Important user information

This manual explains how to install, operate and configure a CAN-ETH. This device may

only be used for the applications described in this document.

These instructions are intended for use by trained specialists in electrical installation

and control and automation engineering, who are familiar with the applicable national

standards and safety procedures.

Safety Precautions

ELECTRICAL HAZARD

• This equipment must be installed and serviced only by qualified personnel. Such

work should be performed only after reading this entire set of instructions.

• Before performing visual inspections, tests, or maintenance on this equipment,

disconnect all sources of electric power. Assume that all circuits are live until they

have been completely de-energized, tested, and tagged. Pay particular attention

to the design of the power system. Consider all sources of power, including the

possibility of backfeeding.

• Apply appropriate personal protective equipment and follow safe electrical

practices.

• Turn off all power supplying the equipment in which the CAN-ETH is to be

installed before installing, wiring or removing the CAN-ETH.

• Always use a properly rated voltage sensing device to confirm that power is off.

• The successful operation of this equipment depends upon proper handling,

installation, and operation. Neglecting fundamental installation requirements

may lead to personal injury as well as damage to electrical equipment or other

property.

Failure to follow these instructions could result in death or serious injury!

Introduction

UMCANETH-1901 1

Chapter 1.Introduction

The CAN-ETH is a CAN to Ethernet gateway specifically designed to interface CAN

networks with TCP/IP networks. The gateway features a CAN and an Ethernet port and

can be mounted on a DIN rail. It encapsulates CAN messages into UDP packets and

transports them via Ethernet. The gateway can operate in peer-to-peer or broadcast

modes.

Common applications include:

• CAN bus length extensions

• CAN to DSL bridging

• Wireless networking of CAN networks

2UMCANETH-1901

Features

The CAN-ETH gateway provides the following key features:

• UDP encapsulation for CAN messages

• Peer-to-peer mode

• Broadcast mode

• 8 CAN receive filters

• Low configuration overhead, just an IP address and CAN bitrate to set-up

• Embedded web server for easy configuration and commissioning using a web browser

• Firmware upgradeable via Ethernet

• Status LEDs for power, Ethernet link, device status and communication status

• DIN rail mountable

• 24 V DC (10-30 V) power supply

Quick start checklist

• Read this set of instructions properly and in its entirety.

• Mount the unit.

• Connect the power. Do not connect yet CAN bus or serial ports.

• Configure the Ethernet communications settings with a web browser (using an

Ethernet crossover cable) or with a terminal program like HyperTerminal (using a null

modem cable)

• Configure the CAN bus settings.

• Configure the serial line communication settings.

• Configure the operational aspects of the device.

• Wire CAN bus.

• Wire serial line interfaces.

Chapter 2.Description

The power and CAN terminals are placed on the top side of the unit. The RS-232 and

Ethernet connectors are placed on the bottom side of the unit as shown in the following

LED indicators

Four LEDs located at the front panel indicate the status of the CAN-ETH. The LEDs assist

maintenance personnel in quickly identifying wiring or communication errors.

A LED test is exercised at power-up, cycling each LED off, green and then red for

approximately 0.25 seconds. At the same time the power-on self test of the device is

performed.

4UMCANETH-1901

The following table outlines the indicator condition and the corresponding status after

the power-on self-test has been completed:

LED Function Condition Indication

Power Power Off No power applied to the device.

Green Power supply OK

Link Ethernet link Off No Ethernet link

Green Ethernet link OK

Status1 Device status Off The device has an unrecoverable fault; may need replacing.

Flashing green at 1 s

rate

Device operational but needs commissioning due to configuration

missing, incomplete or incorrect.

Green The device is operating in normal condition.

Flashing red at 1 s rate Device operational but has a fault listed which requires acknowledg-

ment.

Red The device has an unrecoverable fault; may need replacing. Flashing

sequence and rate of Status2 LED indicates fault class.
