USB-Extender-Rx
The USB specification allows a distance of 5 m between the PC and the
USB devices. A further 5 metres of cable can be added by using a USB
hub. In the construction of machines and plants, larger distances must be
bridged without having to insert a USB hub every 5 metres. The CU8800
USB Extender sends the USB signal via a CAT5 cable that can be up to
50 m long to the CU8850 USB Extended receiver, which converts the
signal back to USB. Data rates of up to 12 Mbit/s can be transmitted. Both
USB Extender boxes are designed for DIN rail mounting.
Other outstanding features are:
• user-friendly installation via integrated top hat rail adapter
• 24 V
• 12 Mbit, and 1.5 Mbit support for compatibility to all USB1.1
standards
• standard CAT5 network cable for extension
• compact industrial design
• clear quick diagnosis by separate LEDs for power supply in and
out

Product Description
Power supply
Additional 24 VDC power supply Normally the USB-Extender-Rx CU8850 is
powered via the USB-extension. The device
can also be powered by an additional power
supply (X10).
If a USB device needs more than the specified
max. of 300mA, the additional power supply
must be connected.
The pins have to be connected as shown on
the front panel of the CU8850-device.
Power Supply
UL requirements
For the compliance of the UL requirements the USB-Extender-Rx
should only be supplied
• by a 24 V
protected by means of a fuse (in accordance with UL248), rated
maximum 4 Amp.
supply voltage, supplied by an isolating source and
DC
• by a 24 V
power source, that has to satisfy NEC class 2.
DC
A class 2 power supply shall not be connected in series or
parallel with another (class 2) power source!
To meet the UL requirements, the USB hub CU8800-0000 must not be
Danger
connected to unlimited power sources!
Data Connectors
The CU8850 has two kinds of connectors: RJ45 and USB type A. The
pin layouts are described below.

Installation Instructions
Installation Instructions
Please also refer to chapter General instructions.
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!
Warning
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
Connecting devices
Warning
The connectors are documented in the section Product Description.
The power supply plug must be withdrawn!
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 CU8850 USB-Extender-RX, 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 CU8850 and to the devices
that are to be connected.
• Reconnect all devices to the power supply.
Check voltage rating and connect
1. Check that the external power supply is providing the correct
voltage.
2. Connect the unit to your external 24 VDC power supply.

Architecture Description
Within the USB-Extender-TX (CU8800) and USB-Extender-RX (CU8850)
the length of USB data transmission can be increased from 35 meters
(1 host, 5 USB hubs and a device each connected with 5 meters of cable)
up to 61 meters. Due to the USB signal runtime, it is not possible to
connect more than one USB hub in the chain.
Configuration
The USB hub has to be connected after the CU8850-Box.
The maximal distance is 61 meters: 1 meter of cable from USB host to the
USB extension box CU8800; up to 50 meters extension cable; 5 meters
from extension box CU8850 to the USB hub and 5 meters of cable to the
USB device.

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.
