PCLTA-20 Introduction
This guide describes the mechanical characteristics and the hardware
and software driver installation for the Echelon PCLTA-20 Interface
(Models 74401, 74402, 74403, 74404, and 74405) and the Echelon
PCLTA-20 Protocol Analyzer Card (included with Model 33100-20).
Except where noted, the term “PCLTA-20” used in this guide refers to
both cards.
Echelon’s PCLTA-20 card is a high-performance LON WORKS® interface
for desktop, and embedded personal computers equipped with a 32-bit
PCI interface and a compatible operating system. Designed for use in
LON WORKS networks that require a PC to monitor, manage, or diagnose
the network, the PCLTA-20 card is ideal for industrial control, building
automation, and process control applications. The PCLTA-20 card
features support for a wide range of transceivers, downloadable memory,
a network management interface, and Plug n’ Play capability with
Microsoft® Windows 95, 98, Me, NT, and 2000 operating systems. The
PCLTA-20 protocol analyzer requires Windows 95 or 98.
The four versions of the PCLTA-20 interface with integral twisted pair
transceivers support the TP/FT-10 (Model 74401), TP/XF-78 (Model
74402), TP/XF-1250 (Model 74403), and TP-RS485 (Model 74404)
channels, respectively. The Model 74405 PCLTA-20/SMX interface and
the PCLTA-20 Protocol Analyzer support SMX transceivers, and may
therefore be used on a wide range of channels, including Echelon’s
PCLTA-20 PCI Interface User’s Guide
1-1
TP/FT-10 free topology and PL-10, PL-20, and PL-30 power line
channels.
The PCLTA-20 card can be used as an LNS Fast Network Interface, a
standard LNS network interface, or a LonManager API-compatible
interface.
The L ON WORKS PCLTA-20 Protocol Analyzer provides L ON WORKS
manufacturers, system integrators, and end-users with a rich set of
Windows tools and a PCLTA-20 card for observing, analyzing, and
diagnosing the behavior of L ON WORKS networks. In addition to
providing the network analysis functionality, the PCLTA-20 card
included with the protocol analyzer also provides all the functionality of
the PCLTA-20 PCI Interface.
1-2
Introduction
Introduction
The PCLTA-20 card provides any PC equipped with a 32-bit PCI interface and
compatible Windows operating system with access to a LON WORKS network.
Installation software for the PCLTA-20 card is included with the Model 33100-20
LON WORKS 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.

The card also permits the host PC to act as a LON WORKS network device, running
application-specific programs while the card handles lower layer functions such as
media access control, collision avoidance, and message validation
Firmware for the card 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-20 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-20 Card
This chapter describes the procedures for installing the PCLTA-20 card.
PCLTA-20 PCI Interface User’s Guide
2-1
PCLTA-20 Card Software Installation
There are three versions of the PCLTA-20 installation software, one for Windows
95/98/Me, one for Windows NT, and one for Windows 2000. Each version installs the
files required by the associated Windows operating system to recognize the PCLTA-20
card, as well as the downloadable LNS, protocol analyzer, and MIP images.
PCC-10 Card Software Installation
!
Installation of the PCLTA-20 software must precede insertion of
a PCLTA-20 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.
The installation process is as follows:
1.
If you have purchased the LonManager PCLTA-20 Protocol Analyzer, install
the protocol analyzer applications following the instructions provided in the
LonManager Protocol Analyzer User’s Guide. You cannot use the
LonManager ISA Protocol Analyzer card and a PCLTA-20 card in the same
PC.
2.
If you have purchased a LonMaker Integration Tool, LNS DDE Server, or LNS
Application Development Kit, install the software as described in the
documentation included with the software. Select the option to install the
PCLTA-20 driver. If you do not have one of these products, install the PCLTA20 driver software as described below.
3.
Insert the PCLTA-20 card, as described later in this chapter.
Note: If the LON WORKS Protocol Analyzer software is installed after installing the
PCLTA-20 card software, the PCLTA-20 card software must be re-installed.
The PCLTA-20 software can support DOS applications via the DOS virtual device
driver. The default mode of operation is as an LNS network interface; the LonManager
API-compatible MIP mode image may be enabled through the driver software control
panel.
