1.2 Description

This iServer board can be purchased as a stand alone unit, or as an option
for an iLD monitor/controller (Embedded Ethernet iServer) with a RS485
communication port interface. Some iLD Big Display monitors/controllers
do not utilize RS485 communications. In such models, the RS485
instructions do not apply.

The Embedded Ethernet Server is designed to connect industrial devices with serial
interfaces to the Ethernet network using the TCP/IP protocol. It contains an Ethernet
Server and RS-485/422 interfaces.

The standard features include:

• Use standard Web Browser, TCP connection, HTTPGET DOS program or Telnet
Simulation for network connectivity.

• Install via RS-485/422 serial port connection.

• Transfer data from RS-485/422 serial interface to TCP/IP using built-in socket server.

• Use a standard home page or customize web page using special applets, which are
available on our Web site.

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

2.4 Serial Communication Interfaces (For Models with RS485 Port)

The iLD Big Display controller/monitor with the Embedded Ethernet Server option board
support only RS485/422 interfaces. These standards define the electrical characteristics
of a communication network. The RS485 port of the Ethernet Server is fully compatible
for use with RS422 instruments. The RS485 is an extended version of the RS422
communication standard which increases the allowable number of devices from 10 to
32 by improving the electrical characteristics.

• 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 data rate 10M bits/s
Maximum cable length 4000 ft (1200 meters)

2.4.1 Wiring 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 2.3 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.

2.5 Network Communication Interfaces

2.5.1 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

2.5.2 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.

PART 3

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
