1. Introduction
The ED-10 TCP is an Industrial Ethernet Adapter acting as a serial server. The type of
serial interface is selectable between RS-232 and RS-422/485. The Ethernet interface is
10BASE-T and TCP/IP Protocols are implemented for network communication.
The ED-10 TCP provides a remote serial interface for a computer connected through a
TCP/IP network.
To complete the connection to the ED-10 TCP additional software need to be used in
the computer. Different solutions are possible, e.g.:
1. Telnet to the ED-10 TCP.
All keystrokes are transferred to the remote serial interface.
Any characters received at
the remote serial interface
are transferred to the
computer screen.
2. A COM port redirector
software can be used to
create up to 256 virtual
COM ports.
This software will redirect
data, originally sent to a
local COM port, to the remote serial interface of the ED-10 TCP. No change of computer application software is then necessary.
3. Customer written software can be used to
directly access the network interface (socket
compliant) of the ED-10 TCP.
A sample written in C++ can 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
interfaces and enhanced surge/transient protection.
The ED-10 TCP is approved for Industrial EMC Immunity and Emission .
The ED-10 TCP uses the TCP/IP Internet Protocol Suit (TCP/IP) to transfer data over
the network.
TCP/IP is a set of protocols that enables communication across local and wide area networks and includes protocols such as TCP, UDP, IP , ARP, RARP, ICMP. Although not
all these protocols are needed for a network data transfer.
The ED-10 TCP uses TCP for remote configuration (configuration mode) and for the
serial server application.
The ED-10 TCP can be configured both remotely over the TCP/IP network and locally
via the RS-232 interface, making the unit very flexible.
Local or remote configuration is achieved either by using the ED-Tool Windows‚ software or by using a terminal programme (e.g. HyperTerminal for local configuration or
Telnet for remote configuration).
A DIP switch setting also allows the unit to be reset to factory default, if required.

176609-2211
6. Functional description
The ED-10 TCP can be in either configuration (config) mode or in application (app) mode.
Normally the ED-10 TCP is in app mode, where the serial server is enabled and all configuration settings are readable.
Change of configuration parameters are done in ED-10 TCP config mode.
Configurable parameters are listed in chapter 7.3.
Application mode
In application mode the ED-10 TCP act as a serial server. After reboot it awaits a remote
client to make a TCP connection. When the connection is established all data received at
the network interface will be immediately transmitted at the serial interface CH1. Data
received from the serial interface CH1 is buffered into a data frame according to the
packing algorithm. Each frame is then transmitted at the network interface to the remote
client. Please note that the TCP protocol allows network packets to be split or clumped
together, hence override the packing algorithm. The default packing algorithm shall normally remain unchanged.
When a TCP connection is closed the ED-10 TCP can be set to optionally (mode 2)
transmit a TCP RST message to the client.
The TCP connection is closed by the remote client, any network error or by CH1 DTR
(if DTR control, mode 1, is activated).
In DTR control mode no connections will be established as long as DTR is de-activated.
ED-10 TCP can be configured to accept one specific or all remote client IP addresses.
If all remote clients are accepted an established connection will be closed by a new con-
nection request. This will allow a redundant SCADA controller to "overtake" an already
established connection.
Hardware topology
18 6609-2211
The ED-10 TCP network performance can be optimized for minimum delays or minimum
network loading. By default it is optimized for minimum delays, which is the recommended setting under normal conditions. But for transfer of large amount of continuous data at
high serial data rate it is recommended to use mode 4 which is optimized for maximum
throughput and minimum network loading.
Server status information is always available, locally at serial CH2 or remotely by a telnet
connection to port 23.
The packing algorithm can be configured to transmit data immediately or buffer data until
a transmit requirement is fulfilled. The transmit requirement depend on received data at
serial interface CH1 and can be:
1. An end of frame character is received.
2. An end of frame delay has elapsed since last received character.
3. A maximum number of bytes have been received.
The serial server and remote clients are identified by IP address and protocol number.
Configuration mode
Local or remote configuration is managed by either a terminal programme or by ED-Tool.
ED-Tool is a Windows based setup programme, which provides easy configuration.
Configuration is also possible by using terminal programmes (e.g. HyperTerminal for local
configuration or Telnet for remote configuration). A hardware switch ensures restore of
default settings.