2-2
Installing the PCLTA-20 Card
Windows 95/98/Me Software Installation Procedure
To install the PCLTA-20 software on a Windows 95/98/Me PC, follow the instructions
below. The PCLTA-20 software cannot be installed from DOS or a DOS shell.
1.
Close all open programs. Do not insert the PCLTA-20 card into a PCI slot at this
time.
2.
Insert the installation diskette into the PC.
3.
Open the Windows Start menu and select the Run command.
4.
When prompted for a program name, enter the following:
a:SETUP.EXE
If necessary, replace a: with the drive letter that corresponds to the drive containing
the PCLTA-20 installation diskette.
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 LON WORKS products
have been installed and registered a different path in the Windows Registry. The
path may be modified using the Browse button; however, if a directory other than
c:\lonworks is chosen, the PCLTA-20 images path will have to be specified to
enable use of the PCLTA-20 card. This is accomplished during PCLTA-20
Configuration. See Chapter 3, Configuring and Testing the PCLTA-20 Adapter.
7.
When the 16-bit Application Support prompt appears, select “Yes” to enable the use
of 16-bit applications with the PCLTA-20 card. This option is required for the
PCLTA-20 Protocol Analyzer, but is not required for the LonMaker Integration Tool,
LNS DDE Server, LNS Application Developer’s Kit, or other LNS applications.
This causes the installation program to add references to the DOS CONFIG.SYS file
for the stub device drivers named PCCLON1 and PCCLON2. This allows existing 16bit applications to recognize these device names and use the PCLTA-20 card as a
network interface. If more than two PCLTA-20 cards are installed in the PC,
additional stub drivers can be created manually. To do so, add the following lines to
the CONFIG.SYS file:
DEVICE=C:\LONWORKS\BIN\LDVSTUB.SYS /D:PCCLON3
DEVICE=C:\LONWORKS\BIN\LDVSTUB.SYS /D:PCCLON4
There is a limit of six (6) PCLTA-20 cards in a single PC.
PCLTA-20 PCI Interface User’s Guide
2-3
8.
If the installation software discovers the SYSTEM.INI entry that loads the
ECHLMPA.386 ISA bus driver, it will comment out the entry and display the
following message, “SETUP has modified your SYSTEM.INI file by removing the
following entry: device=echlmpa.386.” It is not possible to use the ISA-bus protocol
analyzer card and the PCLTA-20 card on the same PC.
9.
The installation software for the Windows 95/98/Me version will issue a prompt to
add a DOS virtual-mode device driver file named LDVVDD.SYS to the DOS
CONFIG.SYS file to support DOS applications calling LON1. This will allow DOS
applications to be used in a Windows 95/98/Me DOS shell/window. For more
information see Virtual-Mode DOS Driver later in this chapter. The following line
is added to the CONFIG.SYS file:
DEVICE=C:\LONWORKS\BIN\LDVVDD.SYS /D1
10. Software installation is complete. At the prompt to restart the computer, remove
the PCLTA-20 installation diskette and shut down the computer. Next insert the
PCLTA-20 into a PCI slot and turn the computer back on.
Windows NT 4 and Windows 2000 Software Installation Procedure
To install the PCLTA-20 software on a Windows NT 4 or Windows 2000 PC, follow the
instructions below. The PCLTA-20 software cannot be installed from DOS or a DOS
shell.
!
Only install the PCLTA-20 card after the software has been
installed.
1.
Close all open programs.
2.
Insert the installation diskette into the PC.
3.
Open the Windows Start menu and select the Run command.
4.
When prompted for a program name, enter the following:
a:SETUP.EXE
If necessary, replace a: with the drive letter which corresponds to the drive
containing the PCLTA-20 installation diskette.
5.
2-4
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.
Installing the PCLTA-20 Card
6.
When prompted for a destination directory, enter the desired installation directory.
By default this directory is c:\lonworks, unless previous LON WORKS products
have been installed and registered a different path in the Windows Registry. The
path may be modified using the Browse button; however, if a directory other than
c:\lonworks is chosen, the PCLTA-20 images path will have to be specified to
enable use of the PCLTA-20 card. This is accomplished during PCLTA-20
Configuration. See Chapter 3, Configuring and Testing the PCLTA-20 Adapter.
