1. Introduction
The ED-10 is an Industrial Ethernet Adapter with a serial interface. The type of serial
interface is selectable between RS-232 and RS-422/485. The Ethernet interface is
10BaseT and TCP/IP Internet Protocols are used for network communication.
Two ED-10 units can be used to provide a serial point to point link over a TCP/IP network. Each ED-10 passes data from its serial interface to the other unit's serial interface.
This enables long distance serial connections over pre-existing networks.
It is also possible to communicate one to many (e.g. master/slaves), by using a broad-
cast address.
If the customer writes it’s own PC application software, the network interface of ED-10
can be directly accesed.
A software example can be downloaded from the Westermo web site
(www.westermo.se). This example demonstrates how a PC sends network data directly
to the ED-10. Source code, in C, is included.

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 interfaces and transient protection.
The ED-10 is approved for Industrial EMC Immunity (EN50082-2) and EMC Emission
(EN50081-1). All relevant requirements of the Low Voltage Directive are fulfilled.
The ED-10 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 uses TCP for remote configuration (configuration mode) and UDP for
transmitting the serial data over network, i.e. UDP is used in application mode.
UDP uses packet delivery of data, meanwhile TCP uses stream transport.
The ED-10 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.
2. Safety
Serial interface CH1 is not isolated from CH2. They must only be connected to SELV
circuits.
The Network interface must only be connected to TNV or SELV circuits.
See EN 60950:1996 for definitions.
Sound installation practice, as defined by applicable local codes or regulations, shall be
followed in every instance in which such practice is applicable.
