Introduction
1.1 About Ethernet Adaptor (EAD01-103) - Overview
EAD01-103 is a Device that converts RS-232 serial data into TCP/IP protocol. It enables
remote gauging, managing and control of a Serial Device through the network based on
Ethernet and TCP/IP by connecting to the existing equipment with RS-232 serial
interface. In other words, EAD is a protocol converter that transmits the data sent by
Serial equipment as TCP/IP data type and converts back the TCP/IP data received
through the network into serial data to transmit back to the equipment. EAD01-103 also
supports UDP Protocol for Broadcast kind of application.
The EAD01-103 allows you to network-enable a variety of serial devices that were not
originally designed to be networked. This capability brings the advantages of remote
management and data accessibility to thousands of serial devices over the network.
The EAD01-103 is the low cost Serial RS 232 to Ethernet LAN 10/100 Mbps
connectivity system using the TCP/IP protocol and based on a cold fire high speed 32-bit
microprocessor. It is having built in web server. The EAD01-103 supports RS 232 serial
communication allowing virtually any asynchronous serial connectivity device to be
accessed over a network. Some models do Support RS 485 and RS 422 connectivity as
add-on feature.
As for the Internet connectivity, the EAD01-103 supports open network protocols such as
TCP/IP allowing Serial Devices to be accessed over broadband network or conventional
LAN (Local Area Network) environment.
The EAD01-103 provides the management console using Web Browser, Telnet and Serial
console port under the password protection support. The EAD was designed to
accommodate the unique requirements of the Retail POS, Security, Automation and
Medical marketplaces.
Parts of this manual assume the knowledge on concepts of the Internetworking protocols
and serial communications. If you are not familiar with these concepts, please refer to the
standards or the documentation on each subject.
1.2. Network Protocol
The EAD01-103 uses IP protocol for network communications. For network connections
to the Serial port TCP, UDP, ICMP, MAC, DHCP and Telnet protocols are used.
1.2.1. Ethernet Address or MAC Address
The Ethernet adaptors have what is known as Hardware address or MAC address. It has
its own addressing scheme based on a unique six-byte address. This is generally called
Media Access and Control (MAC) address.
One example of Ethernet Address is given below:
00-17-85-01-36-0C or 00:17:85:01:36:0C

1.2.2. Internet Protocol (IP) Address
To identify an individual computer/device on the IP network, the device must have a
unique IP address in a Network. The current version of Internet Protocol uses a four-byte
number, expressed in dotted decimal notation.
Sample IP Address
192.168.0.250
1.2.3. Port Number
Every TCP connection is established using a destination IP address and a Port number.
For example Telnet application commonly uses port number 23 of contacted IP number.
The EAD‟s Serial channel (port) can be associated with a specific TCP or UDP Port
number. E.g. Port number 7727 (as source port number)

you will have to use > open 192.168.0.254 7353 after issuing Telnet command in the Run.
5.3. Auto IP Programming
If the user knows only the MAC address of the EAD and doesn‟t know the IP address
then you can program it by adding “arp” (Address resolution Protocol) entry in his
Computer and then connect through telnet using that IP and port number 7353.
For adding the “arp” entry, go to the DOS or Command prompt in your PC and enter the
IP and MAC address as below.
C:\> arp –s [IP address] [MAC Address]
For example: -
Figure. 8. Auto IP Programming using arp
Once the Arp entry is added, try to ping the EAD using the command:
Ping [IP address] –l 102
and ensure the ping response is successful.
You can now program the EAD through Telnet program. Enter the Host Name as the IP
that you set in your system ARP table, and the Port should be 7353.

Parameter Description
7.1. Network Configuration.
Under the Network configuration there are eight parameters, which are programmable.
The parameters are explained below.
7.1.1. IP Address.
The IP address must be set to a unique value in your network. (See section 1.2.2). The
EAD cannot connect to the network if the assigned IP address is already in use by any
another device. Default is 192.168.0.254
Example:-192.168.0.250.
Please do set the IP number to 0.0.0.0, if you wish the EAD to acquire IP number
from DHCP Server in your Network automatically.
7.1.2. Netmask.
A netmask defines the number of bits taken from the IP address that are assigned for the
host section. Default is 255.255.255.0
Example: - 255.255.255.0
7.1.3. Gateway.
The Gateway or Router allows communication to other LAN segments. The gateway
address should be the IP address of the router connected to the same LAN segment. The
gateway address must be within the local network address range. There is no default
value.
Example: - 192.168.0.XXX
7.1.4. Port Number.
This setting represents the port number for TCP connections to the serial device. Once the
IP number is selected and the port number is opened then the serial device becomes
transparent for data Transfer. Default value is 7727. You can select values from 1 to