7.
There is a limit of six (6) PCLTA-20 cards in a single PC.
8.
The installation software for the Windows NT and Windows 2000 versions will issue
a prompt to add a DOS virtual-mode device driver file to the DOS CONFIG.NT file to
support DOS applications calling LON1. This will allow DOS applications to be used
in a Windows NT or 2000 DOS shell/window. For more information see VirtualMode 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-20 installation diskette, turn off power, install the PCLTA-20 card, and
then reboot the computer.
Windows 95/98/Me Software Removal Procedure
To remove the PCLTA-20 software, follow these steps:
1.

5.
If necessary, edit the CONFIG.NT file to remove any references to the
PCLTADOS.SYS driver.
Windows 95/98/Me Virtual-Mode DOS Driver Installation Results
The Windows 95/98/Me PCLTA-20 card installation software will prompt the installer to
automatically add the virtual-mode DOS driver. This driver is small in size, and allows
a DOS session under Windows to have access to the PCLTA-20 through the device
driver running as a part of Windows. The driver will not function unless a Windows
session is running and the PCLTA-20 device driver is installed.
The following line will be added to the CONFIG.SYS file:
DEVICE=<directory of file>\LDVVDD.SYS /Dn /Ln
/Dn
where (n) is 1-9. This defines LON1-LON9 and corresponds to devices 1-9 as
determined by the PCLTA-20 device driver under Windows. This parameter is
optional; the default is “1”.
/Ln
where (n) is 1-9. This defines the logical device 1-9 as determined by the
PCLTA-20 device driver under Windows. This parameter is optional, the
default is the value determined by the /Dn parameter. This allows overriding
the actual device accessed from being based on the /Dn parameter.
For example, using /D9 /L1 will in fact create a DOS driver named LON9 that will
actually access the 1st PCLTA-20 in the system. Without the /L1 parameter you would
access the 9th device, as determined by the /D9 option. These options are typically
needed when more than one LON WORKS network interface is present in the system.
Windows NT and Windows 2000 Virtual-Mode DOS Driver Installation
Results
The Windows NT and Windows 2000 PCLTA-20 installation software will prompt the
installer to automatically add the virtual-mode DOS driver. This driver is small in size,
and allows a DOS session under Windows to have access to the PCLTA-20 card through
the device driver running as a part of Windows. The driver will not function unless a
Windows session is running and the PCLTA-20 device driver is installed.
The following line will be added to the system32 folder under the Windows system
directory:
DEVICE=<directory of file>\PCLTDOS.SYS /Dn
/Dn
2-6
where (n) is 1-9. This defines LON1-LON9 and corresponds to devices 1-9 as
determined by the PCLTA-20 device driver under Windows.
Installing the PCLTA-20 Card
The following is an example of the line that would be added to the CONFIG.NT file:
DEVICE=C:\LONWORKS\BIN\PCLTDOS.SYS /D1

ESD Warning
This product contains devices which are sensitive to static electricity. Before
installing or removing the PCLTA-20 card or the network cables, discharge any
static electricity which may have accumulated to earth ground.
1.
Turn off the PC and remove the power cord.
2.
Open the PC case and locate an empty 32-bit PCI slot. Remove the corresponding
blank panel from the rear of the PC. Set aside the screw.
3.
Insert the PCLTA-20 card into the slot, ensuring that the edge connectors are fully
mated and the slot in the rear panel mounting lug of the PCLTA-20 card is aligned
with the threaded hole in the PC chassis.
If using a Model 74405 PCLTA-20/SMX Interface, or a Model 33100-20 PCLTA-20
Protocol Analyzer, insert the SMX transceiver in accordance with the manufacturer’s
instructions before installing the PCLTA-20—see the LON WORKS® SMX™
Transceiver Installation Instructions document 078-0145-01 version D or later if
using an Echelon SMX transceiver. The height of the PLM-10, PLM-2X, and
PLM-30 Power Line SMX Transceivers is such that two (2) PCI slots must
be allocated for a PCLTA-20 equipped with a PLM transceiver, even though
the card will be plugged into only one slot.
4.
Replace the screw to hold the PCLTA-20 card firmly in place.
5.
