit is exceeded.

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.

1.3 Description (continued)

SMTP SNMP Server

Award-winning Technology. The iServer is simple to install and use. It features
award 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
“Cleanroom5” or “ServerRoom” in any Web Browser, and the iServer serves a Web Page
with the current readings. The iServer comes complete with one temperature/humidity
wand probe, universal ac power adapter, 9V battery, SD card, and full documentation.

Example:

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 all configuration parameters. An iLD Big Display can display temperature
and humidity 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:

2.5.1 10/100 BASE-T RJ-45 Pinout

The 10/100BASE-T Ethernet network
system is used in the iServer for
network connectivity. The 10 Mbps
or 100 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

For CE compliance at 100
Mbps: use shielded cable,
opposite end of cable must be grounded.

2.5.2 Connecting iServer to PC/Hub/Switch/Router

The iServer’s Ethernet interface can automatically detect the Rx and Tx lines on a
twisted pair Ethernet cable (MDI/MDIX Auto Cross). Therefore, to connect an iServer to a
PC/Hub/Switch/Router, either a straight-through or a cross-over cable can be used.

On certain devices (like iServer), it is possible for the hardware to automatically
correct errors in cable selection, making the distinction between a “straight­through” cable and a “cross-over” cable unimportant. This capability is known as
“Auto MDI/MDIX”.

2.6 Relay Wiring Connections

To access the Relay Connector you must remove the cover, refer to Section 2.4.
It is recommended that you ground your unit by connecting a wire to the

Ground/Return position of the relay connector.

PART 3
NETWORK CONFIGURATION

3.1 Network Protocols

The iServer can be connected to an Ethernet network communicating through standard
IP protocols including TCP, UDP, SNMP, SMTP, ARP, HTTP (WEB access), DNS,
DHCP, ICMP, SNTP, and Telnet.

3.2 Ethernet (MAC) Address

MAC (Media Access Control) address is a unique hardware number for Ethernet devices
like computers, network switches, print servers, etc. When you’re connected to an
Ethernet LAN using a computer you can see a table of IP addresses called “ARP table”
stored on that computer. The ARP table relates IP addresses of devices on a network
to their corresponding MAC addresses. The MAC address can be found on a label
attached to your Ethernet device and it 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 of 192.168.1.200 and there
will be room to put your IP address. See Figure 3.1

FIRMWARE VERSION #

3.3 DHCP

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 accessing the iServer’s web server and selecting Network

menu (refer to Section 4.4.2) or by pressing and holding the two front buttons °C/°F and
TIME/IP during power-on (refer to Section 2.3).

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.

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://ithx03ec 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 “ithx” 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.

If DNS server address is setup, all Host Names reported during weblink configuration
(i.e. SMTP server IP, SNTP server IP, SNMP trap server IP, etc.) will be translated into
IP addresses.

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.

11

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 two default TCP port (socket) numbers assigned to the iServer:

1) Port 2000: Once a TCP connection is made to the iServer using port 2000 or any
port number that is configured on the iServer for Local Port (see Network menu,
Section 4.4.2), the iServer can then be polled for variables like temperature,
humidity, etc. using commands. For the list of commands see Section 4.9.1.

2) Port 2002: This port is the iServer’s network console port for reading or changing
the settings within the iServer. For the list of settings refer to Section 4.8.1. For both
of the above cases, for example, a Telnet application can be used.

PART 4
OPERATIONS

Depending on user’s preference and network setup, the iServer can be configured in
several ways:

Using the latest versions of Web browsers like Internet Explorer, Firefox, Opera, or
Safari (iPhone) the iServer’s Web server can be accessed, see Section 4.2.

It can also be configured using a TCP connection to port 2002 using a command line
interface, see Section 4.8.1.

The iCONNECT Configuration Software can also be used to find and configure the
iServer over the Ethernet, see Section 4.1.2.

Before you configure the iServer, you will need to assign an IP address to the
unit. Refer to Section 4.1.1, 4.1.2 or 4.1.3.

4.1 IP Address Assignment

4.1.1 DHCP (Method 1)

The DHCP server will assign an IP address, see Section 3.3.

4.1.2 ARP HTTPget Commands (Method 2)

You can download the HTTPget program from our web site to use it for this section.

