1. Introduction
The ED-10 TCP is an Industrial Ethernet Adapter a ting as a serial server. The type of
serial interfa e is sele table between RS-232 and RS-422/485. The Ethernet interfa e is
10BASE-T and TCP/IP Proto ols are implemented for network ommuni ation.
The ED-10 TCP provides a remote serial interfa e for a omputer onne ted through a
TCP/IP network.
To omplete the onne tion to the ED-10 TCP additional software need to be used in
the omputer. Different solutions are possible, e.g.:
1. Telnet to the ED-10 TCP.
All keystrokes are trans-
ferred to the remote seri-
al interfa e.
Any hara ters re eived at
the remote serial interfa e
are transferred to the
omputer s reen.
2. A COM port redire tor
software an be used to
reate up to 256 virtual
COM ports.
This software will redire t
data, originally sent to a
lo al COM port, to the remote serial inter-
fa e of the ED-10 TCP. No hange of om-
puter appli ation software is then ne essary.
3. Customer written software an be used to
dire tly a ess the network interfa e (so ket
ompliant) of the ED-10 TCP.
A sample written in C++ an be found on
the CD ”\Software\Sample\sample.zip”

The ED-10 TCP 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 enhan ed surge/transient prote tion.
The ED-10 TCP is approved for Industrial EMC Immunity and Emission .
The ED-10 TCP 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 net-
works 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 TCP uses TCP for remote onfiguration ( onfiguration mode) and for the
serial server appli ation.
The ED-10 TCP 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
General:
Before using this unit,read the manual completely and comply with information
on the unit,and make sure that you understand it fully.Check that your applica-
tion does not exceed the safe operating specifications for this unit.
Before installation, maintenance or modification work:
Prevent damage to internal electronics from electrostatic discharges (ESD) by dis-
charging your body to a grounding point (e.g.use of wrist strap).
Installation:
This unit is constructed for professional system use.It should be located in a
restricted access area,such as locked cabinet which can only be accessed by serv-
ice personnel.
Sound installation practice, as defined by applicable local codes or regulations,shall
be followed in every instance in which such practice is applicable.
This unit is defined as class III equipment and shall be separated from hazardous
voltage by double or reinforced insulation.
All interfaces must only be connected to SELV orTNV-1 circuits.

5.3 Configuration
5.3.1 DIP switch settings
DIP-switches used to configure the modem are accessable under the lid
on top/front of the unit.
Warning!
Prevent damage to internal electronics from electrostatic discharges (ESD)
by discharging your body to a grounding point (e.g.use of wrist strap),
before the lid on top of the modem is removed.
Warning! Do not open connected equipment.
Prevent access to hazardous voltages by disconnecting the unit fromAC/DC
mains supply and all others electrical connections.
NOTE! When configuration via DIP-switches, the
settings of DIP-switches configure the unit
only after a power reset. A setting
configured by any other method
during normal operation,override
the DIP-switch setting. However,
at power up,the DIP-switch set-
tings have precedence over the
setting configured by any other
method.

176609-2211
6. Functional description
The ED-10 TCP an be in either onfiguration ( onfig) mode or in appli ation (app) mode.
Normally the ED-10 TCP is in app mode, where the serial server is enabled and all onfig-
uration settings are readable.
Change of onfiguration parameters are done in ED-10 TCP onfig mode.
Configurable parameters are listed in hapter 7.3.
Application mode
In appli ation mode the ED-10 TCP a t as a serial server. After reboot it awaits a remote
lient to make a TCP onne tion. When the onne tion is established all data re eived at
the network interfa e will be 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 at the network interfa e to the remote
lient. Please note that the TCP proto ol allows network pa kets to be split or lumped
together, hen e override the pa king algorithm. The default pa king algorithm shall nor-
mally remain un hanged.
When a TCP onne tion is losed the ED-10 TCP an be set to optionally (mode 2)
transmit a TCP RST message to the lient.
The TCP onne tion is losed by the remote lient, any network error or by CH1 DTR
(if DTR ontrol, mode 1, is a tivated).
In DTR ontrol mode no onne tions will be established as long as DTR is de-a tivated.
ED-10 TCP an be onfigured to a ept one spe ifi or all remote lient IP addresses.
If all remote lients are a epted an established onne tion will be losed by a new on-
ne tion request. This will allow a redundant SCADA ontroller to "overtake" an already
established onne tion.
Hardware topology

18 6609-2211
The ED-10 TCP network performan e an be optimized for minimum delays or minimum
network loading. By default it is optimized for minimum delays, whi h is the re ommend-
ed setting under normal onditions. But for transfer of large amount of ontinuous data at
high serial data rate it is re ommended to use mode 4 whi h is optimized for maximum
throughput and minimum network loading.
Server status information is always available, lo ally at serial CH2 or remotely by a telnet
onne tion to port 23.
The pa king algorithm an be onfigured 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.
The serial server and remote lients are identified by IP address and proto ol number.
Configuration mode
Lo al or remote onfiguration is managed by either a terminal programme or by ED-Tool.
ED-Tool is a Windows based setup 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 TCP 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 TCP
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.

7. Configuration
7.1 Configuration by ED-Tool
ED-Tool is intended to be used with a number of products.
This section describes ED-Tool program start and configuration of the ED-10TCP using
the ED-Tool program.
Before read, write or reboot an be made, Sele t type of onne tion.
• Network
• Serial om port must be sele ted from menu ’Tools – Serial – Port’
•When reading configuration from attached unit the type specific (ED-10TCP)
property tab will automatically selected and the field ’Type’in the Staus bar shows the
identity (ED-10TCP) of the attached unit.
•When writing configuration to attached unit the valid type specific (ED-10TCP)
property tab shall be selected and none of the parameter fields shall be left empty.

20 6609-2211
Program Start:
To start ED-Tool
•Locate ED-Tool under Program on theWindows Start Menu.
•Click on the ED-Tool icon
•Or locate the ED-Tool icon on the desktop
After the ED-Tool has been successful opened the user is presented with an empty
configuration screen.The user can now get an existing configuration by reading the
configuration from an ED-10TCP or by opening a configuration file stored on the
system.Or the user can set all configuration parameters by hand.
To configure an ED-10TCP the user must set all parameters.After the parameters are
set the user can write the configuration to the ED-10TCP.
Typical configuration procedures:
•Read configuration from an ED-10TCP
