National Instruments Corporation 2-3 PC-LPM-16/PnP User Manual
Base I/O Address and Interrupt Selection
You can configure your PC-LPM-16PnP to use base addresses in the
range of 100 to FFF0 hex. The PC-LPM-16PnP occupies 16 bytes of
address space and must be located on a 16-byte boundary. Therefore,
valid addresses include 100, 110, 120…, FFE0, FFF0 hex. This
selection is software-configured and does not require you to manually
change any settings on the board.
The PC-LPM-16PnP can use interrupt channels 3, 4, 5, 6, 7, and 9.
There are different ways to assign the base address to your board:
• For Windows 95, the base address and interrupt should be set
automatically. However, if you want to view or change these
settings, you can set the board resources using the
Device
Manager
. Windows 95 will automatically allocate resources, but
these can be changed in the
Device Manager
:
a. Click the right mouse button on
My Computer
to bring up
system properties.
b. Select
Device Manager
.
c. Select
Data Acquisition Devices
.
d. Select the
PC-LPM-16
.
You can change address and interrupt settings on the
Resources
page.
• For Windows 3.10 or 3.11, you can use the NI-DAQ Configuration
Utility (formerly
WDAQCONF
) to assign the board resources. If a
standard configuration utility is present in the system, you will not
be able to modify the board resources.
• You can use a standard configuration utility like Intel ISA
Configuration Utility (ICU). ICU dynamically assigns the base
address to your board when you boot up the computer. You can also
lock the board resources when you use ICU. For additional
information on ICU, contact Intel Corporation for a copy of Plug
and Play Specification version 1.0a.