Config mode will be entered; automatically by ED-Tool, manually by terminal programme
or when power is switched on with restore default setting switch set.
First time configure: ED-10 TCP is shipped with IP-address 10.0.0.10.
Please make sure that 10.0.0.10 is compliant to your network, before ED-10 TCP
is connected. Otherwise use serial interface to locally set a valid IP address.
A valid IP address must be compliant with the network in use and not chosen arbitrarily,
ask your network administrator when in doubt.

7.2 Configuration by terminal
ED-10 TCP internal commands must be used to configure by terminal program.
TYPE command
Configuration parameter values can be read by using the 'type' command. E.g. 'type
chip.set↵', will list the chip.set file.
The 'type' command will list configuration parameters and their values, regardless of the
ED-10 TCP operating mode.
The parameters/values are stored in two pairs of configuration files; chip.set,-ini,
factory.set, -ini. See chapter 6.3.
Values used at reboot are stored in the chip.set, -ini files.
Please note, the configuration files also contain parameters that can not be changed.
COPY and REBOOT commands
The 'copy' and 'reboot' commands are used to change ED-10 TCP working mode. The
contents in ED-10 TCP internal file 'autoexec.bat' decides the mode ED-10 TCP will
enter after a reboot.
The 'copy' command is used to copy the ED-10 TCP internal files 'app.bat' or 'config.bat'
to 'autoexec.bat', e.g. 'copy config.bat autoexec.bat↵'.
Reboot is achieved by either the 'reboot' command or by switching the power off and on.
EXIT command
To change configuration parameter values the ED-10 TCP must be in config mode.
When in config mode a value change is requested by a [parameter] [value] pair input,
e.g. 'datarate 19 200↵'.
When all requested changes have been input the 'exit' command must be used to store
the changes into the configuration files. The 'exit' command also copies app.bat to
autoexec.bat ensuring application mode is entered when ED-10 TCP is rebooted.
EXAMPLE 1
Example of how to force the ED-10 TCP into config. mode, change some parameters
and then reboot into application mode with the changed parameters:

Network interface
Port Type (only by switches)
The port type is manually selected, between RS-232 or RS-422/485, by DIP-switches.
The RS-232 port is physically a 9 pin D-sub connector and RS-422/485 is a screw
terminal block.
Port type RS-422/485 uses a transceiver supporting both RS-422 and RS-485.
2- or 4-wire (half or full duplex) is manually selected by DIP-switches.
The transceiver is automatically switched between transmit and receive mode by
incoming network data packets.
Default port type is RS-232.
255.255.255.255
= All IP accepted.
Ignored, not used
The protocol port used
in application mode.

7.3.1. Serial interface
Data Rate
The data rate can be set from 300 bit/s to 115.2 kbit/s.
Default is 19 200 bit/s.
Data Bits
Seven (7) or eight (8) data bits can be selected.
Default is eight data bits.
Parity
No, odd or even parity can be selected.
Default is no parity.
Stop Bits
Two (2) stop bits can be set if no parity is selected.
Default is one (1) stop bit.
Flow Control
Flow control can be chosen between none or hardware. Hardware flow control is managed by the CTS and RTS signal. CTS is switched off (<-3 V) when the ED-10 TCP serial
receive buffer is near full. The buffer size is 10 kB. Serial data from ED-10 TCP will be
transmitted if the RTS is on (>3 V).
Flow control is ignored for port type RS-422/485.
Default, flow control is switched off (none) and the CTS will follow DSR.
Termination and Failsafe (Only by switches)
Termination and fail-safe is used for port type RS-422/485 and can be manually switched
on or off. Switch pair S1:7,8 is used in 2-wire mode. In 4-wire mode switch pairs S1:5,6
are used.
Default is termination and failsafe switched off, i.e. all switch pairs off.
28 6609-2211
7.3.2. Packing algorithm
End of frame character, EoF Char
ASCII code of character indicating end of frame (0-255). The serial data buffered will be
sent over network when this character 0 - 255 is detected (e.g. 13 for Carriage return).
256 will deactivate this function.
Allowed values are 0 – 256.
Default is 256, i.e. deactivated.
