ESD Precautions
Integrated circuits on computer boards are sensitive to static
electricity. To avoid damaging chips from electrostatic discharge,
observe the following precautions:
Do not remove boards or integrated circuits from their anti-static
packaging until you are ready to install them.
Before 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.
Wear a wrist-grounding strap, available from most electronic
component stores, when handling boards and components.

Unpacking
The AX5410P is packed in an anti-static bag. The 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.
After unpacking the 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.
After unpacking the AX5410P, check and see if the following
items are included and in good condition. If any of the items is
missing or damaged, notify your dealer immediately.

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
board if there is damage to any of its components.

Introduction
1.1 General Description
The AX5410P provides 16 isolated digital input channels. It
plugs directly into any 32-bit PCI Bus. The 16 opto-isolated D/I
channels are ideal for sensing digital inputs, and provide 1000V
of isolation. Each channel is optically isolated from system
circuit and other input channels. You can configure each input
channel individually by setting the jumpers for either voltage
mode or dry contact mode input operation. The configuration of
a channel in voltage mode may either be DC signal or AC signal
input, depending on the jumper setting. In the past, we usually
perform polling in order to acknowledge status change of input
signal, causing a waste in CPU time. Now, AX5410P offers an
onboard intelligent detector circuit that asserts an interrupt
signal to CPU when change of input signal occurs. For this
reason, the AX5410P supports 16 onboard LEDs that displays
the input channel’s status.
