NI PC-LPM-16/PnP Installation and Configuration Multifunction I/O Board for the PC

Hardware Installation

You can install the PC-LPM-16PnP in any available expansion slot in

your computer. The following are general installation instructions, but

consult your computer user manual or technical reference manual for

specific instructions and warnings.

1. Turn off and unplug your computer.

2. Remove the top cover or access port to the I/O channel.

3. Remove the expansion slot cover on the back panel of the computer.

4. Insert the PC-LPM-16PnP board into any 8-bit or 16-bit slot. It may

be a tight fit, but do not force the board into place.

5. Screw the mounting bracket of the PC-LPM-16PnP board to the

back panel rail of the computer.

6. Replace the cover.

7. Plug in and turn on your computer.

The PC-LPM-16PnP is installed.

Software Installation

If you are using NI-DAQ, refer to your NI-DAQ release notes to install

your driver software. Find the installation section for your operating

system and follow the instructions given there.

If you are using LabVIEW, refer to your LabVIEW release notes to

install your application software. After you have installed LabVIEW,

refer to the NI-DAQ release notes and follow the instructions given

there for your operating system and LabVIEW.

If you are using LabWindows/CVI, refer to your LabWindows/CVI

release notes to install your application software. After you have

installed LabWindows/CVI, refer to the NI-DAQ release notes and

follow the instructions given there for your operating system and

LabWindows/CVI.

If you are a register-level programmer, refer to Appendix D, Register-

Level Programming, for software configuration information.

Board Configuration

Plug and Play

The PC-LPM-16PnP is fully compatible with the industry-standard

Intel/Microsoft Plug and Play Specification version 1.0a. A Plug and

Play system arbitrates and assigns resources through software, freeing

you from manually setting switches and jumpers. These resources

include the board base I/O address and interrupt channels. Each

PC-LPM-16PnP is configured at the factory to request these resources

from the Plug and Play Configuration Manager.

The Configuration Manager receives all of the resource requests at

startup, compares the available resources to those requested, and

assigns the available resources as efficiently as possible to the Plug and

Play boards. Application software can query the Configuration

Manager to determine the resources assigned to each board without

your involvement. The Plug and Play software is installed as a device

driver or as an integral component of the computer BIOS.

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