Reinsert the power cord and then restart the PC. A New Hardware Found window
will be displayed briefly when Windows recognizes the PCLTA-20 card.
Troubleshooting
As a plug-and-play device, the PCLTA-20 card should operate as desired following
completion of the installation process. If the card does not function correctly, the most
likely causes are system resource constraints or software incompatibilities. These
problems are described in detail in the following sections.
PCLTA-20 PCI Interface User’s Guide
2-7
Installing the PCLTA-20 Card Before Software Installation
The following section applies to Windows 95/98/Me only.
If the PCLTA-20 card was inserted into the PC prior to PCLTA-20 software installation,
the Windows operating system will be unable to associate a device driver with the card.
When Windows 95/98/Me starts up, a New Hardware Found window will appear. Click
the Cancel button, then install the PCLTA-20 software as described above.
If the option “Do not install a driver (Windows will not prompt you again)” was
inadvertently selected, the operating system will mark the PCLTA-20 card as an
unknown device. As a result, the card will not function even if the PCLTA-20 software
is installed. To correct this problem, remove the device using the following steps:
1.
Open the System icon in the Windows Control Panel and select the Device Manager
tab.
2.
Double-click the Other Devices icon.
3.
Select the PCLTA-20 device and click the Remove button.
4.
Install the PCLTA-20 software and reboot the PC.
System Resources
Each PCLTA-20 card requires sixteen contiguous bytes of I/O address space starting on
a modulo-4 based address, i.e., an address evenly divisible by 4. A dedicated interrupt
request (IRQ) is also required for each PCLTA-20 card used.
Solving IRQ and I/O Conflicts under Windows 95/98/Me
I/O resource problems are rare under Windows 95/98/Me for the PCLTA-20 card since
the card can handle a wide range of I/O settings. However, IRQ resource problems may
occur more often in multimedia computers which may have very few spare IRQs. The
Windows 95/98/Me operating system handles most allocations of IRQs, but there are
some instances where the operating system cannot properly allocate interrupt requests.
When the Windows 95/98/Me Device Manager does not locate a free IRQ for a newly
inserted PCLTA-20 card, it will not assign an IRQ to the card. As a result, there may
be no indication to the user that a problem has occurred, since no true resource conflict
has occurred. This is a consequence of the PCLTA-20 card’s ability to be assigned any
of the system’s 16 IRQs.
IRQ usage in the system can be determined by opening the System icon in the Windows
Control Panel. The Device Manager tab allows viewing of devices by type or connection.
The PCLTA-20 LON WORKS Network Interface device icon is found under the
LonWorks Interface device type. If there is a problem with the card, there will be a red
circle with an exclamation point next to its icon.
IRQ resource problems may generally be resolved by disabling another device in the
system. More information can be found in the Hardware Conflict troubleshooting
portion of the Windows 95/98/Me on-line Help file.
2-8
Installing the PCLTA-20 Card
Access the hardware conflict troubleshooter through the procedure outlined below:
1.
Open the Windows 95/98/Me on-line help by clicking the Windows Start button
and selecting Help.
2.
In the Help Topics window, choose the Contents tab, or from another Help
window, choose the Contents button.
3.
Double-click the Troubleshooting topic, and then select the If You Have A
Hardware Conflict help topic.
Extensive trouble-shooting documentation can be found in the Microsoft Windows
95/98/Me Resource Kit Help File. This help file is part of the Windows 95/98/Me
Resource Kit, which is available from Microsoft.
If a DOS real-mode driver is in use for a specific device that is installed in the PC,
Windows 95/98/Me may not know about that device’s resource requirements. Unlike
Windows driver conflicts, this problem is difficult to diagnose.
There are rare I/O conflict situations of which the Device Manager may be unaware.
Such a conflict may occur when an I/O resource is not properly specified for a device,
and a new driver overlays onto the true I/O space of that device. In the event of such a
conflict, it may become necessary to manually reserve I/O or IRQ resources using the
Device Manager. This process is described in the Windows 95/98/Me on-line Help.
Once these resources have been reserved, the Device Manager will recognize and
attempt to resolve any resource conflicts between the DOS driver and any Windows
drivers. If a conflict still occurs, it will be visible, and may be resolved as described in
Solving IRQ and I/O Conflicts under Windows 95/98/Me earlier in this chapter.