1. From the Command line (DOS prompt) where you keep the HTTPget.exe file, type the

following:

arp -s 128.100.101.76 00-03-34-00-9c-5c press the <Enter> key

128.100.101.76, for example, is the IP address that you want to assign to your iServer

and 00-03-34-00-9c-5c is the MAC address of your iServer labeled on the bottom of the
unit.

2. From the same prompt, type the following HTTPget command:

httpget -r -S “00000000” 128.100.101.76:1 press the <Enter> key

00000000 is the default ADMINISTRATOR password in your iServer unit and

128.100.101.76:1 is the IP address that your iServer will accept on TCP port 1. At this

point, you have successfully assigned 128.100.101.76 IP address to your iServer.

4.1.3 Direct Connection (Method 3)

The iServer is shipped with a default IP address of 192.168.1.200 and Subnet Mask of

255.255.255.0.

To start, connect your iServer directly to your PC using a straight or cross-over Ethernet
cable and power it on.

Make sure that the Network LINK/ACT LED on the iServer and your Ethernet switch is
solid ON. Refer to Figure 4.2.

If you are going to use a Web browser or Telnet program to access the iServer using
its default IP address of 192.168.1.200, you need to 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.

For example, you can assign your PC an IP address of 192.168.1.x, where x is any
number from 1 to 254.

Your PC’s IP address cannot be the same as the iServer’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 iServer over the network and make any configuration

changes needed.
Changing your PC’s IP address is temporary and it’s only for the purpose of accessing

the iServer for initial configurations like assigning a new IP address, subnet mask, etc.
Once the iServer is configured you can put your PC back to its original IP settings.
If 192.168.1.200 is already in use on your network, connect the iServer directly to

your computer using a CAT5 Ethernet cable (either straight or cross-over cable will be
detected by the iServer) and proceed as described below.

Figure 4.13 Network: IP Configuration

DHCP – If the box is checked the iServer will dynamically request an IP address, a

subnet mask, a gateway address, and a DNS address from the DHCP server. By default
the DHCP option is disabled. For more information about DHCP, see Section 3.3.

DHCP can be enabled by pressing and holding the two front buttons ºC/ºF and

TIME/IP during power-on (refer to Section 2.3).

MAC Address – This Indicates the hardware address of the iServer and it is non-
configurable. For more information about MAC Address, see Section 3.2.

IP Address – This indicates the IP address of the iServer. The iServer’s default IP

address is 192.168.1.200. When DHCP is enabled this field will be dimmed. Consult with
your IT department for obtaining an IP address.

Subnet Mask – It’s a 32-bit number that is used to determine which part of the IP
address is the network portion and which part is the host portion. When DHCP is enabled
this field will be dimmed. The iServer’s default Subnet Mask is 255.255.255.0. Consult
with your IT department for obtaining a subnet mask.

21

4.4.2.1 IP Configuration (continued)

Gateway Address – This points to the router that forwards traffic to a destination

address outside of the subnet on which the iServer resides. This is the IP address of the
router which functions as a gateway. When DHCP is enabled this field will be dimmed.
The iServer’s default Gateway address is 0.0.0.0. Consult with your IT department for
obtaining a gateway address.

DNS Address – In order to use the hostname to access the iServer, the DNS server on
your network must be configured, refer to Section 3.4. iServer plays the role of a DNS
client, in the sense that the iServer will actively query the DNS server for the IP address
associated with a particular domain name. When DHCP is enabled this field will be
dimmed. The iServer’s default DNS address is 0.0.0.0. Consult with your IT department
for obtaining a DNS address.

Host Name – If DHCP is enabled, the iServer will send this name to the DHCP server.
This name is used so that the iServer can be accessed based on a specific name instead
of an IP address. For example, instead of using http://192.168.1.200 (IP
address), you would use http://ithxA838 or any name up to sixteen (16) alphanumeric
characters. The default Host Name for an iServer is “ithx” followed by the last four digits
of the MAC address of that particular iServer.

On Windows servers where DHCP and DNS are separate functions it’s 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.

Protocol – It’s the network protocol the iServer communicates with the Ethernet
Network. Options are TCP and UDP. The default is TCP.

