IGW/400-CAN – Introduction

SSV EMBEDDED SYSTEMS 3

1 INTRODUCTION

The WLAN Device Server IGW/400-CAN integrates typical measurement and control

interfaces into an IEEE 802.11b/g-compatible WLAN/WiFi Network.

This very compact system acts as small, easy to use interface converter, which collects

any data of industrial automation components and transmits it via IEEE 802.11-based

WLAN.

This document describes the hardware components of the IGW/400-CAN. For further

information about the individual components of this product you may follow the links

from our website at http://www.ssv-comm.de.

Our website contains a lot of technical information, which will be updated in regular

periods.

1.1 Block Diagram

Figure 1 shows the block diagram of the IGW/400-CAN. UART1 of the WLAN Interface

correlates over a level shifter with the Sub-D RS232 connector. UART2 is internally

connected to the Environment Interface. This subsystem is based on an ARM7TDMI

microcontroller with 256 Kbytes flash and 16 Kbytes SRAM memory. The

microcontroller implements the two CAN channels (CAN1, CAN2), one RS232 serial

port (COM1) and two GPIOs with I2C and analog inputs.

3 COMPONENTS

This chapter describes the components of the IGW/400-CAN shown in chapter 2 and

gives a short overview about their respective functions.

3.1 14-Pin Environment Interface

The environment interface is used to connect external devices to the two CAN channels,

the RS232 interface (RxD / TxD only) and to the two GPIOs.

Furthermore the environment interface is used to connect the power supply unit via the

power supply adapter cable to the pins 1 and 2 of the environment interface. The

IGW/400-CAN needs a supply voltage of 6 - 30 VDC to work.

Caution: Providing the IGW/400-CAN with a supply voltage higher than 30 VDC could

damage the IGW/400-CAN!

3.2 Power LED

The green power LED indicates a present supply voltage. This LED is on when the

IGW/400-CAN is provided with a voltage of 6 - 30 VDC by the power supply. If this

LED is off, check the connection between the power supply and the IGW/400-CAN.

Check also if the power supply is set to 6 - 30 VDC. The default setting of the power

supply is 12 VDC.

3.3 WLAN Activity LED

The red WLAN activity LED indicates activity on the WLAN interface. If this LED is

off, check the WLAN connection settings of the IGW/400-CAN.

3.4 RS232 Connector (UART1)

The IGW/400-CAN is equipped with a standard RS232 connector named UART1. This

interface comes with a 9-pin Sub-D male connector. The pin assignment of UART1 is

identical to the COM port assignment of a PC, so it is possible to use a standard cable.

3.5 Reverse SMA Connector for WLAN Antenna

The reverse SMA connector is used to attach the WLAN antenna to the IGW/400-CAN.

3.6 10/100 Mbps Ethernet Interface

The IGW/400-CAN allows Ethernet connectivity with a speed up to 100 Mbps. The LAN

interface of the IGW/400-CAN is a standard RJ45 Ethernet interface. The LAN interface

is an alternative to the WLAN antenna. You cannot use the LAN interface and the

WLAN antenna at the same time.
