Product Description5 (30)
2Product Description
Anybus Wireless Bolt provides wireless communication over WLAN and/or Bluetooth®to wired
networks.
Typical applications for Anybus Wireless Bolt 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 implementations 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 environments 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.
3.1General Information
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.
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.

3.4Cabling
To make an Ethernet connector cable for the Anybus Wireless Bolt:
Fig. 3Ethernet cable
1.Cut off one of the connectors on a standard Cat5e or Cat6 Ethernet cable.
2.Strip off about 40 mm (1½ inch) of the cable jacket and untwist the orange, orange/white,
green and green/white wires. The other wires will not be used.
3.Strip off about 7 mm (¼ inch) of the isolation on each wire.
4.Push the pin spring release next to each socket on the connector and insert the correct wire
end according to Connector, p. 8.
Connect the wires from the power supply in the same way as the Ethernet wiring. Make sure
that polarity is not reversed.

4.1General
Anybus Wireless Bolt should normally be configured via the web interface. Parameters can be
set individually 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. See AT Commands, p. 20.
The web interface is accessed by pointing a web browser to the IP address of the Wireless Bolt.
The default address is 192.168.0.99.
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.

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 restart and connect to the access point.

•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

Internal DHCP ServerDisabled: 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

Appendix A: Wireless Technology Basics27 (30)
AWireless Technology Basics
Wireless technology is based on the propagation and reception of electromagnetic waves.
These waves respond in different ways in terms of propagation, dispersion, diffraction and reflection depending on their frequency and the medium in which they are travelling.
To enable communication there should optimally be an unobstructed line of sight between the
antennas of the devices. However, the so called Fresnel Zones should also be kept clear from
obstacles, as radio waves reflected from objects within these zones may reach the receiver out
of phase, reducing the strength of the original signal (also known as phase cancelling).
Fresnel zones can be thought of as ellipsoid three-dimensional shapes between two wireless
devices. The size and shape of the zones depend on the distance between the devices and on
the signal wave length. As a rule of thumb, at least 60 % of the first (innermost) Fresnel zone
must be free of obstacles to maintain good reception.
Fig. 22Fresnel zones
Area to keep clear of obstacles (first Fresnel zone)
Distance (d)
100 m1.7 m1.2 m
200 m2.5 m1.7 m
300 m3.0 m2.1 m
400 m3.5 m2.4 m
2.4 GHz (WLAN or Bluetooth)5 GHz (WLAN)
Fresnel zone radius (r)
The wireless signal may be adequate even if there are obstacles within the Fresnel zones, as it
always depends on the number and size of the obstacles and where they are located. This is
especially true indoors, where reflections on metal objects may actually help the propagation of
radio waves. To reduce interference and phase cancelling, the range may also need to be limited by reducing the transmission power. For determining the optimal configuration and placement of wireless devices it is therefore recommended to use a wireless signal analysis tool.