Local Port – The default port is 2000. Refer to Section 3.6.
Web Server Port – The default port is 80. This is the primary port number for the HTTP

protocol used for communication between internet browsers and web sites/web servers.
Web servers open this port then listen for incoming connections from web browsers.
Similarly, when a web browser is given an IP address (like the iServer’s IP address),
it assumes that the iServer’s web server is listening for connections on port 80. If this
port is changed to anything but 80 then on the browser the new port number must be
indicated with a colon (
changed to 500, you will then need to type http://192.168.1.200:500 on the browser to
access the iServer’s web server.

One of the applications where the Web Server Port number may need to change
is when users want to access the iServer’s web server from outside the local
area network (i.e. Internet). By setting up “Port Forwarding” inside a router that
is the gateway to that local area network this task can be accomplished. “Port
Forwarding” technique uses the Web Server Port number to forward the Internet
connection to the iServer on the LAN.

Web Link Title – This is a text field that appears on the button on the iServer’s Web Link
Page, refer to Section 4.7. This can describe the Web Link Address assigned below.

Web Link Address – This provides a link to any TCP/IP node on the network or any
Web link on the Internet. Examples would be www.123abc.com or if you have a device
with an embedded Web server (just like the iServer) once you enter its IP address in this
field and click on the Web Link button on the iServer’s Welcome page you’ll be able to
access your device using the same browser interface.

Auto-Negotiation – It is the link, in terms of speed and duplex, between the iServer and

another Ethernet device like an Ethernet switch.
If Auto-Negotiation box is checked, the iServer will auto-negotiate the speed and duplex

with the attached Ethernet device. If any of the other options are selected, the speed
and duplex will be fixed.

It’s important to have the same Ethernet port configuration on the iServer and the
attached Ethernet device. If iServer cannot auto-negotiate with the attached Ethernet
node it will default to 10 Mbps and Half-Duplex. Once Auto-Negotiation is checked, other
fields under this category will be dimmed. By default the Auto-Negotiation is checked.

If the iServer detects the link to be 100 Mbps the 100 BASE-T LED will be solid
green.

Server Type – Options are Command and Continuous.

If Command is selected the iServer will respond to commands sent from a network host
(for the list of commands refer to Section 4.9.1).
If Continuous is selected the iServer will send temperature, humidity, dewpoint values
and alarm relay status once every time amount selected in the Interval box.
The Command and Continuous modes operate when a network host opens a TCP
connection to the iServer’s IP address with port 2000.
In UDP Command mode, iServer will respond back with a UDP packet (to the _ address
and port) if a host application sends a UDP command to iServer’s IP address with port

2000.

In UDP Continuous mode, iServer starts sending continuous data if a host application
sends a trigger or UDP packet to iServer’s IP address with port 2000.
Interval – This is the time interval (in seconds) between each data transmission when
the iServer is in Continuous mode. The default value is set to 5 seconds and the
minimum is 2 seconds.
Time Stamp – If checked, the iServer will stamp the data with date and time before
sending it out to a network host. This will apply to Command and Continuous modes.
Default is unchecked.
Disconnect After Data Sent – If checked, once the iServer responds back with data, the
iServer will close the TCP connection that had been made from the network host.
This feature should be used if data acquisition software expects data to be ended by
closing TCP connection from the client.

4.4.4 Management

This page provides the iServer’s email, SNMP and alarm settings. SNMP (Simple
Network Management Protocol) is the protocol used by network management systems to
communicate with network devices that respond to SNMP connections for the purpose of
problem detections and corrections.
If SNMP and/or SMTP features are desired, please make sure iServer’s network setting
as well as SNMP trap server and SMTP mail server are setup properly. Failure to do so
may cause iServer to be unresponsive while waiting for these servers to reply back.
Fields are described below.

“control station”, which is the place where the iServer is located. This field takes up to 16
alphanumeric characters.

29

4.4.4.1 Setup (continued)
SNMP Trap Server – This field contains the IP address of the SNMP trap server located

somewhere on the network. The trap server listens for SNMP traps coming from the
iServer when there is an alarm condition (refer to Alarms Section 4.4.4.2 under the
Management page).

Simple Mail Transfer Protocol
SMTP Server – This field specifies the IP Address of the SMTP server.

1) You must have an email server (SMTP server) on your network in order to
receive emails generated by the iServer.

2) iServer does not support SMTP server authentication.

