INTRODUCTION
INTRODUCTION
The PCI bus multi-8255/8254 adapter is a 32 bits PCI bus
adapter with Plug and Play (PnP) features, it is a programmable
I/O interface for PC/486, Pentium or compatible computers.
The PnP features let hardware configuration for IRQ and I/O
address is detected by BIOS automatically, you don’t need set
switch and jumper.
The PCI bus multi-8255/8254 adapter pro ides total 24 digital
I/O ports, each I/O port contains 8 I/O lines, and can be set
either input or output by the user’s program. Two 8254 on
board chips pro ides six programmable inter al timer/counter.

HARDWARE INSTALLATION
HARDWARE INSTALLATION
Your PCI bus multi-8255/8254 adapter is designed to be
inserted in any a ailable PCI slot in your PC/486, Pentium or
compatibles. In order to gain access to the expansion slots,
follow the steps listed below:
1. Turn off all power to your computer and all peripheral
de ices before installing your multi-8255/8254 adapter.
2. Remo e the co er of the computer.
3. Insert the multi-8255/8254 adapter into any a ailable
PCI slot. Make sure the adapter is firmly seated in the
chosen slot.
4. Replace the co er of the computer.
5. Connects the expansion cables.
6. Turn on the power of your computer, the PnP features
will recognize the multi-8255/8254 adapter.

4.2 DIP Switch
ON 1 2 3 4
The switch is used to identify card number, default setting is
card 1. There are two methods to set the card number:
a. PnP mode
Just plug in PCI bus adapter into PCI slot, the PCI BIOS will
allocate I/O address to each adapter automatically and assign
card number start from 0 to each adapter. Howe er, if you
plug in more than one adapter, please set whole adapters to
card number 1 (default setting), then use software tools to
distinguish port id.
