In the LonWorks Plu

control panel window, changing the NI Applicatio
fro
PCL10VNI to NSIPCLTA would result in a “access is denied” message. (43754)
The Windows Compatibility Wizard appears after running the LonWorks Interfaces control
panel asking whether the “unknown program” ran successfully. (43772)
PCC-10 card hardware interrupts consume 98% CPU time after resuming from Sleep/Hibernate
mode. (46103)
The PCC10L7 image has been added back to the available images for the PCC and PCLTA cards. This
image is not used by LNS applications, but some legacy applications require it. (42584)
In some cases, OpenLDV 3.3 installation can cause PCLTA-10, PCLTA-20 and PCC-10 card device driver
entries to disappear after reboot. (42583)
The PCLTA-20 driver does not recognize the new RoHS-compliant PCLTA-20/SMX network interface card.

This section lists the changes included in OpenLDV 3.3.
11.1 Certified PCLTA-20, PCLTA-21, and PCC-10 Drivers
The Echelon network interface cards formerly supported by a separate driver installation have been
incorporated into the OpenLDV installation. The driver for these cards has been certified by Microsoft for
compatibility with the Windows 2000, Windows XP, and Windows 2003 operating systems. The driver has
not been certified for compatibility with Windows Vista. These interfaces are still defined and managed
through the LonWorks® Plug n’ Play item in the Windows Control Panel.
11.2 Problems Fixed
The following problems have been fixed in OpenLDV 3.3:
LonScanner packet timestamp can drift significantly. (40860)
Windows handle leak when repeatedly opening and closing driver sessions. (39204)
The following are known OpenLDV problems and their workarounds. The numbers in parentheses at the end
of the problem descriptions are Echelon's internal problem tracking IDs.
12.1 Interaction with LNS 3, Service Pack 8, Update 1
Echelon released a patch update to the LNS product in March 2003 named “LNS 3, Service Pack 8, Update
1” (LNS3SP8U1) that is not forward compatible with OpenLDV 3.3 and later releases.
This patch will cause problems for any computer with OpenLDV 4.0 installed, if it is installed after OpenLDV
4.0. It will overwrite the newer OpenLDV components, causing them to revert back to older versions. This
will cause all functionality added in OpenLDV 3.3 through 4.0—such as USB network interface support—to
