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.
