Safety Precautions

Warning!
Always completely disconnect the power cord from your chassis
whenever you work with the hardware. Do not make connections
while the power is on. Sensitive electronic components can be
damaged by sudden power surges. Only experienced electronic
personnel should open the PC chassis.

Caution!
Always ground yourself to remove any static charge before
touching the CPU card. Modern electronic devices are very
sensitive to static electric charges. As a safety precaution, use a
grounding wrist strap at all times. Place all electronic components
in a static-dissipative surface or static-shielded bag when they are
not in the chassis.

Chapter 2 Installations
2.1 I/O Equipment Installation
2.2 12V DC-IN
The Motherboard allows plugging 12V DC-IN jack on the board without additional
power module converter.
2.3 Serial COM ports
There are two built-in COM port (RS232/422/485 selectable; one with 9-pin D-Sub
and the other with pin-header) on TA33. When an optional touch-screen is ordered
with PPC, serial com port can connect to a serial or an optional touch-screen.
2.4 Ethernet interface
The Motherboard is equipped with one RJ-45 jack which is fully compliant with the
PCI 10/100/1000 Mbps Ethernet protocol. The LAN port also supports PoE function
(Power over Ethernet; 802.3AT).
2.5 USB ports
Six USB devices (Four with pin headers) may be connected to the system though an
adapter cable.The USB ports support hot-plug connection.
2.6 Audio function
The audio interface includes three pin-header connectors on board: two for Stereo
Speaker out (L/R) and one Mic in.

2.8 Jumper Setting
A pair of needle-nose pliers may be helpful when working with jumpers. If you have
any doubts about the best hardware configuration for your application, contact your
local distributor or sales representative before you make any changes. Generally, you
simply need a standard cable to make most connections.
The jumper setting diagram is as below. If a jumper shorts pin 1 and pin 2, the setting
diagram is shown as the right one.
