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. Users can reconfigure the system from any user
interface device anywhere on the network and ensure 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 network services interface (NSI)
functionality of the PCLTA-20 adapter allows the attached host
to run LNS applications.
In both NSI mode and MIP modes, the adapter also permits
the host PC to act as an L

ORKS
application device, run-
ning application-specific programs while the adapter handles
lower layer functions such as media access control, collision
avoidance, message validation, authentication, and priority
processing. The host application, including its network vari-
ables, can be changed at any time without modifying the
adapter. The PCLTA-20 adapter combined with the host PC
can also be used with applications that require more processing
power, memory, input/output capability, or network variable
connections than are provided by the Neuron
®
Chip alone.
Firmware for the adapter is downloaded from the host PC.
This allows the adapter to be updated as new versions of the
software and firmware are released, without modifying or
physically accessing the PCLTA-20 adapter. This feature
extends the useful service life of the adapter, and minimizes the
cost and time associated with software and firmware updates.
Description
Models 74401, 74402, 74403, and 74404 are replaced with
a newer version of PCLTA product line called PCLTA-21 PCI
Network Adapter.
The PCLTA-20 PC LonTalk Adapter is a high-performance
L
ON
W
ORKS
interface for personal computers equipped with a
32-bit Peripheral Component Interconnect (PCI) interface and a
compatible operating system. Designed for use in L
ON
W
ORKS
control networks that require a PC to monitor, manage, or
diagnose the network, the PCLTA-20 adapter is ideal for indus-
trial control, building automation, and process control applica-
tions. The PCLTA-20 adapter features either an integral twisted
pair transceiver or an SMX transceiver interface, downloadable
memory, a network management interface, and plug-and-play
capability with Microsoft Windows 95/98/2000 and Windows
NT.
Model 74405R is 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-20 adapter provides both LNS network ser-
vices interface (NSI) functionality for use with LNS tools, and
Microprocessor Interface Program (MIP)-compatible network
interface functionality for use with LonManager
®
API-based
tools.
Installation software for the PCLTA-20 adapter is provided
with the LonMaker
®
Integration Tool, LNS DDE Server, and
LNS Application Kit software distributions, or may be down-
loaded from the developer’s tool box section of the Echelon
web site. It includes a software-based control panel and a
software driver for Microsoft Windows 95/98/2000/XP/Server
2003 and Windows NT. The control panel provides a conve-
nient means of setting and modifying installation parameters,
diagnosing card operation, and displaying error messages.
The adapter supports plug-and-play operation, simplifying
installation.