If a device resource requirement is hardwired into the PC (i.e., configured by a jumper
or not modifiable from the system BIOS ) then there is little that the Windows 95/98/Me
operating system can do to free the resources.
Common Resource Problems under Windows 95/98/Me
The following situations produce an additional drain on system resources that may be
hard to manage. Conflicts arising from these situations can generally be resolved by
selectively disabling devices to free up the required resources.
•
COM ports that may not have a connector, but are consuming resources and
cannot be disabled through the BIOS
•
Unused IDE controllers that can not be disabled through the BIOS
•
Unused/nonexistent PS/2 mouse ports
•
Sound cards that support both 8-bit and 16-bit compatibility modes, consuming
two IRQs
PCLTA-20 PCI Interface User’s Guide
2-9
An additional problem often associated with sound cards is the improper reporting of
I/O resource usage. This problem may be recognized by examining a device’s I/O
address allocation for unusual one-byte assignments (since devices typically use
more). For example, if a device’s stated I/O range is 0x201-0x201 but its actual
range is 0x201-0x204, a conflict will occur if the PCLTA-20 card is assigned an I/O
range of 0x204-0x207. If this problem is suspected, manually move the PCLTA-20
card’s I/O range to a safer location to prevent I/O overlap.
Solving Conflicts under Windows NT 4
The PNPLON.SYS device driver works with the Windows NT operating system to
locate PCLTA-20 cards. The driver is completely Plug n’ Play, and because the device
is a PCI card, the system BIOS will determine a useable I/O port and IRQ setting.
There is no user-configurable resources setting from the Windows NT operating system.
If more control is required over the choice of IRQs used for the PCLTA-20, there is an
optional system setting that can be used. The Preference button on the LONWORKS Plug
‘n Play control panel brings up a self-explanatory dialog that allows the setting of the
preferred and alternative IRQ list.
The Preference button also allows a choice of the numeric base for the device naming
convention, i.e, the value of x in LONx. By default this will start at “LON1”. This
could create a conflict if another device driver is also trying to create a device named
“LON1” (such as a PCNSS/PCNSI driver). In this case choose another value.
If other values are chosen for the device naming convention then you may want to
assure that the DOS driver defined in your CONFIG.NT file reflects this setting. It is
this DOS driver in the CONFIG.NT file that defines the device name used by 16-bit
Windows applications running under NT, so such an application will refer to devices
named “LON1”, “LON2”, and so on.
The first place to go for information if problems arise should be the Event Log under
System Events.
Software Compatibility
The PCLTA-20 software is designed to be compatible with LON WORKS software.
However, the following issues may arise when using the PCLTA-20 adapter with some
software.
Device Name Aliasing under Windows 95/98/Me
The PCLTA-20 card should operate with most third-party LON WORKS software.
However, some 16-bit Windows applications are limited in the device names that can be
selected. For example, only the names “LON1” through “LON9” may be available,
preventing the use of a PCLTA-20 card. This problem can be corrected through the use
of device name aliasing. To create a device alias, follow these instructions
1.
Open the file named ECHELON.INI, which should reside in the Windows directory.
If this file does not exist, then create one with a text editor.
2.
Create a driver alias section in the file, by adding the following line:
[DRIVERALIAS]
2-10
Installing the PCLTA-20 Card
3.
On the following line, add the following driver alias:
aliasname=devicename
where aliasname is the device name accessed by the software, such as “LON1”,
and devicename is the device to be used.
4.
Add additional aliases, as necessary.
The following example creates a device alias that routes all service requests for LON1 to
the PCCLON1 PCLTA-20 card.
[DRIVERALIAS]
LON1=PCCLON1
LonManager ISA Protocol Analyzer Compatibility
The device driver for the PCLTA-20 card and the driver for the Model 33100-00
LonManager Protocol Analyzer ISA-bus card share the same Windows VxD identifier.
As a result, both types of cards cannot run on a PC at the same time. So, the PCLTA20 installation software will comment out the SYSTEM.INI entry that loads the ISAbus driver.
The LonManager Protocol Analyzer software does not run under Windows Me, Windows
NT 4, or Windows 2000.