SMTP Server Port – This specifies the TCP port used by the SMTP Server. The default is 25.
From – This field specifies the name of the person who sends the email. It can also be

an email address.
To – This field specifies the email address of the recipient. This field can take up to 200

alphanumeric characters; limited to 4 addresses of 50 characters each. Each address
should be separated by a comma, without spaces. Ex: [e-mail],[e-mail]

You can create a “distribution group address” if you need to have more email
addresses.

Subject – This field specifies the subject of the email. Emails for all the alarms will have
this common subject line. Example of a subject can be “Alarm from iServer”.

Reminder Interval – This field sets a reminder interval for email and/or trap to be sent
again. The allowed minimum value is 1 minute. If it’s set to 0 the iServer will not send a
reminder email. The default is 60 minutes.

Power Reset alarm is only sent once, regardless of reminder interval.
Transmission Delay – Once the iServer alarm condition is met, this is the amount of

time the alarm condition is met before iServer sends any email or trap. If it’s set to 0,
email and/or trap will be sent immediately. The default is 1 minute.

4.4.4.1.1 Sending Text Messages to a Cell Phone

In the SMTP To field, you can use the following format to have the iTHX-SD send a text
message to your cell phone. Since most cell phones are capable of receiving text messages
you just need to find the correct email format for your cell phone provider.

T-Mobile [e-mail]
Virgin Mobile [e-mail]
AT&T [e-mail]
Sprint [e-mail]
Verizon [e-mail]
Nextel [e-mail]
“phone_number” is your 10 digit cell phone number.

4.4.4.2 Alarms

This includes events or conditions. Once a condition is met the iServer will send an email
or/and an SNMP trap if either one or both are checked. Fields are described below.

Multiple alarm events can be checked and for each event an email and/or a trap
will be sent.

4.4.6.1 Start Recording (continued)

Category – The options are Continuous and Scheduled.

In Continuous recording Start Date and Start Time fields are required. If there is not an
End Date and End Time, the recording will continue non-stop.

In Scheduled recording, any of the days can be selected and the recording will take
place only on those days. Here are some important notes about the Scheduled
recording:

W The Start Date, Start Time, and Stop Time must be defined. The Stop Date does not

apply to Scheduled recording. This means that the Scheduled recording will never
stop until the user decides to stop it.

W If the Start Date is one of the selected days recording will start on that day.
W If the Start Date is not one of the selected days recording will start on the next 1st

selected day.

W The Start Time and the Stop Time apply to every single day that is selected.
W The Start Time is the time that recording will start on those selected days.
W The Stop Time is the time that recording will stop on those selected days.
W The Start Time must be earlier (at least 20 seconds) than the stop time.
W Let’s say today we’re configuring the unit for Scheduled recording. If the Start Time

is earlier than the Current Time (real time clock) and today is one of the selected
days, the recording will start immediately.

W Scheduled recording is suitable for users who want to start and stop recording at

certain times on certain days. Users who want to have continuous recording three
days a week, for instance, this feature can also be used. Just make sure to select
start and stop times that would link the three days together.

For example, we need to have 3 days (72 hrs) a week continuous recording
(Monday, Tuesday, and Wednesday) with recording Interval of 1 minute. The Start
Time should be 00:00:00 and the Stop Time should be 23:59:00. This will connect
all 3 days together and it will run on weekly bases.

Start Date – This is the date on which the data recording must start.
Start Time – This is the time that the recording will start. It’s based on a 24-hour format.

The Start Time must be at least twenty seconds after the Current Time (real time).
Stop Date – This is the date on which the data recording will stop. Stop Date does not

apply to Scheduled recording.
Stop Time – This is the time that the recording will stop. It’s based on a 24-hour format.

A failure on the Ethernet network will not interrupt data recording.

Upgrade

Consult manual for complete instructions.

Figure 4.28 System: Upgrade

Upgrade – This option loads a new firmware into the iServer over the network. The

firmware is a binary file with .bin extension. This file must be kept on the same PC from
which the iServer is accessed.

If you have an iServer with a firmware version previous to 1.09.0, it is mandatory to set

the iServer to default settings after a firmware upgrade to any version, after 1.09.0.

Once the firmware upload is completed the iServer will power reset itself. This typically
takes about 30 seconds.

When doing firmware upgrade on the iServer, there should be NO other
on-going or new Web server (HTTP) connections made to the device; otherwise,
the iServer will not upgrade the firmware. You can do either of the following to
prevent this from happening:

1. Connect the iServer directly to the PC using a straight or crossed Ethernet cable. This

will also help to have a faster firmware upload.

