2-10 Installing the PCLTA-20 Card
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 LONWORKS 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 LONWORKS 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]
