Echelon LonMaker - Manual (Page 368)

352 Appendix B - Installing Network Interfaces
Windows does not load the device driver for the PCC-10 card until it discovers the first PCC-10 card.
Likewise, when you remove the last PCC-10 card, Windows unloads the device driver, thus freeing
any system resources it was using.
Each PCC-10 card requires a single, dedicated interrupt request (IRQ) and four contiguous bytes of I/O
address space starting on a modulo-4-based address.
If you remove a PCC-10 card while an application is using the card, Windows will lose
communication with the device, which cannot be restored by re-inserting the card. Some applications
will display unusual behavior, and will not properly function. Any application using the PCC-10 card
must be restarted if a PCC- 10 card has been removed to ensure proper operation of the device and
software.
The first time you insert a PCC-10 card into a running computer, a window will appear with the words
“Echelon Corp.- PCC-10.” Another window will appear stating that the Windows operating system is
building a new database from the device information installed by the PCC-10 installation diskette.
You can configure the new hardware when the computer has finished writing the device information.
Configuring the PCC-10 Network interface
Once the PCLTA-10 hardware has been installed, you must load the PCC10VNNI firmware image to

Diagnostics. If the PCC-10 software and hardware installation has proceeded correctly, the
following dialog appears (refer to the PCC-10 online help if it does not appear).