2. From the “Network” menu, change the Web Server Port, for example, to 500 (default

is 80), save the change, and reset the power on your iServer. The next time you will
access the iServer’s Web server, you must type http://192.168.1.200:500 where

192.168.1.200 is the IP address of the iServer and 500 is the new Web server port
(HTTP port).

39

4.4.7.3 Upgrade (continued)

Either one of the above options will make you the only user on that iServer.
Set the iServer to default settings after the firmware is upgraded.
See Section 4.4.7.2 on how to set the iServer to default settings.
Applying default settings will change the iServer’s settings to factory defaults.
If those settings are important to you and you do not want to reconfigure the iServer, you

will need to do the following steps.
From the “System” menu:

1) “Download” the iServer’s configuration settings, Section 4.4.7.4.

2) “Upgrade” the iServer with the new firmware, Section 4.4.7.3.

3) Set the iServer to “Default” settings. The iServer’s IP address is now

192.168.1.200.

4) “Upload” the same configuration you obtained from step 1 onto the iServer,
Section 4.4.7.5.

After you have successfully upgraded your device, you can verify the firmware
version number on the “Overview” page (see Section 4.4.1).

4.4.7.4 Download Configuration

Clicking on this button will download the configuration file that contains all the settings
stored in the iServer and use it as a reference.

4.8 Telnet Setup

With a telnet program, you can connect to the iServer using its IP address and TCP Port

2000. In Continuous mode (refer to Configuration:Sensors page Section 4.4.3.2), the
telnet session will receive continuous data (temperature and humidity) from the iServer.
In Command mode, a command can be sent to query the iServer.

Refer to Section 4.9.1 for list of commands.

4.8.1 Telnet Connection

Telnet stands for Telecommunications Network, it is a protocol that provides a way for
users to connect to a node with a valid IP address anywhere on an Ethernet network or
the Internet . You can open a Telnet session using a terminal emulation programs like
Tera Term (downloadable from the internet), which is a free software for Windows.

You can initiate a telnet connection by typing the IP address of the iServer, and Port
2002 for logging into the iServer’s telnet consol port (see Figure 4.36). By telneting to
Port 2000, you will be able to access temperature, humidity, and dew point readings.

The default password for Telnet Login is 00000000 and can be changed if

desired.

Once the connection is established you will be prompted for an Administrator Password
(default is 00000000). Telnet console port (2002) allows users to configure some
parameters within the iServer. Figure 4.38 shows the parameters that can be changed.

After connecting to the iServer, you can use the following commands to read, modify,
and get help.

p displays the current settings (Figure 4.37)
? displays all the available options as well as an example on how to enter a

command (Figure 4.38)
s set a new configuration (see the example in Figure 4.38), sending the

command c is required to permanently store the new settings
RESET restart the iServer
FACTORY set the iServer to it’s factory default, the RESET command is required after

the FACTORY command

c permanently store the new settings
q quit the telnet session

4.9 HTTPget Program

The HTTPget software is used to send a single HTTP or TCP request to an iServer
product. In contrast, the telnet or Hyperterminal programs allow a continuous
connection with multiple requests to be sent to the iServer product.

Generally HTTPget is used for simply programming an IP address to the iServer or for
quickly obtaining a reading of from a device.

The iServer product must be configured from the configuration web page so that the
“Server Type” value is set to “Command”, refer to Section 4.4.3.2.

47

4.9.1 HTTPget using Port 2000

You can setup and read the information from the iServer by using the HTTPget program.
The following program can be used to read data from the iServer by using TCP port

2000. The command string is sent to this TCP port, then the response can be read back
from the same socket.

The HTTPget.exe file is used to setup and read information from the iServer. This
file can be downloaded from the website listed on the cover of this manual (software
section).

Notes on using HTTPget :
The HTTPget.exe program should be installed to the windows directory (usually c:\winnt

or c:\windows)

1. Open up a command window (or have a DOS window)

a) Click on start menu
b) Click on “Run”
c) In the dialog box that appears, type “cmd” or “command” and click on “OK” button.
d) A command window should now appear.

2. If you now type “httpget” and press the “enter” key, the program options should be

displayed.