End of Frame Delay
The time, after last received character, ED-10 TCP delays until the buffered data frame
is sent over network. Allowed values are 0-2550 ms, 1–9 in 1 ms step and 10–2550 in
10 ms step. The value will be rounded to the nearest lower step (e.g. 128 => 120 ms,
132 =>130 ms).
The value zero (0) deactivates this function, i.e. wait until other criteria is true.
Default value is 20 ms.
If EoF delay is used with low data rates, it should be set to at least one character time.
Note.
Latency has to be added to calculate total delay of data.
Maximum number of bytes/characters in frame
The maximum number of bytes that will be buffered in the data frame. When the data
frame is full the data will be transmitted over network.
Allowed values are 1–1500 bytes. Values above 255 are approximate.
Default is 1000 bytes.
TCP might override this setting.
Transmit end of frame character
Include end of frame character in Network data packet. Allowed alternatives are yes
or no. Default is yes.
296609-2211
7.3.3. Network interface
Local IP address*
Local IP address is used as the first part of local end point identity, in both application
and configuration mode. Do not use Network ID or Broadcast address.
Default is 10.0.0.10.
Local Protocol Port*
The protocol port is the second part of a end point identity. This local TCP port is used
only in application mode. The remote client (computer) must address this local port to
establish a TCP connection.
Allowed values are 1–20, 22, 24–79, 81 - 65535 (>1024 recommended). Port 23 shall
be used for configuration and status information. Port 21 and 80 can not be used.
Please observe that ports 1–1024 are “well-known ports”, hence commonly used by
other programs (e.g. FTP, Telnet, NETBIOS, mail etc). “well-known ports” should
normally not be used by ED-10 TCP. All ”well-known” ports can be found at
http://www.iana.org/assignments/port-numbers
Default is 9000.
Remote IP address*
Required IP address of remote client (computer). The ED-10 TCP will only accept connections (clients) with the Remote IP address. Remote IP address 255.255.255.255 will
force the ED-10 TCP to accept any (all) connections.
An established connection will be closed by a new connection request, if the Remote IP
address is set to 255.255.255.255.
If the Remote IP not are equal to 255.255.255.255 an established connection will remain
established and any new connection requests will be refused.
Default is 255.255.255.255.
Remote Protocol Port
The remote protocol port is not used, hence ignored.
Netmask*
The Netmask is used for Subnet addressing.
Default is 255.255.255.0.
* The IP address must be compliant to the attached network. Ask the network administrator when
in doubt.
30 6609-2211
Gateway IP address*
The Gateway IP address is used for indirect delivery of network packets when the
Remote IP address is not a part of the Network of Local IP address. When the remote
client address is at a different network the packet is sent to the gateway IP address,
which must belong to a router (gateway).
The router will then forward the network packet to its destination (remote client
address). The Local IP address and the Netmask define the network extent.
The Gateway IP address must be on the same net as the local IP, otherwise 0.0.0.0 is
used.
Default is 10.0.0.10.
Telnet user name
User name for remote configuration and status information over network (telnet login).
Default is ed10.
Telnet password
Password for remote configuration and status information over network (telnet login).
Default is ed10.
7.3.4. Mode
The ED-10 TCP can be set into four different modes; Default (0), DTR Control (1), RST
at TCP close (2) and Min. network loading (4).
By default the serial DTR control signal is ignored. But in mode 1 (DTR control) the
ED-10 TCP will await activation of DTR (control signal at CH1: RS-232) before it accept
remote clients and establish a connection. An established connection will further be
closed by de-activation of DTR.
In mode 2 a RST (reset) message is transmitted at the network interface when a connection is closed. By default there is no RST added to the normal close handshaking.
Mode 4 is only recommended for transfer of large amount of continuous data at high
serial data rate. This mode 4 is optimized for maximum throughput and minimum network loading.
By default the ED-10 TCP network performance is optimized for minimum delays.
7.3.5. MAC address
The MAC address of the unit can be found on the product label “00 30 56 F” + last 5
digits on IC2 see figure in section 4.2 Switch settings on page 11. Example: Label on IC2
“SC12 RTOS 0092C2” this will give the unit MAC address “00 30 56 F0 92 C2”
The MAC address can also be find out with the DOS command “ARP –a”.
(Perform the “PING” command with the ED-10 local IP address before the ARP
command.)
* The IP address must be compliant to the attached network. Ask the network administrator when
in doubt.
