Product Overview

View of the CU8880-0000

The CU8880 USB-to-LAN adapter places an additional industrially-suited

and independent Ethernet interface at the user’s disposal. In this way, four
or more Ethernet interfaces can be implemented, depending on the system
configuration. The CU8880 is used for necessary IT communication, so
that the respective on-board Ethernet interfaces are available for EtherCAT
or real-time Ethernet communication. Drivers for the USB-to-LAN adapter
are available for Windows XP Professional, and Windows XP Embedded.

• user-friendly installation via integrated top hat rail adapter

power supply via USB - no supply voltage necessary

•

• compact industrial design

• clear quick diagnosis by separate LEDs.

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 u se 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.

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.