3. Next run HTTPget with the options displayed below

httpget -r -S “*SRTC\r” 192.168.1.200:2000

where:

-r –S are parameters needed for the command string
*SRTC is the command:

\r is the carriage return termination character

Appendix A GLOSSARY

User of this manual should be familiar with following definitions:
ARP (Address Resolution Protocol) is a protocol for mapping an Internet Protocol address

(IP address) to a physical machine address that is recognized in the local network. For
example, the IP address in use today is an address that is 32-bits long. In an Ethernet
local area network, however, addresses for attached devices are 48-bits long. (The physical
machine address is also known as a Media Access Control or MAC address.) A table, usually
called the ARP cache, is used to maintain a correlation between each MAC address and its
corresponding IP address. ARP provides the protocol rules for making this correlation and
providing address conversion in both directions.

Ethernet is a network protocol defined by the IEEE 802.3 standard. Ethernet-based
networks use MAC Address rather then IP Address to exchange data between computers.
By using ARP and adding TCP/IP support, Ethernet devices may be connected as part of the
Internet. An Ethernet LAN typically uses coaxial cable or special grades of twisted pair wires.
The most commonly installed Ethernet systems are called 10BASE-T and provide transmission
speeds up to 10 Mbps. Devices are connected to the cable and compete for access using a
Carrier Sense Multiple Access with Collision Detection (CSMA/CD) protocol.

IP (Internet Protocol) is the method or protocol by which data is sent from one computer to
another on the Internet.

IP address (Internet Protocol address) is a 32-bit number that identifies each sender or
receiver of information that is sent in packets across the Internet.

IP Netmask is a 32-bit pattern of bits used to determine which part of the IP address is the
network portion and which part is the host portion.

MAC (Media Access Control) Address is your computer’s unique hardware number. When
you’re connected to the Internet from your computer, a correspondence table relates your IP
address to your computer’s physical (MAC) address on the LAN.

Ping is a utility that tests the network connectivity. It is used to determine if the host is capable
of exchanging information with another host.

Port number/Socket number is a way to identify a specific process to which an Internet or
other network message is to be forwarded when it arrives at a server. It is a predefined address
that serves as a route from the application to the Transport layer or from the Transport layer to
the application of the TCP/IP system.

Sockets are a method for communication between a client program and a server program in
a network and defined as “the endpoint in a connection.” Information transferred across the
Internet primarily occurs between sockets.

SMTP Simple Mail Transfer Protocol is an Internet standard for electronic mail (email) transfer
across the Internet. SMTP clients usually use SMTP to send email messages by specifying the
SMTP server. The email server uses SMTP to both send and receive email messages.

SNMP Simple Network Management Protocol is a network monitoring protocol to monitor
devices connected to an Ethernet Network.

TCP/IP (Transmission Control Protocol/Internet Protocol) is the basic communication
language or protocol of the Internet. When you are set up with direct access to the Internet,
your computer is provided with a copy of the TCP/IP program just as every other computer that
you may send messages to or get information from also has a copy of TCP/IP. TCP/IP often is
used as a general term to indicate generic access to the Internet.

UDP/IP (User Datagram Protocol/Internet Protocol) is the TCP/IP standard protocol that
allows an application program on one machine to send a datagram to an application program
on another.

data to every node on the same network. The Directed UDP transmits data to one node only.

The UDP can be either in Broadcast or Directed form. The Broadcast UDP transmits

Appendix B IP Address

An IP address is a unique 32-bit address assigned to a computer and includes:

a A network ID number identifying a network.
a A host ID number identifying a computer on the network.

All IP addresses have been divided into three smaller groups (classes) A, B and C

a Class A addresses have 8-bits of network ID and 24-bits of host ID. They can support

a large number of hosts, approximately 2 = 16,777,216 computers per network.

The IP addresses range in binary from 00000001.xxxxxxxx.xxxxxxxx.xxxxxxxx

to 01111111.xxxxxxxx.xxxxxxxx.xxxxxxxx

The IP addresses range in decimal from 1.x.x.x to 127.x.x.x

Class A network ID’s support a very large number of hosts.

a Class B addresses have 16-bits of network ID and 16-bits of host ID. They can

support approximately 216 = 65,536 computers per network.

The IP addresses range in binary from 10000000 00000000.xxxxxxxx.xxxxxxxx
to 10111111 11111111.xxxxxxxx.xxxxxxxx

The IP addresses range in decimal from 128.0.x.x TO 191.255.xxx.xxx

Class B network ID’s support a medium number of hosts.

a Class C addresses have 24-bits of network ID and 8-bits of host ID. They can support
approximately 28 = 256 computers per network.