PCC-10 and PCLTA-10 Compatibility
The LON WORKS Plug n’ Play control panel can only support one type of downloadableimage network adapter at a time unless the system image files are copied and renamed.
PCC-10, PCLTA-10, and PCLTA-20 cards may not be used or installed in the same PC
unless the system image files are copied and renamed.
Plug ‘n Play Issues Under Windows NT 4
If both a PCLTA-20 and PCNSI card are running and both devices have created
"\\.\Lon1.0" values for the device key then a named device conflict will occur. The only
option is to change the device name for the PCLTA-20 card. To do this, call up the
LON WORKS Plug ‘n Play control panel and click the Preferences button. This will
present a window with which the name can be changed, e.g., 'LON2'. Reboot the PC.
The PCLTA-20 card will now be renamed LON2 and the named device conflict will be
resolved.
Under certain circumstances the LON WORKS Plug ‘n Play control panel diagnostics
functions states that the PCLTA-20 and driver are functioning; however, the
PCLTA-20 PCI Interface User’s Guide
2-11
LonMaker Integration Tool or any other LNS tool does not work. You will notice that
when the network is open the tool indicates that it is unable to communicate with the
PCLTA-20. This is because the PCLTA-20 card features a downloadable firmware
image and the LON WORKS Plug ‘n Play control panel must be reconfigured to support
LNS. The NI Application must read PCL10VNI, and not PCC10L7 or PCL10L7.
If, after pressing the test button after installation of a PCLTA-20 card, an **ErrorImage Load Failure** message is reported, then there is either an I/O conflict with the
PCLTA-20 card, or the card is broken. If there is an I/O conflict, then Windows NT is
not granting an unused I/O port to the PCLTA-20 driver. To rule out a broken card,
check the card using a Windows 95/98/Me or Windows 2000 configuration known to be
reliable.
Automatic Flush Cancel Issues
If the PCLTA-20 card appears to install and test normally, but still will not
communicate on the network, check to be sure that the Automatic Flush Cancel
checkbox in the LON WORKS Plug ‘n Play control panel applications is still in its
default (set) state. For more information, see the Automatic Flush Cancel section in
Chapter 3.

Configuring and Testing the
PCLTA-20 Card
This chapter explains how to configure and test the PCLTA-20 card
using the Control Panel application installed in Chapter 2.
PCLTA-20 PCI Interface User's Guide
3-1
PCLTA-20 Configuration
PCLTA-20 configuration is accomplished by using the LON WORKS Plug ‘n Play
control panel application. Open the control panel application by selecting the
LON WORKS ® Plug ‘n Play icon in the Windows Control Panel.
LON WORKS
Plug ‘n Play
logo
Figure 3.1 PCLTA-20 Control Panel and Icon
The LON WORKS Plug ‘n Play control panel application is divided into three parts: a
device selection area, a general settings area, and a control section. The device
selection area contains configuration settings and diagnostic controls that are specific
to an individual PCLTA-20 card and its device driver. The general settings area
contains settings for all PCLTA-20 cards used with the PC. The control section
contains buttons for accepting or canceling the changes made in the control panel, as
well as a Help button.
PCLTA-20 Initialization
In most cases, PCLTA-20 initialization occurs automatically upon installation of the
card and subsequent power-up of the computer. Manual initialization will be required
following software installation to a directory other than c:\lonworks, or following the
moving of the PCLTA-20 system images.
To manually initialize the PCLTA-20 card, verify that the control panel application’s
System Image Path entry is correct, then click the Apply button.
An error will be reported if an attempt is made to view the transceiver type before the
PCLTA-20 card is initialized. Testing the card with the Diagnostics button, as
3-2
Configuring and Testing the PCLTA-20 Card
suggested by the error message, produces the diagnosis: “Image file not found.” In this
case, return to the control panel application’s main window and manually initialize the
PCLTA-20 card.
Device Specific Settings
The PCLTA-20-specific options consist of five separate controls (figure 3.2). These
controls are defined as follows:
Figure 3.2 PCLTA-20-specific Controls
Device Selected
Controls which PCLTA-20 card is selected for configuration. The PCCLON1 and
PCCLON2 drivers are installed by the installation software. If additional drivers have
been manually installed, they also will be available.
