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.

Non-Plug and Play

To configure the non-Plug and Play PC-LPM-16 board, refer to