The IP addresses range in binary from 11000000.00000000.00000000.xxxxxxxx
to 11011111.11111111.11111111.xxxxxxxx

The IP addresses range in decimal from 192.0.0.xxx to 223.255.255.xxx

Class C network ID’s support a small number of hosts.

The rest of the addresses are divided into two classes, D and E.
Class D networks are not assigned to the host. They are used for multicasting.
The address range from 224.x.x.x to 239.x.x.x

Class E networks are experimental or reserved addresses.
The address range from 240.x.x.x to 247.x.x.x

57

Appendix C ARP Commands

ARP is the Internet layer protocol responsible for matching or obtaining the MAC
(hardware) address that corresponds to a particular IP address. The ARP command
allows the user to view the current contents of the ARP cache of the local computer
(residing on the same network). Microsoft includes the ARP.EXE utility for viewing and
modifying the ARP cache with its Windows products. The following ARP commands can
be used to view cache entries:

a arp –a  Use this command to view all ARP cache entries.
a arp –a plus IP address  Use this command to view ARP cache entries associated

with one particular interface on a network with multiple adapters.

a arp –g  Same as arp –a.
a arp –N  Use this command to display ARP entries for specific network interface.
a arp – s plus IP address plus Physical address  Use this command to manually

add a permanent static entry to the ARP cache.

a arp –d  Use this command to manually delete a static entry.

Ping the destination computer using IP address first before using the arp -a
command.

The following window shows examples of arp commands and responses.

a Your computer has an IP address of 192.168.1.118
a The destination computer has an IP address of 192.168.1.96

Appendix D IP Netmask

IP Netmask or Subnet Mask is a 32-bit pattern of ones and zeros used to determine
network portion of an IP address from the host portion of the IP address. Subnet mask is
a network ID that is created by borrowing bits from host portion of IP address and using
them as part of a network ID. The table below shows a default subnet mask for address
Classes A, B, and C. Each bit that is set to “1” in the subnet mask corresponds to the bit
in the IP address that is to be used as the network ID. Each bit that is set to “0” in the
subnet mask corresponds to a bit in the IP address that is to be used as the host ID.

If your network requires more network ID’s, you can extend the default subnet mask to
include additional bits from the host ID. This allows for additional network ID’s within the
network. The table below shows some examples of subnet masks and bits moved from
the hosts ID to create a new subnet.

Appendix G Java Runtime Environment Setup

If your computer does not have Java installed, please download from http://java.sun.com.
You can change the Java setting by clicking its icon in Control Panel. To load the applet,
you have to enable the web browser and disable cache.

G.1 Java Runtime Environment 1.7 Setup instructions

1. Go to your computer’s Control Panel. Open the Java Plug-in

Verify that
the path is
correct.

Figure G.1 Java 1.7 Screen Shot

G.2 Browser Proxy Selection

Accessing iServer within your internal network

W Usually when the computer and iServers are on an internal network, you will not use

Proxy server access.

W You should un-check the “Use Browser Settings” option on the “Proxy” tab.

Accessing iServers units using the internet

W Often the web browser will use Proxy server access to the internet. In such cases,

the default Java runtime settings on the “Proxy” tab should suffice. The default
setting is the “Use Browser Settings” option.

W If the default proxy setting doesn’t work, then you may have a situation where the

proxy settings of the web browser are incorrect.

Diagnostics:

If the web page of the iServer appears, then the HTTP Proxy is working fine.
If the data isn’t updated on the iServer upon selecting the “Readings” or “Chart” web

page, there may be a problem with access through a winsock proxy server. In such
cases your network administrator will need to provide the winsock proxy server and port
#s. .

These values should be entered into the Socks line on the “Proxy” tab (of the Java Plugin
control panel) or into the “connections” tab on the View,Internet Options dialog and make
sure that the Proxy tab shows that the “Use Browser Settings” option is not selected (i.e.
when you specify proxy connections in the Java Plugin control panel).

Accessing iServer units over Peer-to-Peer network

A simple peer-to-peer network is setup by disconnecting from the main network (as users
will often do when trying to do initial setup of the iServer) and then connecting the iServer
to another computer using an ethernet hub, an ethernet switch, or a Cross-over cable
connection.

