Description

The PCLTA-21 Network Adapter is a high-performance LonWorks interface for personal

computers equipped with a 3.3V or 5V 32-bit Peripheral Component Interconnect (PCI)

interface and a compatible operating system. Designed for use in LonWorks control

networks that require a PC for monitoring,

managing, or diagnosing the network, the PCLTA-21 adapter is ideal for industrial control,

building automation, and process control applications. The PCLTA-21 adapter features an

integral twisted pair transceiver, downloadable memory, a network management interface,

and plug-and-play capability with Microsoft Windows 98/2000 and Windows XP.

Models 74501R, 74502R, 74503R, and 74504R 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 PCLTA-21 adapter provides both LNS network services interface (NSI) functionality

for use with LNS tools, and Microprocessor Interface Program (MIP)-compatible network

interface functionality for use with LonManager® API-based tools or OpenLDV drivers.

Installation software is included with each PCLTA-21 adapter or may be downloaded from

the Download Center of the Echelon web site. The software includes a control panel and

driver for Microsoft Windows 98/2000 and Windows XP. The control panel provides a

convenient means of setting and modifying installation parameters, diagnosing card

operation, and displaying error messages. The adapter supports plug-and-play operation,

simplifying installation.

The NSI mode of the PCLTA-21 adapter is used with applications based on the LNS

network operating system such as the LonMaker Tool, or the LNS DDE Server.