Automatic Flush Cancel
For non-LNS images, this function controls whether the device driver will
automatically force the network interface for the selected PCLTA-20 card to leave the
post-reset flush state whenever it is reset; an LNS network interface does not and
cannot come up in the flush state. The post-reset flush state prevents any inbound or
outbound network traffic following a reset. If this box is not checked, it is up to
the client application to manage this state. If it is checked, the device driver will
automatically allow network traffic to resume. The default is checked.
NI Application
Controls the type of image or application to be used on the PCLTA-20 card. This
selection is handled automatically by the protocol analyzer software. For all other
applications, a PCLTA-20 card can only hold one image at a time. Loading a new
image will replace the currently loaded image. The choices for these images are
determined by the image files (.NBI extension) found in the system image path
specified under General Settings. Some of the possibilities include the following:
•
PCL10VNI, the LNS Fast Network Interface image (for use with LNS 3 and
newer)
PCLTA-20 PCI Interface User's Guide
3-3
•
NSIPCLTA, the LNS network interface image (for use with LNS 1 and LNS 2
only)
•
PCC10L7, the basic network interface application image
Transceiver
Opens the PCLTA-20 Transceiver dialog (figure 3.3). Choosing this option will retrieve
the transceiver configuration of the selected PCLTA-20 card. If there is no PCLTA-20
card currently installed in a PCI-bus slot, a message appears stating that the operating
system has removed, or has not loaded, the PCLTA-20 device driver.
Figure 3.3 PCLTA-20 Transceiver Dialog Box
The Transceiver value specifies the transceiver type for the selected PCLTA-20 card.
The default transceiver is a TP/FT-10 compatible transceiver. Other standard
transceiver configurations, and a custom configuration, may be chosen. The Custom
Properties values are not accessible unless the Custom transceiver type is selected: you
cannot modify the transceiver type as it is a product of the transceiver ID (XID),
however, if the XID is custom then you can modify the fields using the Custom
Properties dialog box. If an incorrect transceiver type error is received while modifying
the transceiver type, click the Apply button, then proceed to modify the transceiver
type.
The Custom Properties area contains custom transceiver properties. The information
in this area reflects the current configuration within the PCLTA-20 card. It will not
change until a transceiver is selected, and then configured using the OK or Apply
buttons.
3-4
Configuring and Testing the PCLTA-20 Card
When configuring a custom transceiver or adding custom parameters for a standard
transceiver, the Custom Properties Raw Data values must be entered as hexadecimal
values separated by dashes. Further explanation of Raw Data values can be found in
the LonBuilder® User’s Guide.
Diagnostics
Opens the PCLTA-20 Diagnostics dialog. For more information, see the section on
PCLTA-20 Diagnostics.
General Settings
The PCLTA-20-generic options consist of four controls (figure 3.4). These controls are
defined as follows:
Figure 3.4 PCLTA-20 Generic Controls
System Image Path
Specifies the full directory path for the PCLTA-20 system images. This path is set by
the PCLTA-20 Installation Software but may be modified by the user.
Layer2 and Layer6 Buffering
Controls the number of 4Kbyte operating system pages that are allocated for message
buffering within the driver. The Layer2 setting is used by the PCLTA-20 protocol
analyzer only and should not be modified from the default of 20 pages. The Layer6
setting is used for all other system images. The default setting of Layer6 Buffering is 6
pages. This value should be appropriate for most applications; embedded systems may
need to change the number of buffering pages.
PCLTA-20 PCI Interface User's Guide
3-5
Enable PC Card Reset
This control is not used with the PCLTA-20 card. It is provided for owners of the
PCC-10 PC Card (PCMCIA card) and controls whether the hardware reset line is
enabled. The state of this checkbox is irrelevant to the operation of the PCLTA-20
card.
PCLTA-20 Diagnostics
A number of diagnostic and testing services are provided by the PCLTA-20 control
panel application. Clicking the Diagnostics button in the main control panel window
displays the PCLTA-20 Diagnostics dialog. This dialog contains buttons for the
diagnostic commands and displays the version number and current status of the
PCLTA-20 device driver. If no PCLTA-20 card is installed in a PCI-bus slot, the
Diagnostics window will display “(no driver found)”.

Comm
!
