FCC Compliance Statement – Class B

This equipment has been tested and found to comply with the limits for a Class B digital device pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if no installed and used in accordance with the manufacturer’s instruction manual, may cause interference with radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, you are encouraged to try to correct the interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and the receiver.

• Connect the equipment into an outlet on a circuit different from that which

the receiver is connected.

• Consult the dealer or an experienced radio/television technician for help.

Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.

IC Compliance Statement – Class B

This Class B digital apparatus meets the requirements of the Canadian Interference-Causing Equipment Regulations of ICES-003.

Welcome

This document describes how to install and use Echelon’s U10 and U20 USB Network Interface products. The U10 and U20 USB Network Interfaces are lowcost, high-performance LONWORKS interfaces for USB-enabled PCs and controllers. The U10 USB Network Interface connects directly to TP/FT-10 Free Topology Twisted Pair (ANSI/CEA-709.3) L quality removable connector, and is fully compatible with link powered channels. The U20 USB Network Interface connects to PL-20 C-Band Power Line (ANSI/CEA-709.2) L circuit/power supply (either 120VAC with US plug, or 230VAC with Continental Europe plug). The U20 USB Network 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 customersupplied coupling circuit/power supply.

The USB Network Interfaces are certified USB 2.0 compliant by the USB Implementers Forum, work with USB 1.1 certified controllers, and work with USB and Hi-Speed USB systems, peripherals and cables. The drivers are

available on an included CD-ROM, as well as on Microsoft and are accepted into Microsoft's Designed for Windows XP logo testing program. The interfaces also carry the CE, UL, cUL and TÜV agency listings.

Introduction

This chapter introduces the USB Network Interfaces, and describes how to install the software included with the USB Network Interfaces.

LONWORKS USB Network Interface User’s Guide 1

Overview

The USB Network Interfaces are low-cost, high-performance LONWORKS network interfaces for USB-enabled PCs and controllers. Designed for use in L 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.

U10 USB Network Interface

The U10 USB Network Interface (U10 interface) connects to TP/FT-10 (ANSI/CEA-709.3) Free Topology L detachable, quality network connector (included). The U10 interface is fully compatible with TP/FT-10 channels with or without link power.

Figure 1.1 shows the U10 interface. The network connector is on the right side of Figure 1.1, and the USB Series “A” plug is on the left side.

U20 USB Network Interface

The U20 USB Network Interface (U20 interface) connects to PL-20 C-Band Power Line (ANSI/CEA-709.2) L 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 customersupplied coupling circuit/power supply, as described in Appendix A, Alternate Power Line Coupling Circuit.

USB Network Interface LEDs

Each USB interface has three LEDs that you can use to determine the interface’s current state. These LEDs become operational as soon as power is applied to the interface’s USB Series “A” plug.

SVC LED

When the USB interface is not configured, the SVC LED (Service LED) will blink on and off continuously, with a 2 second period and 50% duty cycle. After an application opens and configures the interface, the SVC LED will turn off.

In addition, the SVC LED will illuminate for several seconds after you wink the USB interface from the L wink command allows you to differentiate one interface from another if you have more than one USB interface attached to your PC. The L application and the wink command are described in Chapter 2 of this document.

TX LED

The TX LED (Transmit LED) illuminates when a message is sent through the USB interface to the network. The LED will illuminate for at least 40ms at a time. On TP/FT-10 channels, multiple messages can be transmitted with less than 40ms between them. As a result, the TX LED may be illuminated for extended periods of time on the U10 interface due to the transmission of multiple closely-spaced messages.

RX LED

The RX LED (Receive LED) illuminates when the USB interface receives a message from the network. This LED will illuminate for at least 40ms at a time. On TP/FT-10 channels, multiple messages can be received with less than 40ms between them. As a result, the RX LED may be illuminated for extended periods of time on the U10 interface due to the receipt of multiple closely-spaced messages.
