Pentium Third Serial Port Installation
Introduction
This document explains how to add a third serial port to P3, P4, or P5
PowerStations that have a Pentium CPU card. It includes instructions for
opening the PowerStation, reconfiguring the System Support card, estab-
lishing communication for COM2 on the CPU card, reinstalling the
System Support card, installing the third COM port, closing the PowerSta-
tion, enabling COM3 during startup, reconfiguring the PowerStation’s
touchscreen, and having Windows®detect the new serial port.
Warning You must observe normal precautions against electrostatic
discharge to prevent damage to the PowerStation.
Electrostatic Discharge Precautions
Modern integrated electronic devices, especially CPUs and memory chips,
areextremelysensitivetoelectrostaticdischarges(ESD)andfields.Before
you disassemble the PowerStation, be sure to follow these simple precau-
tions to protect you and the PowerStation from harm resulting from ESD.
1. To avoid electric shock, always disconnect power from the PowerSta-
tion before you remove the back cover. Do not touch any components
of the CPU card or other cards while the PowerStation is on.
2. Disconnect power before making any hardware configuration chang-
es. The sudden rush of power as you connect a jumper or install a card
may damage sensitive electronic components.
3. Only handle internal components in an ESD-safe location, using ap-
propriate grounding methods.
4. Always ground yourself to remove any static charge before you touch
the CPU card.
5. Be particularly careful not to touch the chip connectors.
6. Keep any card in its anti-static packaging when it is not installed in the
PowerStation and place it on a static dissipative mat when you are
working on it.
7. Wear a grounding wrist strap for continuous protection.
