1. Introduction
The ED-10 is an Industrial Ethernet Adapter with a serial interfa e. The type of serial
interfa e is sele table between RS-232 and RS-422/485. The Ethernet interfa e is
10BaseT and TCP/IP Internet Proto ols are used for network ommuni ation.
Two ED-10 units an be used to provide a serial point to point link over a TCP/IP net-
work. Ea h ED-10 passes data from its serial interfa e to the other unit's serial interfa e.
This enables long distan e serial onne tions over pre-existing networks.
It is also possible to ommuni ate one to many (e.g. master/slaves), by using a broad-
ast address.
If the ustomer writes it’s own PC appli ation software, the network interfa e of ED-10
an be dire tly a esed.
A software example an be downloaded from the Westermo web site
(www.westermo.se). This example demonstrates how a PC sends network data dire tly
to the ED-10. Sour e ode, in C, is in luded.

The ED-10 is ideal for use in the industrial environment. It is housed in the Westermo
DIN rail box and has a wide range power input, isolated interfa es and transient prote -
tion.
The ED-10 is approved for Industrial EMC Immunity (EN50082-2) and EMC Emission
(EN50081-1). All relevant requirements of the Low Voltage Dire tive are fulfilled.
The ED-10 uses the TCP/IP Internet Proto ol Suit (TCP/IP) to transfer data over the
network.
TCP/IP is a set of proto ols that enables ommuni ation a ross lo al and wide area
networks and in ludes proto ols su h as TCP, UDP, IP , ARP, RARP, ICMP. Although
not all these proto ols are needed for a network data transfer.
The ED-10 uses TCP for remote onfiguration ( onfiguration mode) and UDP for
transmitting the serial data over network, i.e. UDP is used in appli ation mode.
UDP uses pa ket delivery of data, meanwhile TCP uses stream transport.
The ED-10 an be onfigured both remotely over the TCP/IP network and lo ally via the
RS-232 interfa e, making the unit very flexible.
Lo al or remote onfiguration is a hieved either by using the ED-Tool Windows‚ soft-
ware or by using a terminal programme (e.g. HyperTerminal for lo al onfiguration or
Telnet for remote onfiguration).
A DIP swit h setting also allows the unit to be reset to fa tory default, if required.
2. Safety
Serial interfa e CH1 is not isolated from CH2. They must only be onne ted to SELV
ir uits.
The Network interfa e must only be onne ted to TNV or SELV ir uits.
See EN 60950:1996 for definitions.
Sound installation pra ti e, as defined by appli able lo al odes or regulations, shall be
followed in every instan e in whi h su h pra ti e is appli able.

5. Functional description
The ED-10 an be in either onfiguration ( onfig) mode or in appli ation (app) mode.
Normally the ED-10 is in app mode, where the serial-to-network onversion is enabled
and all onfiguration settings are readable.
Change of onfiguration parameters are done in ED-10 onfig mode. Configurable
parameters are listed in hapter 6.4.
Application mode
In appli ation mode the ED-10 transfers data between the serial interfa e (CH1) and the
network interfa e (10BaseT).
At the network interfa e data are re eived as datagrams (network pa kets). Ea h re eived
network pa ket is immediately transmitted at the serial interfa e CH1.
Data re eived from the serial interfa e CH1 is buffered into a data frame a ording to the
pa king algorithm. Ea h frame is then transmitted as a datagram at the network interfa e.
Hardware topology

156609-2202
The pa king algorithm an be onfigurated to transmit data immediately or buffer data
until a transmit requirement is fulfilled. The transmit requirement depend on re eived
data at serial interfa e CH1 and an be:
1. An end of frame hara ter is re eived.
2. An end of frame delay has elapsed sin e last re eived hara ter.
3. A maximum number of bytes have been re eived.
Re ommended onfiguration of the pa king algorithm an be found in the sample appli a-
tions hapter.
When the ED-10 is used in pairs, to establish a serial point to point onne tion over
network, ea h point is identified by its IP address and proto ol port number.
One points lo al identity must mat h with the other points Remote identity, i.e there
is a " ross-relation" between the two points identities.
It is also possible to ommuni ate one to many (e.g master/slave), by using a broad ast
IP address (e.g. 255.255.255.255). Both dire ted and limited broad ast is supported.
Configuration mode
Lo al or remote onfiguration is managed by either a terminal programme or by
ED-Tool.
ED-Tool is a Windows based set-up programme whi h provides easy onfiguration.
Configuration is also possible by using terminal programmes (e.g HyperTerminal for
lo al onfiguration or Telnet for remote onfiguration). A hardware swit h ensures
restore of default settings.
Config mode will be entered; automati ally by ED-Tool, manually by terminal programme
or when power is swit hed on with restore default setting swit h set.
First time onfigure: ED-10 is shipped with IP-address 10.0.0.10.
Please make sure that 10.0.0.10 is ompliant to your network,
before ED-10 is onne ted. Otherwise use serial interfa e to lo ally
set a valid IP address.
A valid IP-address must be ompliant with the network in use and not hosen arbitrarily,
ask your network administrator when in doubt.

6. Configuration
6.1 Configuration by ED-Tool
This se tion des ribes onfiguration of the ED-10 using the ED-Tool program.
After the ED-Tool has been su essful opened the user is presented with an empty on-
figuration s reen. The user an now get an existing onfiguration by reading the onfigu-
ration from an ED-10 or by opening a onfiguration file stored on the system. Or the
user an set all onfiguration parameters by hand.
To onfigure an ED-10 the user must set all parameters. After the parameters are set
the user an write the onfiguration to the ED-10.
Typi al onfiguration pro edures:
• Read onfiguration from an ED-10
• Change some parameters
• Write onfiguration to the ED-10
• Done
or
• Read onfiguration from a file
