PCLTA-20 Adapter User’s Guide 2-11
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]
3. On the following line, add the 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 PCLTA-20 adapter PCCLON1.
[DRIVERALIAS]
LON1=PCCLON1
LonManager Protocol Analyzer Compatibility
The device driver for the PCLTA-20 adapter and the driver for the 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 PCLTA-20
installation software will comment out the
SYSTEM.INI
entry that loads the ISA-bus
driver.
The LonManager Protocol Analyzer does not run under Windows NT.
PCC-10 and PCLTA-10 Compatibility
The L
ON
W
ORKS
Plug n’ Play control panel can only support one type of
downloadable-image network adapter at a time unless the system image files are
copied and renamed. PCC-10 cards, PCLTA-10 adapters, and PCLTA-20 adapters
may not be used or installed in the same PC unless the system image files are copied
and renamed.
WLDV Versions (Windows 95/98 only)
Older versions of Echelon’s
WLDV.DLL
file do not support the PCLTA-20 adapter. If
an older version (version 2.54 or earlier) of the file is inadvertently copied into the
WINDOWS\SYSTEM
directory, the PCLTA-20 adapter will be unable to operate.
Should this occur, reinstall the PCLTA-20 software to update
WLDV.DLL
.
Under Windows NT, older versions of WLDV.DLL will still work via DPMI.
Plug ‘n Play Issues Under Windows NT
If both a PCLTA-20 and PCNSI 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. To do this, call up the
L
ON
W
ORKS
Plug ‘n Play control panel and press the Preferences button. This will
present a screen with which the name can be changed, e.g., 'LON2'. Reboot the PC.
