1.2 Description

This iServer is designed to connect industrial devices with serial interfaces to the
Ethernet network using the TCP/IP protocol. It contains an Ethernet Server interface.

The standard features include:

• Use standard Web Browser (TCP/IP protocol), HTTPGET DOS program or Telnet
Simulation, for network connectivity.

• Use a standard home page or customize web page for OEM applications.

For this Ethernet Option, the Communication Menu is only used for internal
interface with the Ethernet Option. There is no RS-232 or RS-485 for the user
to access. The setting in the Communication Menu should be: 9600 baud rate,
1 stop bit, odd parity and RS-232. For the server side, the settings would be
the same.

The following example illustrates how you can hookup the devices with serial interface
on the net using the iServer:

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 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.

Figure 2.4 RJ45 Pinout

2.4.2 10Base-T Crossover Wiring

When connecting the iServer directly to the computer, the transmit data pins of the
computer should be wired to the receive data pins of the iServer, and vice versa. The
10Base-T crossover cable with pin connection assignments are shown on Figure 2.5.

Figure 2.5 10Base-T Crossover Cable Wiring

Use straight through cable for connecting the iServer to an Ethernet hub.
The ports on the hub are already crossed.

NETWORK CONFIGURATION

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.

3.3 DHCP

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 iServer, as soon as the iServer is connected to the network, there is an exchange of
information between DHCP server and the iServer. 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.

If fixed or static IP address is desired, the DHCP must be disabled. The iServer is
shipped with DHCP disabled (factory default). The DHCP can be enabled by setting the
DIP switch # 3 to the “ON” position.

Figure 3.2 DIP Switch on the iServer

3.4 DNS

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 Access Control menu in the
iServer Home Page. The default DNS name for an iServer is "eis" followed by the last
four digits of the MAC address of that particular iServer.

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 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 Novell networks or Windows 2000 where the DCHP is an updated
function of DNS this feature may be beneficial since a particular name can be
assigned eliminating the need for the IP address, as described in Section 3.4.

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’s serial port. 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.

3.5.1 Default IP Address

The iServer 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 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 the factory default address is already in use on your network, use an Ethernet
crossover cable between your computer and the iServer and modify 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 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 iServer:

1. Port (socket) number 1000 when using HTTPGET program.

2. Port (socket) number 2000 when trying to access your serial device connected to
the serial port of the iServer.

3. Port (socket) number 2002 when trying to access the iServer itself for reading or
changing the settings. This can be done using Telnet application.

Example: C:\>Telnet 192.168.1.200 2002

PART 4

OPERATIONS

An industrial device with serial interfaces (PLC, CNC controllers, PC, Data Display
Devices, etc.) can be connected to the serial port of the Web Server.

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
D Disable

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.
