to the Ethernet network using the TCP/IP protocol. It contains Ethernet and RS232
or RS485 interfaces.
The standard features include:
• Use standard Web Browser, TCP connection, HTTPget DOS program or Telnet
Simulation, for network connectivity.
• Install via RS232/RS485 serial port connection.
Transfer data from RS232/RS485 serial interface to TCP/IP using built-in socket
•
server.
• Use a standard home page for OEM applications.

2.3 Serial Communication Interfaces (For Models with -C4EIT)
The iSeries controller/monitor with Embedded Ethernet Server option supports only
RS485/422 interfaces to slave instruments with RS485 interfaces (ex: i833-C24).
This allows the use of one TCP/IP address assigned to the master unit (-C4EIT) to
communicate with multiple slave units (-C24). See Figure 2.3.
-C4EIT master unit acts as hub (Web Server), but it cannot initiate an outside
connection with RS485. The serial portion of this option is used to slave multiple
RS485 units together using the one IP address of that master unit (-C4EIT).
The RS485 standard (multi-point) allows one or more devices
(multi-dropped) to be connected to the Ethernet Server using a two-wire
connection (half-duplex) +Rx/+Tx and –Rx/-Tx. Use of RS485 communications
allows up to 32 devices to connect to the Web Server with cable length up to
4000 feet long.
Although the RS485 is commonly referred to as a "two wire" connection,
the Web Server also provides a ground/return shield connection to use as
a common connection for EMI noise protection.
Table 2.2 shows some characteristics of the RS485 communication interface.
Table 2.2 Data Transmission Characteristics RS485
Data Transmission Characteristics RS485
Transmission Mode Differential
Electrical connections 2 wire
Drivers per line 32 drivers
Receivers per line 32 receiver
Maximum cable length 4000 ft (1200 meters)

2.3.1 Wiring Master/Slave Units via RS485 Interface
RS485 interface uses a two-wire communication system (one for transmitting and one for
receiving) plus a common wire to connect to the shield of the cable. It is recommended
to use a shielded cable with one twisted pair.
Use of twisted pair and shield will significantly improve noise immunity.
Figure 2.3 shows multi-point, half-duplex RS485 interface connections for the iServer.
Figure 2.2 Multi-point, Half-Duplex RS485 Wiring
Value of the termination resistor is not critical and depends on the cable
impedance.
Table 2.3 shows RS485 half-duplex hookup between the iServer serial port and device
with RS485 communication interface.

2.4 Network Communication Interfaces
2.4.1 10BASE-T RJ-45 Pinout
The 10BASE-T Ethernet network system is used in the iServer 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.
Pin Name Description
1 +Tx + Transmit Data
2 -Tx - Transmit Data
3 +RX + Receive Data
4 N/C Not Connected
5 N/C Not Connected
6 -Rx - Receive Data
7 N/C Not Connected
8 N/C Not Connected
Figure 2.3 RJ-45 Pinout
2.4.2 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”.
You may need to power recycle for auto detect to take place.

PART 3
NETWORK CONFIGURATION
3.1 Network Protocols
The iServer can be connected to an Ethernet network using standard IP protocols
including TCP, UDP, SNMP, SMTP, ARP, HTTP (WEB server), DHCP, DNS, Telnet,
and Modbus TCP/IP.
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 thru Figure 3.3.
Figure 3.1 i8 - Labeling
Figure 3.3 i16 - Labeling
Figure 3.2 iDR - Labeling
8
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 iServer, as soon as the iServer is connected to the
network, there is an exchange of information between the iServer and the DHCP
server. During this process the IP address, the Gateway address, and the Subnet
Mask, will be assigned to the iServer by the DHCP server. Note that the DHCP
server must be configured correctly to do such assignment.
The iServer is shipped with DHCP disabled (factory default).
If fixed or static IP address is desired, the DHCP function must be disabled.
The DHCP can be enabled by accessing the iServer’s web server and selecting
Network option (refer to Section 4.5.2).
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 iServer.
2. The iServers 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’s
very important to configure 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.
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://eit0a0b or any eight character name stored as Host Name under
Access Control menu in the iServer Home Page.
The default DNS name for an iServer is "eit" followed by the last four digits of the
MAC address of that particular iServer.
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 itself and the
serial device connected to the iServer’s serial port. 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.
9
3.6 TCP Port (Socket) Number
All TCP connections are defined by an 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.
There are three default TCP port (socket) numbers assigned to the iServer:
1. Port 1000: Once a TCP connection is made to the iServer using port 1000, the
iServer will forward the connection to the serial device and it will take the
response from the serial device and send it out to the network.
2. Port 2000: Once a TCP connection is made to the iServer using port 2000 (or
any port number that is configured on the iServer), the iServer will forward the
connection to the serial device and it will take the response from the serial
device and send it out to the network.
3. Port 2002: This port is the iServer’s network console port for reading or
changing the iServer’s settings. This can be done using a Telnet application.
Example: C:\>Telnet 192.168.1.200 2002
10
PART 4
OPERATIONS
This iServer can be configured in several ways, depending on user’s preference and
network setup. It can be configured using a Web browser like Chrome, Internet Explorer,
or Firefox to access its Web server. It can also be configured using a TCP connection to
port 2002 using a command line interface. The iConnect Configuration Software can also
be used to find and configure the iServer over the Ethernet.
4.1 SERIAL INTERFACE CONFIGURATION - Communication Protocol
A data communication protocol defines the rules and structure of messages used by all
devices on a network for data exchange. A typical transaction will consist of a request to
send from the MASTER followed by the response from one or more SLAVE devices.
Either a single (point-to-point) or multi-drop network (multi-point) is possible.
4.2 Command Structure
There are different command types associated with communication between the
Ethernet Server and your device shown in Table 4.1, which shows the Command Prefix
Letters (Command Classes)
Table 4.1 Command Prefix Letters
COMMAND PREFIX
(COMMAND CLASS) MEANING
^AE Special read, Communication parameters
P (Put) Write HEX data into RAM
W (Write) Write HEX data into EEPROM.
G (Get) Read HEX data from RAM
R (Read) Read HEX data from EEPROM
U Read status byte
V Read measurement data string in decimal format
X Read measurement data values in decimal format

