2 General Information About Wireless LAN
2.1 INSYS WLAN serial and INSYS WLAN bridge
The INSYS WLAN serial and INSYS WLAN bridge are communication devices for industrial
applications. They are designated for the use on the DIN rail in the switchboard. In the
Wireless LAN, the transmission of data takes place with up to 11 Mbit/s, according to the
industrial standard IEEE 802.11 b.
WLAN connections may be established to AccessPoints (infrastructure mode) as well as
in adhoc networks. The radio connection is made with a main antenna and optionally
with an auxiliary antenna for improved reception (diversity). The antenna connections
are reverse SMA plugs. The radio connection is protected by Wireless Equivalent Privacy
(WEP) with 64 or 128 bit keys.
2.1.1 INSYS WLAN serial
The INSYS WLAN serial transmits the serial data in IP packets, the standard for local
networks and the Internet. At the remote terminal, control software receives the data
directly or via a virtual COM port. The configuration takes place via the configuration
software HSComm, AT commands or Telnet. The serial interface works with up to 115
kbps.
Both devices have 2 digital inputs and 2 galvanic insulated outputs, which may be used
for additional tasks.
2.1.2 INSYS WLAN bridge
The INSYS WLAN bridge is an Ethernet WLAN bridge, which integrates Ethernet devices,
or connects two network segments with each other, by a radiolink.
The configuration takes place via a web interface (Ethernet or WLAN); the Ethernet
access is designed as 10 Base-T. The IP address can be allocated directly or via DHCP.
2.2 Infrastructure or Adhoc Mode
The wireless network according to the standard WLAN IEEE 802.11b enables the
operation in two different modes:
version 1.01 / 10.04
