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.

2.4.1.3 VGA/Flat Panel Connector: VGA1, CN1, CN2
The SBC82621 has three connectors that support CRT VGA
and flat panel displays, individually or simultaneously. VGA1 is
a standard 15-pin pin header connector commonly used for the
CRT VGA display, and CN1 (44-pin) CN2 (20-pin) are dual-in-
line headers for flat panel connection. Configuration of the
VGA interface is done via the software utility and no jumper
setting is required. The following two tables are the pin
assignments for the CRT/VGA connector and the flat panel
connector.