The Comm button is not available if you are using the PCLI0VNI
image. If you are using the PCL10VNI image, first select the
NSIPCLTA image, click Apply, run the Comm test, then reselect
the PCL10CNI image, and click Apply.
The Comm button verifies communications between the PCLTA-20 card and another
device on the network. When this function is chosen, a dialog will appear asking for
confirmation of this command, as follows:
This procedure will configure the Network Interface for a zerolength domain if it is not already configured. Do you want to
proceed?
Choosing OK causes the control panel to first check the network interface for the
configured state. If it is already in the configured state, it will not be modified further.
If it is not in the configured state it will install the network interface with a zero-length
domain on index 0, a subnet of 1, and a node ID of 126, and then change its state to
configured.
Once the device is in the configured state, the control panel application enters the
receive-ready state and displays the following message while waiting for a service pin
message from another device on the network:
Now waiting for a service pin message.
Once the service pin is activated on the other device and a service pin message is
received, the control panel application sends a diagnostic message to the other device
using Neuron ID addressing. It will repeat this message, referred to as a “ping,” once

per second until either the OK or the Quit button is chosen (the Quit button will appear
in place of the Comm button).
This series of tests confirms that the PCLTA-20 card can be configured and can
communicate with a device on the network. The Comm function is intended to
eliminate the PCLTA-20 card, the card drivers, the network connection, the hardware
of the other device, and the topology configuration from the list of possible problem
points or points of failure during network troubleshooting. The Comm function test
does not eliminate the possibility that the wrong type of media has been used. Be sure
that the medium is suitable for use with the selected channel type. The Comm
function also does not eliminate the possibility of a missing or improper network
termination.
The network wiring may work for this test but may fail if multiple devices are
communicating. Be sure to verify that the proper termination is used when
troubleshooting communication problems.
The Comm feature is not designed to work across routers.
Service
!
The Service button is not available if you are using the PCLI0VNI
image. If you are using the PCL10VNI image, first select the
NSIPCLTA image, click Apply, click the Service button, then
reselect the PCL10CNI image, and click Apply.
The Service button will cause the PCLTA-20 card to broadcast a service pin message on
the network. The service pin message will not be sent if the card is in the post-reset
flush state (see Automatic Flush Cancel).
Restart
The Restart button clears the card’s Neuron Chip image and places the device into the
boot state. This is the device state found following a re-boot of the Windows operating
system. When this function is chosen a dialog will appear asking for confirmation of
this command.
Reset
The Reset button causes a reset of the card’s Neuron Chip, but does not clear its
Neuron Chip image.

P1 and P2 PCI Bus Connector
The pinout of the P1 and P2 connector terminals is the standard pinout for the 32-bit
PCI bus used in Windows-compatible PCs. The power drawn from the host is 250mA @
5VDC, typical. Actual power consumed for the SMX or protocol analyzer card will vary
according to the power needs of the selected SMX transceiver.
Network Connector
The PCLTA-20 Model 74401-74403 cards are supplied with a removable two terminal,
Weidmüller BLA connector (BLA 2B OG) for the network connection. The wiring to the
twisted pair channel is polarity insensitive. The connector will accept 12 to 26AWG
(1.2mm to 0.45mm) wire. See the Junction Box and Wiring Guidelines for Twisted
Pair LON WORKS Networks, LON WORKS FTT-10A Free Topology Transceiver User’s
Guide or the LON WORKS TPT Twisted Pair Transceiver Module User’s Guide for
information on suitable cables and cable distances.
The PCLTA-20 Model 74404 card is supplied with a removable three terminal,
Weidmüller BLA connector (BLA 3B OG) for the RS-485 network connection. The
wiring to the RS-485 twisted pair channel is polarity sensitive. The connector will

potential between different devices.
Mechanical Considerations
PCLTA-20 Models 74401 – 74404 measure 3.87” (9.8cm) H x 5.20” (13.2cm) L. Model
74405 and the PCLTA-20 Protocol Analyzer Card measure 3.69” (9.4cm) H x 7.36”
(18.7cm) L. All models are equipped with a full-height chassis bracket. If a PLM SMX
transceiver is used with an SMX or protocol analyzer card, two PCI slots must be
dedicated to the card due to the wider-width of the assembled PCLTA-20/PLM card.
