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.

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 application 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 discharging 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 service 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 or TNV-1 circuits.

5.1 Mounting / Removal

Before mounting or removing the unit:

Prevent damage to internal electronics from electrostatic discharges (ESD) by discharging your body to a grounding point (e.g. use of wrist strap).

Prevent access to hazardous voltages by disconnecting the unit from AC/DC mains supply and all other electrical connections.

Mounting

This unit should be mounted on 35 mm DIN-rail which is horizontally mounted on a wall or cabinet backplate.

This unit uses convection cooling. To avoid obstructions to the airflow around the unit,use the following spacing rules. Recommended spacing 25 mm (1.0 inch) above/below and 10 mm (0.4 inches) left/right the unit.

Snap on mounting (figure)

5.2 Connections

CH1 is used for the serial/network conversion. Type of interface (RS-232 or RS-422/485) connected must also be set at DIP switch S1. (Ref. section 4.2)

CH2 is used for local configuration. CH1 and CH2 are not galvanic isolated.

Please use a RS-232 isolator (e.g.Westermo MD-52) if earth voltage differences are suspected. An isolator,on permanently connected CH2, is required to maintain the enhanced transient/surge protection.
