PCLTA-21 Introduction
This guide describes the mechanical characteristics and the
hardware and software driver installation for the Echelon PCLTA21 Interface (Models 74501, 74502, 74503, 74504, and 74505).
Echelon’s PCLTA-21 card is a high-performance LONWORKS®
interface for desktop and embedded personal computers equipped
with a 3 or 5V 32-bit PCI interface and a compatible operating
system. Designed for use in LONWORKS networks that require a
PC to monitor, manage, or diagnose the network, the PCLTA-21
card is ideal for industrial control, building automation, and
process control applications. The PCLTA-21 card features support
for TP/XF-78, TP/XF-1250, TP/FT-10, and RS-485 transceivers,
downloadable memory, a network management interface, and Plug
n’ Play capability with Microsoft Windows 98, 2000, and XP
operating systems.
The four versions of the PCLTA-21 interface with integral twisted
pair transceivers support the TP/FT-10 (Model 74501), TP/XF-78
(Model 74502), TP/XF-1250 (Model 74503), and TP-RS485 (Model
74504) channels, respectively.
The PCLTA-21 card can be used as an LNS® High Performance
Network Interface, a standard LNS network interface, or a
LonManager API-compatible interface.

Overview
The PCLTA-21 card provides any PC equipped with a 32-bit PCI interface
and compatible Windows operating system access to a L
The PCLTA-21 installation software provides a software-based control
panel and a software driver for Microsoft Windows 98, 2000, or XP
operating system. Installation software also is available on Echelon’s web
site at www.echelon.com/downloads. The control panel provides a
convenient means of setting and modifying installation parameters, as well
as displaying error messages. The adapter supports Windows 98, 2000, and
XP Plug n’ Play operation, simplifying installation and use.
The PCLTA-21 card operates at 10MHz and includes integral twisted pair
transceiver. The network connection is made via a removable screw
terminal block.
Firmware for the PCLTA-21 is downloaded from the host PC. This allows
the card to be updated as new versions of the software and firmware are
released, without modifying or physically accessing the PCLTA-21 card.
This feature extends the useful service life of the card, and minimizes the
cost and time associated with software and firmware updates. The card is
provided with 32Kbytes of off-chip RAM for use as network and application
buffers.

Installing the PCLTA-21 Card

PCLTA-21 Card Software Installation
There are two versions of the PCLTA-21 installation software, one for Windows
2000 and XP and one for Windows 98. Each version installs the files required by
the associated Windows operating system to recognize the PCLTA-21 card, as
well as the downloadable LNS and MIP images.
Windows 2000 and XP Software Installation Procedure
To install the PCLTA-21 software on a Windows 2000 or XP PC, follow the
instructions below. The PCLTA-21 software cannot be installed from DOS or a
DOS shell. The PCLTA-21 software can support DOS applications via the DOS
virtual device driver. The default mode of operation is as an LNS high
performance network interface; the LonManager API-compatible MIP mode
image may be enabled through the driver software control panel.
!
Installation of the PCLTA-21 software MUST precede insertion of a
PCLTA-21 card into a PCI slot.
Failure to install the software before inserting the card will render the card
unusable until the software is removed, and then reinstalled.
1. Close all open programs.
2. Insert the installation CD into the PC.
3. Open the Windows Start menu and select the Run command.
4. When prompted for a program name, enter the following:
E:Win2K-XP\SETUP.EXE (where E: represents your CD ROM)
5. When prompted with a list of languages, click on the desired language. A
checkmark will appear to the left of the language to be installed.
6. When prompted for a destination directory, enter the desired installation
directory. By default this directory is c:\lonworks, unless previous

!
The path may be modified using the Browse button; however, if a directory other
than c:\lonworks is chosen, the PCLTA-21 images path will have to
be specified to enable use of the PCLTA-21 card. This is accomplished
during PCLTA-21 Configuration. See Chapter 3, Configuring and Testing
the PCLTA-21 Adapter.
7. There is a limit of six (6) PCLTA-21 cards in a single PC.
8. The installation software for the Windows 2000 and XP versions will issue a
prompt to add a DOS virtual-mode device driver file to the DOS CONFIG.NT file
(to support DOS applications) called LON1. This will allow DOS applications to
be used in a Windows 2000 or XP DOS shell/window. For more information see
Virtual-Mode DOS Driver later in this chapter. The following line is added to the
CONFIG.NT file:
DEVICE=%SYSTEMROOT%\SYSTEM32\PCLTDOS.SYS /D1
The argument /D1 names this DOS device as LON1.
9. Software installation is complete. At the prompt to restart the computer, remove
the PCLTA-21 installation CD, turn off power, install the PCLTA-21 card, and
then reboot the computer. Windows will recognize the PCLTA-21 and complete
the installation.
Windows 98 Software Installation Procedure
To install the PCLTA-21 software on a Windows 98 PC, follow the instructions below.
The PCLTA-21 software cannot be installed from DOS or a DOS shell.
!
Installation of the PCLTA-21 software MUST precede insertion of a
PCLTA-21 card into a PCI slot.
Failure to install the software before inserting the card will render the card
unusable until the software is removed, and then reinstalled.
1. Close all open programs.
2. Insert the installation CD into the PC.