Where:
"*" is the selected Recognition Character. You may select any ASCII table symbol from
"!" (HEX address "21") to the right-hand brace (HEX "7D") except for the caret "^", "A",
"E", which are reserved for bus format request.
"ccc" stands for the hex-ASCII Command Class letter (one of eleven given in Table 4.1),
followed by the two hex-ASCII Command Suffix characters identifying the meter data,
features, or menu items to which the command is directed.
"<data>" is the string of characters containing the variable information the computer is
sending to the meter. These data (whether BCD or binary) are encoded into hex-ASCII
character (see Appendix D for binary-hex-ASCII chart), two characters to the byte.
Square brackets [indicating optional status] enclose this string, since some commands
contain no data.
"<nn>" are the two ASCII characters for the device Bus Address of RS485
communication.
Use values from "00" to hex "C7" (199 decimal).
The following format is used for each byte sent and received through serial port of
Ethernet Server:
1. Seven or Eight-bit binary, Hexadecimal (0 ... 9, A ... F)
2. Two hexadecimal characters contained in each eight-bit field of the message
3. 1 start bit; 7 or 8 data bit; 1 Stop Bit; Odd, Even (No Parity) Bit
The figure below shows the bit sequences when a byte is transmitted or received
through the Ethernet Server.
LSB MSB

4.4 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 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.
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 above.
To verify a good connection to the iServer, from a DOS prompt on your computer
type “ping 192.168.1.200” and press Enter. You should get a reply as shown in
Figure 4.1.
Figure 4.1 Pinging the iServer from a DOS Prompt
13
4.5 Access and Configuration Using a Web Browser
• Start your web browser.
• In the URL field, type http://192.168.1.200 (iServer’s default IP address)
• The iServer will display the LOGIN page, as shown below.
Figure 4.2 iServer LOGIN Page
In order to access iServer’s web pages, users may be prompted for a
password.
Figure 4.3 iServer LOGIN and ADMINISTRATOR Passwords
There are two different access levels:
1. LOGIN Password is required to access the iServer’s web server unless it’s
disabled. The default password is 12345678. This password can be up to 16
alphanumeric case-sensitive characters.
2. ADMINISTRATOR Password is required to access NETWORK, SECURITY, and
SYSTEM web pages, unless it’s disabled. The default password is 00000000.
This password can be up to 16 alphanumeric case-sensitive characters.
14
4.5.1 Overview
Once the LOGIN password is entered, the OVERVIEW page will appear which
provides a summary of important parameters within the iServer.
All the fields are read-only.

15
4.5.2 Network
This page provides configurations for the Ethernet interface and TCP/IP parameters.
Fields are described below.
Figure 4.5 iServer NETWORK Page
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.
MAC Address – This Indicates the hardware address of the iServer and it’s 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.
16
4.5.2 Network (continued)
Subnet Mask – 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.
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 iServer’s DNS feature, the DNS server on your
network must be configured. That allows the iServer to use a host’s domain name to
access the Ethernet node. The 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 gateway address.
Host Name – If the DHCP is enabled the iServer will send this name to the DHCP
server. This name is used so 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://eit0a0b or any name up to eleven alphanumeric
characters. The default Host Name for an iServer is "eit" followed by the last four
digits of the MAC address of that particular iServer.
On Windows servers where the DHCP and DNS are separate functions it’s
very important to configure the DHCP server to communicate with the 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.
Protocol – It’s the network protocol the iServer communicates with the Ethernet
Network. Options are TCP, UDP, and ModbusTCP. The default is TCP.
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 (:) after the IP address. For example, if the Web
Server Port is 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.

4.5.3 Serial (RS485 Serial Port)
These pages provide configurations for the iServer’s serial port as well as different
techniques for bridging data between serial and Ethernet ports (see Figures 4.6
through 4.10). Fields are described below.
The RS485 Service Port Tab as shown in Figure 4.6 will appear only for
option C4EIT.
For the iSeries EIT option the following parameters: 9600,O,7,1,none are
fixed and the device must be set to these parameters.
For EIT option there will be no tab.

Baud Rate – This indicates the speed of the iServer’s serial port. Options are 300,
600, 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200, 230400, and 460800
bits/s. The default is 9600 bits/s.
iSeries device maximum Baud Rate is 19.2 kb/s
Data Bits – This indicates the number of bits in a transmitted serial packet. Options
are 7 and 8. The default is 7.
Parity – This checks the serial packet for the parity bit. Options are Even, Odd, and
None. The default is Odd.
Stop Bit – This indicates the end of transmission. Options are 1 and 2. The default is 1.
Flow Control – This handles the data flow between the iServer and the attached serial
device to ensure it’s processed efficiently. Too much data arriving before the device
can handle it causes lost data. Options are Software also called Xon/Xoff (using Tx
and Rx pins), and None. The default is None.
