2 L ON W ORKS USB Network Interface User’s Guide
Overview
The USB Network Interfaces are low-cost, high-performance L ON W ORKS network
interfaces for USB-enabled PCs and controllers. Designed for use in L ON W ORKS
control networks that require a PC for monitoring, managing and diagnosing the
network, the USB Network Interfaces are ideal for industrial control, building
automation, process control and transportation applications. The USB Network
Interfaces feature easy to install, auto-configuring drivers for Microsoft Windows
XP, Windows 2000 and Windows Server 2003, and are compatible with all LNS
and OpenLDV applications, as well as with the LonScanner Protocol Analyzer.

U20 USB Network Interface
The U20 USB Network Interface (U20 interface) connects to PL-20 C-Band
Power Line (ANSI/CEA-709.2) L
ON W ORKS channels through an included plug-in
coupling circuit/power supply. The U20 interface can also be connected directly
to 10.8-18VDC power systems (such as those in automobiles, trucks and buses)
without a coupling circuit, or to virtually any powered line through a customer-
supplied coupling circuit/power supply, as described in Appendix A, Alternate
Power Line Coupling Circuit.
