PCLTA-20 PCI Interface User’s Guide 1-3
Introduction
The PCLTA-20 card provides any PC equipped with a 32-bit PCI interface and
compatible Windows operating system with access to a LONWORKS network.
Installation software for the PCLTA-20 card is included with the Model 33100-20
LONWORKS PCLTA-20 Protocol Analyzer, the Model 37000 LonMaker Integration Tool,
the Model 37200 LNS DDE Server, the Model 34309 LNS Application Developer’s Kit,
and the Model 58030-01 Connectivity Starter Kit (which must be purchased separately).
The software provides a software-based control panel and a software driver for Microsoft
Windows 95, 98, Me, NT, or 2000 operating systems (the PCLTA-20 Protocol Analyzer
requires Windows 95 or 98). Installation software also is available on Echelon’s web site
at www.echelon.com/toolbox. The control panel provides a convenient means of setting
and modifying installation parameters, as well as displaying error messages. The
adapter supports Windows 95, 98, Me, and 2000 Plug n’ Play operation, simplifying
installation and use.
The PCLTA-20 card operates at 10MHz and, depending on the model selected, includes
either an integral twisted pair transceiver or an SMX transceiver interface. For models
with an integral twisted pair transceiver, the network connection is made via a
removable screw terminal block.
As shown in figure 1.1 below, the LNS network operating system allows any number of
installation, maintenance, monitoring, and control devices to exist in a system and to
adapt to network configuration changes automatically. That is, it allows users to
reconfigure the system from any user interface device anywhere on the network and
ensures that all monitoring and control stations are always up-to-date with respect to
the system’s configuration. When used with the appropriate software, the LNS Fast
Network Interface functionality of the PCLTA-20 card allows the attached host to tap
into the LNS infrastructure as a client or server application.