7.2.3. Flow Control
Flow control is required for handshake with the Serial device for stopping serial data
input/output to avoid character loss. Supported options are NONE for No Flow control,
XON/XOFF for Software Flow control and RTS/CTS for Hardware Flow control.
Default None
It is highly recommended to use Flow control for higher Serial speed applications.
7.2.4 Serial I/F Mode
EAD supports RS232 (Default), RS485 (2 Wire) and RS422 (4 Wire) Serial port
Interface characteristics based on the option and need of the customer. The same is
enabled in the option when the Hardware is supported in the unit.
7.2.5. Character Wait Timeout
Character wait time out defines how long the EAD should wait before sending
accumulated serial characters to network. Serial data arrives at EAD, which is packetized
and sent through the LAN after this period. Set this to smaller value for immediate
transfer. Default is 0 Milliseconds. You can set this up to 254 milliseconds
7.2.6. Inter Character Delay
Inter Character delay is the delay between two characters from the EAD to the serial port
/ device. The range is from 00 to maximum of 254msec.Default 0 milliseconds. Higher
Inter- Character delay is selected if the device can receive the serial character only with
delay between characters.
7.2.7. Connection Status Reporting
Once EAD establishes connection with the Remote Server Machine in Auto Mode or
based on number of Characters, the user can be intimated with a connect Message. This
reporting of connection status can be Enabled or Disabled. (Default - Disabled). When
Enabled with Option 1, CONNECTED message is displayed when socket connection is
successful in port 7727 and DISCONNECTED message when the connection drops. The
Status reporting does not happen when there is Passive or Connection from Server takes
place.
7.2.8. XON XOFF Pass through
XON XOFF pass through when is enable we can send the data to server, Default Setting
is Disable.
7.2.9. Exit

7.3. Server Configuration
Under Server Configuration various parameters required for EAD to connect to Server
are provided and the available options are described below.
7.3.1. IP Filtering
This innovative and useful option is available under Server Configuration. The main
purpose of the same is ensure that only the relevant or select computers in the Network
connects or communicates to the EAD and prevents all other computers in the Network
interfering or intruding in its operation.
There are entries for 5 IP numbers under this menu. When all of them are set to 0.0.0.0,
the IP Filtering option is Disabled (Default).
Entry of the IP number or numbers in this option enables this Feature and ensures that
only the computers or devices with these IP number can Ping, Telnet to ports 7353 or
7727 and use browse interface. For all others, these operations will not be permitted.
Note:
1. Please note that once this is set, the EAD Will be accessible (even for ping) only from
the PC having that IP address
2. There is one exception to this in case of forgotten IP numbers in the list. The IP
number 192.168.0.1 is the only IP permitted always even if it is not set in the IP Filter
table.
Do make a note of the following points:
1. If the unit is set with Gateway IP address, you should add the same in IP Filter list.
2. If you are setting the EAD to Auto connect to Server on Power-up or based on
input characters, then the Server IP should be added to this list.
7.3.2. Start Mode
There are three types of start modes available. 0 for Auto start, 1 for Manual mode and 2
for Input character.
Auto Start: - This mode is selected when you want EAD to automatically connect on
Power Up to a Server in Network running any application listening for incoming
connections. The connection parameters like the Remote IP address and the TCP port
number parameters have to be configured and saved for this. If Automatic connection
method is selected (here you can program the time to get connected after switching on the
unit also), all parameters must be provided. (i.e. Remote IP, Remote port number, Start
mode = 0). It will connect to the programmed IP address and the port number according
to the time programmed. Waiting time rage from 1-999 seconds. The Default time is 60
Seconds.
It is not possible to set waiting time through web browser.
Manual Mode: - In the manual mode, TCP connection can be made by entering
command from Terminal or Serial port as:
