WLAN Controller
The CU8890 WLAN controller is an industrial grade data exchange unit for
radio technology. The CU8890 is based on the standard IEEE 802.11 b/g
and is designed for control cabinet installation. Connected to a Beckhoff
Industrial PC the CU8890 can be used either as access-point or as client.
Client drivers are available for Windows XP, XP Embedded as well as
Windows CE, thus for each Beckhoff IPC as well as the CX-series. These
support also adhoc modus.
With the drivers for Windows XP and XP Embedded, the CU8890 can also
operate as an access-point.
The encryption methods are possible from AES-128 bit up to WPA2, the
module is compatible to Cisco CCX and supports PEAP and LEAP. The
data rate is adapted dynamically up to 54 Mbit/s.
The CU8890 has a reverse SMA plug for connection of various radio
antennas. The free choice of antenna enables adaptation to the respective
environment. Beckhoff offers a complete accessories program of antennas
and cables.
The outdoor range between two modules depends on the environment and
can be up to 300 m.
It is possible to choice between 11 channels in the 2.4 GHz-band while
following the country specific rules. The status and the data transfer are
indicated by LEDs, so providing quick and simply diagnostic.
Other outstanding features are:
• user-friendly installation via integrated top hat rail adapter
• power supply via USB - no supply voltage necessary
• IEEE 802.11 b/g and TCP/ UDP IP standard
• maximum 54 Mbit/s data range
• compact industrial design
• clear quick diagnosis by separate LEDs.

Transport and Unpacking
The specified storage conditions must be observed (see chapter Technical
data).
Transport
Despite the robust design of the unit, the components are sensitive to
strong vibrations and impacts. During transport, the unit should therefore
be protected from excessive mechanical stress. Therefore, please use the
original packaging.
Danger of damage to the unit
Attention
If the device is transported in cold weather or is exposed to extreme
variations in temperature, make sure that moisture (condensation) does not
form on or inside the device.
Prior to operation, the unit must be allowed to slowly adjust to room
temperature. Should condensation occur, a delay time of approximately 12
hours must be allowed before the unit is switched on.
Unpacking
Proceed as follows to unpack the unit:
1. Remove packaging.
2. Do not discard the original packaging. Keep it for future relocation.
3. Check the delivery for completeness by comparing it with your order.
4. Please keep the associated paperwork. It contains important
information for handling the unit.
5. Check the contents for visible shipping damage.
6. If you notice any shipping damage or inconsistencies between the
contents and your order, you should notify Beckhoff Service.

Operating Instructions
Operating Instructions
Wireless LANs (WLANs) are local radio networks with main reference to
Channel overlapping
When using the network in a confined area (e.g. in a factory building)
IEEE 802.11 Standard
wireless computer networks. The IEEE 802.11 standard was first published
in 1997.
Basically the standard allows either the wireless connection of two (or
more) PCs (or laptops) with each other directly (adhoc) or to expand an
existing wired computer network with an infrastructure (access points) for
wireless users.
The most popular standard is the IEEE 802.11 b/g that provides a data
transfer rate up to 54 MBit/s for the 2.4 GHz band. The data rate is
adjusted dynamically.
The standard provides 11 channels worldwide, but only 3 can be used
without overlapping:

channels to each neighbor cell:

Placement of the antennas
There must be no obstructions in the direct vicinity of the antenna that
could hinder the development of the Fresnel zone. Metal obstacles such as
control cabinets, machine parts, pipelines, iron beams etc. particularly
hinder the development of the Fresnel zone!
The connection of the antennas to the CU8890 via the RSMA plug and
coaxial cable enables the antenna to be mounted remotely, so that you can
position the antenna optimally.

Operating Instructions
Attenuation and range
Fresnel Zone
Fresnel Zone In radio transmission, the space between the transmitting and receiving
antennas is known as the Fresnel zone. The Fresnel zone is a notional
spheroid between the antennas.
The main portion of the energy is transmitted in the area of the Fresnel
zone.
This zone should be free of obstructions (e.g. objects, houses, trees etc.).
Metal obstacles such as control cabinets, machine parts, pipelines, iron
beams etc. particularly hinder the development of the Fresnel zone!
Each hindrance of the Fresnel zone attenuates the transmission. If the
Fresnel zone is half obscured, for example, the additional attenuation is 6
dB, i.e. the field strength is reduced to half of the free field value. Reception
may then be disturbed or completely interrupted under certain
circumstances.
If the Fresnel zone is free from obstructions, the propagating wave is only
attenuated by the free field attenuation.
Radius r of the Fresnel zone in relationship to the distance s.
Attenuation in practice
Attenuation With an attenuation of 6 dB the range is shortened to half of the value for
an unobstructed connection, with 12 dB it is shortened to a quarter.
Material Attenuation Range approx.

Assembly dimensions
The product is characterized by small overall installed size. With a height of
approx. 100 mm, the module dimensions exactly match those of the
Beckhoff Bus Terminals. Together with the lowered connector surfaces,
this means that it can be used in a standard terminal box with a height of
120 mm.

Calculating with decibels
In communication technology power is expressed in decibels (dB), a tenth
of the unit Bel. It is the logarithmic ratio between two quantities with the
same unit.
A reference variable (P1), e.g. a milliwatt (mW) is compared with the
measured variable (P2). The logarithmic correlation was discovered by
Alexander Graham Bell, in whose honor the unit Bel was named.
Since the number values would be too unwieldy if the Bel was used, it was
agreed to use 1/10 of the value, i.e. the decibel.
Definition of the level difference: Level difference [dB] = 10 log ([P1] / [P2]).
Definition of a power ratio: power ratio = 10
level difference/10
The advantage of expressing the powers and losses (attenuations) in dB is
that the calculation method for power ratios can be replaced by a lower
alculation method for the dB calculation. c

2 x 2 x 2 = 8 3 + 3 + 3 = 9
2 x 100 = 200 3 + 20 = 23
