Product Description 5 (32)
2 Product Description
Anybus Wireless Bridge II provides wireless communication over WLAN and/or Bluetooth®to
wired networks.
Typical applications for Anybus Wireless Bridge II include:
• Adding wireless cloud connectivity to industrial devices
• Accessing devices from a laptop, smartphone or tablet
• Ethernet cable replacement between devices
Limitations:
Bluetooth PAN (Personal Area Network) may not work with some devices due to different imple-
mentations of Bluetooth by different manufacturers.
WLAN 5 GHz cannot be used at the same time as WLAN 2.4 GHz or Bluetooth.
WLAN or Bluetooth?
Choose WLAN when data throughput and seamless roaming are most important and there are
few other radio emitting devices in the environment.
Choose Bluetooth if connection robustness and low latency are most important, and in environ-
ments with many other radio emitters.

Caution
This equipment emits RF energy in the ISM (Industrial, Scientific, Medical) band.
Make sure that all medical devices used in proximity to this device meet
appropriate susceptibility specifications for this type of RF energy.
This product is recommended for use in both industrial and domestic environments.
For industrial environments it is mandatory to use the functional earth connection
to comply with immunity requirements. For domestic environments the functional
earth must be omitted if a shielded Ethernet cable is used, in order to meet
emission requirements.
This product contains parts that can be damaged by electrostatic discharge (ESD).
Use ESD protective measures to avoid equipment damage.
3.1 General
Make sure that you have all the necessary information about the capabilities and restrictions of
your local network environment before installation.
The characteristics of the internal antenna should be considered when choosing the placement
and orientation of the unit (unless an external antenna is used).
See Technical Data, p. 28 for details about the antenna characteristics.
For optimal reception, wireless devices require a zone between them clear of objects that could
otherwise obstruct or reflect the signal. A minimum distance of 50 cm between the devices
should also be observed to avoid interference.
See also Wireless Technology Basics, p. 27.

Configuration 10 (32)
4 Configuration
4.1 General
Anybus Wireless Bridge II should normally be configured via the web interface or using one of
the pre-configured Easy Config modes.
Advanced configuration can be carried out by issuing AT (modem) commands through the web
interface or over a Telnet or RAW TCP connection to port 8080. The Help page in the web inter-
face includes a list of all supported AT commands.
The web interface is accessed by pointing a web browser to the IP address of the Wireless
Bridge. The default IP address is 192.168.0.99. The computer accessing the web interface must
be in the same IP subnet as the Wireless Bridge.
The web interface is designed for the current stable versions of Internet Explorer,
Chrome, Firefox and Safari. Other browsers may not support the full functionality
of the web interface.

Configuration 11 (32)
4.2 Easy Config
1. Power on the unit and wait for the Link Quality LEDs to light up and go out again, then
press and release the MODE button.
Step 1 must be carried out within 5 seconds of startup.
2. Press MODE repeatedly to cycle through the Easy Config modes until the desired mode is
indicated by the A-B-C-D LEDs.
Mode 2 is the first mode, which means that the number of required button presses are al-
ways one less than the mode number.
3. Press and hold MODE for 2 seconds, then release the button. This will confirm the selected
mode and restart the unit.
Step 3 must be carried out within 20 seconds of step 2, otherwise the unit will exit Easy
Config setup and return to the previous settings.
4.2.1 Easy Config Modes
Mode Role Description A B C D
2—Reset configuration to factory defaults
3—Reset IP settings to factory defaults
4 Client Wait for discovery and configuration
5 WLAN AP
Discover units in Mode 4 and configure them as clients
6 Bluetooth
NAP
Modes 4, 5 and 6 are used in combination to automatically set up a WLAN or Bluetooth network
with units of this type.
Modes 5 and 6 will scan for units in Mode 4. Each detected unit in Mode 4 will be reconfigured
as a client, and the scanning unit will be configured as an access point. The clients will then re-
start and connect to the access point.
Mode Timeout
• Mode 5 and 6 will scan for 120 seconds. The mode can be activated repeatedly to scan for
additional units.
• Mode 4 will listen for 120 seconds, or until it has received a valid configuration from a unit
scanning in Mode 5 or 6.
The IP address of a client may be changed by the configuration from the access
point. Active browser sessions could therefore be lost.

4.3.3 Network Settings
Fig. 7 Network Settings page
IP Assignment Select static or dynamic IP addressing (DHCP)
IP Address Static IP address for the unit
Subnet Mask Subnet mask when using static IP
Default Gateway Default gateway when using static IP
Internal DHCP Server Disabled: No internal DHCP functionality
DHCP Relay Enabled: The unit can receive a DHCP request on one interface
and resend it to a DHCP server located on one of the other interfaces. Only a
single DHCP server can be active for all the connected interfaces.
DHCP Server Enabled: Activates an internal DHCP server. This option is only
available if IP Assignment is set to static.
The internal DHCP server will assign up to 7 consecutive IP addresses in the
subnet specified by the netmask, starting from x.x.x.1. If the unit itself is located
within the DCHP range, its IP address will be skipped and the next IP address will
be assigned instead. The last assigned IP address will then be x.x.x.8.
Example 1: (Netmask 255.255.255.0)
Device IP address: 192.168.0.99
DHCP Server addresses: 192.168.0.1 - 192.168.0.7
Example 2: (Netmask 255.255.255.0)
Device IP address: 192.168.0.3
DHCP Server addresses: 192.168.0.1 - 192.168.0.8 (excluding 192.168.0.3)
Example 3: (Netmask 255.255.0.0)
Device IP address: 192.168.5.5
DHCP Server addresses: 192.168.0.1 - 192.168.0.7
Do not enable this option if there is already a DHCP server on the network!
If the static IP address is changed the browser should automatically be redirected to the new
address after clicking on Save and Reboot.
The automatic redirect function may not be supported by all browsers.
