ESD Precautions
Integrated circuits on computer boards are sensitive to static
electricity. To avoid damaging chips from electrostatic discharge,
observe the following precautions:
nDo not remove boards or integrated circuits from their
anti-static packaging until you are ready to install them.
nBefore handling a board or integrated circuit, touch an
unpainted portion of the system unit chassis for a few
seconds. This helps to discharge any static electricity on
your body.
nWear a wrist-grounding strap, available from most
electronic component stores, when handling boards and
components.

iv
Unpacking
The AX5214P is packed in an anti-static bag. The DIO board has
components that are easily damaged by static electricity. Do not
remove the anti-static wrapping until proper precautions have
been taken. Safety instructions in front of this User’s Manual
describe anti-static precautions and procedures.
Inventory and Inspection
After unpacking the DIO board, place it on a raised surface and
carefully inspect the board for any damage that might have
occurred during shipment. Ground the board and exercise
extreme care to prevent damage to the board from static
electricity.
Integrated circuits will sometimes come out of their sockets
during shipment. Examine all integrated circuits, particularly the
BIOS, processor and keyboard controller chip to ensure that they
are firmly seated.
The AX5214P 48 Bits DIO Board with PCI BUS package
includes the following:
nAX5214P Board
nRP-9 4.7K (A) 1/8w x 6 pcs
nAS59099 DAC Driver CD
Make sure that all of the items listed above are present.
What To Do If There Is A Problem
If there are damaged or missing parts, contact your supplier
and/or dealer immediately. Do not attempt to apply power to the
DIO board if there is damage to the printed circuit board.

General Description
1.1 Introduction
The AX5214P is a 48-bit digital input and output board that plugs
into the computer via PCI (Peripheral Component Interconnect)
slot. The board can be used with TTL low-level input/output
circuitry or with solid state relay module (8-, 16-or 24-channel
versions) providing 2500V isolation for interfacing with high
level AC and DC signals.
The 48 digital I/O lines are arranged into two separated groups.
Each group, emulates 8255 PPI (Programmable Peripheral
Interface) chip mode 0 but with stronger driver capability, is
further divided into three 8-bit ports (port A, port B and port C).
These ports can be functionally programmed as either digital
inputs or digital outputs.
There is a unique feature associated with AX5214P: An interrupt
on change of state. Interrupt occurs when port C bit 3 or bit 7 of
each group changes state. This feature frees up the PC to do other
activities since there is no need to poll the digital input port for an
event to occur.
1.1.1 Applications
Sense and Control High Level Signals throughI/O module
Sense Low-level (TTL) switches or signals
Drive Indicator Light or Control Recorders
Parallel Data Transfer to PC
