U10/U20 USB
Network Interface
Low-cost and
rugged design
Low Cost, High Performance USB
interface for PCs provides an effective
interface for a Free Topology twisted
pair LONWORKS
®
channel.
Certied
USB 2.0 compatible by the USB
Implementers Forum. In addition, the U10 and U20
interfaces carry the Designed for Windows XP logo
compatibility certication.
• Low-cost USB to LonWorks
(ANSI/CEA-709.1) network interface.
• Free topology twisted pair
(TP/FT-10) and power line (PL-20
C-Band) LonWorks channel support.
• Highest possible network throughput
and performance.
• Rugged design, removable connectors.
• Plug-and-play drivers for Windows XP,
2000, and Server 2003.
• Functions as an LNS® High Perfor-
mance Network Interface when used
with LNS 3 and LNS Turbo Edition.
• Compatible with OpenLDV™
applications and the LonScanner™
Protocol Analyzer.
• CE, UL, cUL, and TÜV.
The U10 and U20 USB Network
Interfaces are low-cost, high-performance
LonWorks interfaces for USB-enabled PCs.
The U10 USB Network Interface connects
to a TP/FT-10 Free Topology Twisted Pair
(ANSI/CEA-709.3) LonWorks channel
through a removable connector, and is fully
compatible with link powered channels.
The U20 USB Network Interface connects
to a PL-20 Power Line (ANSI/CEA-709.2)
LonWorks channel through a wall plug
coupling circuit/power supply (included).
The U20 interface may also be connected
directly to 10.8-18VDC power lines without
a coupling circuit, or to virtually any
powered line with a customer-supplied
coupling circuit/power supply.
The U10 and U20 interfaces are ideal for
industrial control, building automation,
process control, home automation, and
transportation applications. The interfaces
feature easy-to-install, auto-conguring
drivers for Microsoft Windows XP, 2000,
and Server 2003, and are compatible
with LNS 3 and Turbo Edition applications,
including the LonMaker® Integration Tool.
When used with LNS 3 or LNS Turbo
Edition, the U10 and U20 interfaces
function as LNS High Performance
Network Interfaces—you get the highest
possible performance at the lowest cost
in the market. Apart from the superior
performance when used with LNS, the U10
and U20 interfaces are compatible with
OpenLDV based applications, as well as
the LonScanner Protocol Analyzer.
In addition to being certied to quality
standards such as CE, UL and TÜV, models
75010R, and 75021R are compliant with
the European Directive 2002/95/EC on the
restriction of the use of certain hazardous
substances (RoHS) in electrical and
electronic equipment.
The U10 and U20 interfaces are
certied USB 2.0 compatible by the USB
Implementers Forum. In addition, the U10
and U20 interfaces carry the Designed for
Windows XP logo compatibility certication.
A 60cm USB extension cable is included
with both the U10 and U20 interfaces, to
allow for easy connection in various laptop
and desktop environments.
Installation software and a user’s guide are
included on the CD-ROM, and may also be
downloaded from Echelon’s Web site.
