2. General Concepts
2.1 Configuration Methods
The Wireless Bridge supports four main methods for setting and configuring the module:
1. Smart mode
Use the buttons and LED’s on the Wireless Bridge to automatically set up the most common use
cases.
2. Web interface
An online web interface with the most common settings for the Wireless Bridge.
3. AT commands
Connect to the Wireless Bridge over Ethernet using TCP, or directly on Layer 2 and use a terminal such as Hyperterminal to issue AT commands. This method is mainly for more advanced settings and use cases, and is not described in this document. All commands available in the web
interface and much more are supported throught the use of AT commands.
4. The SNMP protocol
This will not be used or described in this document.
2.2 Using SMART Configuration Mode
If the Mode button is pressed within 5 seconds from power up, the Wireless Bridge will enter SMART
configuration mode. The LED’s above the button (A, B, C, and D) will show the mode currently selected. When the required mode is selected, it must be confirmed by holding in the Mode button for two
seconds. This will cause the LED’s to start flashing during the operation of the selected mode.
General Concepts 6
Doc.Id. HMSI-27-205
Anybus Wireless Bridge - Ethernet to WLAN
Doc.Rev. 1.20
There are currently 12 different modes available:
"Enable DHCP server" can be used to easily access the Wireless Bridge if the PC is using DHCP, without having to change the PC’s IP settings. This mode should only be used when the PC is connected
directly to the module, and not if the module is connected to a network using a DHCP server. Enable
this mode, then connect the Ethernet cable to the computer. The DHCP server will stay enabled until
a reboot.
How to use the other different modes for specific use cases is described later in this document.
2.2.1 Using the Web Configuration Interface
By default, the Wireless Bridge has the following static IP settings;
• IP address: 192.168.0.99
• Subnet mask: 255.255.0.0
• Default gateway: 192.168.0.99.
To access the module using the web-based configuration interface, the computer must be set up in the
same network, e.g. IP address: 192.168.0.1 and subnet mask: 255.255.0.0.
Open a web browser and enter http://192.168.0.99 in the address field. From here, the most common
configuration parameters needed to set up a connection can be found.

ration to factory defaults.

2.2.2 Reset to Factory Defaults
It is possible to reset to the factory default settings in 4 different ways:
• Enter and confirm SMART mode 2.
• Issue AT&F.
•Hold the Mode button while the Wireless Bridge is starting. Note: Ensure that the Ethernet cable is disconnected, and that any firmware update program has been stopped.
• Press the Restore Device button in the AT-commands section.
2.2.3 Wireless LAN Modes
A Wireless LAN network can be set up in two main connection modes:
• Ad-hoc mode
This is typically used when two WLAN devices connect to each other without going via a WLAN
Access Point. In ad-hoc mode, only 802.11b transmission speeds are used, i.e. a maximum of 11
Mbit/s. The only encryption method supported is WEP.
• Managed (or Infrastructure) mode
This is typically used when a group of devices are connected through a common WLAN Access
Point. In this mode, all available transmission speeds can be used, up to a maximum of
54 Mbit/s. This also allows for user selection of encryption and authentication methods to use.
This means that use cases supporting Managed mode normally have higher throughput.
2.2.4 Wireless Bridge Modes
There are three main Wireless Bridge modes supported by the Wireless Bridge, and these are referred to
in all the use cases described later in this document.
1. Ethernet Bridge mode
In this mode, which is supported only between two Wireless Bridges, the Ethernet packages are
encapsulated in UDP packages and transferred transparently between the two modules. Devices
on both sides of the wireless link are completely unaware of the wireless connection.
2. Client mode
In this mode the Wireless Bridge acts as a wireless extension of the wired Ethernet device it is
connected to. The module is configured to take over (clone!) the MAC address of the connected
device. This means that only ONE Ethernet device can be connected to each module, and not
an Ethernet network with several devices connected through an Ethernet switch or hub. In
"Client Mode", the Wireless Bridge cannot be accessed over the Wireless LAN interface. However, if the Ethernet link is lost, the module will temporarily enter "Multiclient mode" and can
then be accessed again. When the Ethernet link is re-established, the module will revert to "Client
Mode".
3. Multiclient mode
In this mode, the Wireless Bridge acts as in Client mode, but with the addition that multiple devices using the IP layer can be connected.
Ethernet Bridge mode will introduce an extra overhead (because of the encapsulation) and will have a
significantly lower throughput than Client/Multiclient mode.
