ESD Precautions
The boards have integrated circuits sensitive to static electricity. To avoid damaging chipsets
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 will help to discharge any static electricity on a
human body.
When handling boards and components, wear a grounding wrist strap available from
most electronic component stores.

1.1 General Description
The AX92352 integrates advanced vision I/O capabilities for machine vision applications,such
as synchronizing multiple frame grabbers in line scan and multiple cameras inarea scan. It
provides 2-CH encoder input with the FIFO function to achieve the tasks of position
comparison and linear trigger. It also supports trigger I/O with a microsecond-scale real-time
control camera to capture images, as well as isolated DIO that can be used with other devices
for your vision cases. The AX92352 vision I/O card can fit in the PCI Express slot of any vision
control system. It can also be used with an optional add-on module AX92353, which provides
LED output support to meet further application needs. These functions can simplify the
deployment of your machine vision platform.
