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.

Installation Instructions
Installation Instructions
Please also refer to chapter Foreword.
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.

Installation Instructions
Mounting / Unmounting
The CU8890 can be snapped onto a 35 mm mounting rail conforms to
EN 50022.
Mounting the WLANController
Just push the unit on the upper side under the rail (figure 1) and snap in
the lower side as shown below (figure 2):
Unmounting the WLANController
To release the CU8890 from the mounting rail pull down the locking clip
with a screwdriver (figure 1) and pull off the device from the rail (figure 2):

Installation Instructions
Connecting devices
The power supply plug must be withdrawn
Attention
The connections are documented in the section Product Description.
The power supply is realized by the USB connector.
Please read the documentation for the external devices prior to connecting
them.
During thunderstorms, plug connector must neither be inserted nor
removed.
When disconnecting a plug connector, always handle it at the plug. Do not
pull the cable!
Connecting cables
When connecting the cables to the CU8880, proceed according to the
following sequence:
• Switch off all the devices that are to be connected.
• Disconnect all the devices that are to be connected from the power
supply.
• Connect all the cables between the CU8880 and to the devices
that are to be connected.
• Reconnect all devices to the power supply.

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:
