IGW/400-UART – Introduction
SSV EMBEDDED SYSTEMS 3
1 INTRODUCTION
The WLAN Device Server IGW/400-UART 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-UART. 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-UART. UART1 correlates with the
RS232 connector (UART1) and the EI/Os correlate with the 14-pin environment interface
of the IGW/400-UART.

IGW/400-UART – Components
SSV EMBEDDED SYSTEMS 5
3 COMPONENTS
This chapter describes the components of the IGW/400-UART shown in chapter 2 and
gives a short overview about their respective functions.
3.1 14-Pin Environment Interface Connector (EI/O)
The environment interface connector 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-UART needs a supply voltage of 6 - 30 VDC to work.
Furthermore it is possible to create a RS232 (pins 3 - 8) and a RS422 (pins 10 - 13)
connection with the Sub-D adapter cable. Please refer to chapter 5.1 for the complete
pinout.
Caution: Providing the IGW/400-UART with a supply voltage higher than 30 VDC
could damage the IGW/400-UART!
3.2 Power LED
The green power LED indicates a present supply voltage. This LED is on when the
IGW/400-UART 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-UART.
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-UART.
3.4 RS232 Connector (UART1)
The IGW/400-UART 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 null-modem cable.
3.5 Reverse SMA Connector for WLAN Antenna
The reverse SMA connector is used to attach the WLAN antenna to the IGW/400-UART.
3.6 10/100 Mbps Ethernet Interface
The IGW/400-UART allows Ethernet connectivity with a speed up to 100 Mbps. The
LAN interface of the IGW/400-UART 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.