Often when using a peer-to-peer network, the Java plugin and the web browser (such
as Internet Explorer) have internet connections configured to connect through proxy
servers. In such case, you will need to simply assign the final IP address on this peer
to peer network and then view the iServer charts after connecting the iServer into the
regular network. Otherwise you can disable the Java plug-in’s “Use Browser Settings”
temporarily and then reconfigure the Java plug-in settings for regular network access
after testing the iServer chart access on your peer-to-peer network.

The “Use Browser Settings” should not be selected. And the HTTP and Socks proxy
entries should be blank. Also, setup the internet browser so that proxy servers are disabled.

Appendix H Sensor Information

H.1 Accuracy

RH Accuracy Chart Temperature Accuracy Chart

Figure H.1 Figure H.2

Accuracies are tested at Manufacturer’s Outgoing Quality Control at 25°C (77°F) and

3.3V. Values exclude hysteresis and non-linearity, and is only applicable to noncondensing
environments.

H.2 Operating Conditions

Sensor works stable within recommended normal range – see Figure. Long term exposures
to conditions outside normal range, especially at humidity >80%RH, may temporarily offset
the RH signal (+3 %RH after 60h). After return to normal range it will slowly return towards
calibration state by itself. See Section H.4 “Reconditioning Procedure” to accelerate
eliminating the offset. Prolonged exposure to extreme conditions may accelerate aging.

Figure H.3 Normal Range

H.3 Storage Conditions and Handling Instructions

It is of great importance to understand that a humidity sensor is not a normal electronic
component and needs to be handled with care.

Chemical vapors at high concentration in combination with long exposure times may offset
the sensor reading. For these reasons it is recommended to store the sensors in original
packaging including the sealed ESD bag at following conditions: Temperature shall be in
the range of 10°C – 50°C (0 – 80°C for limited time) and humidity at 20 – 60%RH (sensors
that are not stored in ESD bags). For sensors that have been removed from the original
packaging we recommend to store them in ESD bags made of PE-HD8.

In manufacturing and transport the sensors shall be prevented of high concentration of
chemical solvents and long exposure times. Out-gassing of glues, adhesive tapes and
stickers or out-gassing packaging material such as bubble foils, foams, etc. shall be avoided.
Manufacturing area shall be well ventilated.

65

Appendix H Sensor Information (continued)

H.4 Reconditioning Procedure

As stated above extreme conditions or exposure to solvent vapors may offset the sensor. The
following reconditioning procedure may bring the sensor back to calibration state:

Baking: 100 – 105°C at < 5%RH for 10h
Re-Hydration: 20 – 30°C at ~ 75%RH for 12h.

(75%RH can conveniently be generated with saturated NaCl solution. 100 – 105°C
correspond to 212 – 221°F, 20 – 30°C correspond to 68 – 86°F)

H.5 Temperature Effects

Relative humidity reading strongly depends on temperature. Therefore, it is essential to keep
humidity sensors at the same temperature as the air of which the relative humidity is to be
measured. In case of testing or qualification the reference sensor and test sensor must show
equal temperature to allow for comparing humidity readings.

The packaging of sensor is designed for minimal heat transfer from the pins to the sensor.
Still, if the sensor shares a PCB with electronic components that produce heat it should be
mounted in a way that prevents heat transfer or keeps it as low as possible. Furthermore,
there are self-heating effects in case the measurement frequency is too high.

H.6 Light

The sensor is not light sensitive. Prolonged direct exposure to sunshine or strong UV
radiation may age the housing.

H.7 Materials Used for Sealing / Mounting

Many materials absorb humidity and will act as a buffer increasing response times and
hysteresis. Materials in the vicinity of the sensor must therefore be carefully chosen.
Recommended materials are: Any metals, LCP, POM (Delrin), PTFE (Teflon), PE, PEEK, PP,
PB, PPS, PSU, PVDF, PVF. For sealing and gluing (use sparingly): Use high filled epoxy for
electronic packaging (e.g. glob top, underfill), and Silicone.

Out-gassing of these materials may also contaminate the sensor (see Section H.3).
Therefore try to add the sensor as a last manufacturing step to the assembly, store the
assembly well ventilated after manufacturing or bake at 50°C for 24h to outgas contaminants
before packing.
