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.
