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

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.
