TABLE OF CONTENTS
CHAPTER 1: GENERAL INFORMATION......................................1
Before removing the card from the anti-static protective packaging:
• Discharge any static electricity buildup on your body by
touching a large grounded metal surface or the metal
chassis on equipment connected to earth ground by a 3-wire
power cord.
• Avoid touching the gold connectors or other parts on the
card except as necessary to set the configuration jumpers.
• Remove AC power from the computer before inserting the
card.
• Retain the ESD bag for handling the card.

The 3PCI2 Dual Port serial interface card is designed to work with
Windows based IBM compatible computers with a PCI bus. The card
is Plug and Play compatible which permits the Windows Operating
System and driver to set the addresses and IRQ used by the card.
If you are developing your own software, make sure that the
communications routines support Windows communication drivers
and a wide range of COM ports (Com1 to Com16 or higher).

Your 3PCI2 serial card was tested for proper operation before
packaging. It should be in perfect mechanical and electrical condition
upon receipt.
CAUTION:ELECTROSTATIC SENSITIVE DEVICE
Use ESD precautions for safe handling.
Before removing the card from the anti-static protective packaging:
• Discharge any static electricity buildup on your body by touching
a large grounded metal surface or the metal chassis on
equipment connected to earth ground by a 3-wire power cord.
• Avoid touching the gold connectors or other parts on the card
except as necessary to set the configuration jumpers.
• Remove AC power from the computer before inserting the card.
• Retain the ESD bag for handling the card.
• Save the packaging for storage or shipping.
Before Starting…
The card is normally pre-configured for RS-232 operation.
Check/Set 3 operating Mode/Jumpers for each port.
Device Driver Setting for RS-485 Mode:
After driver installation, set DTR Operation to RS-485 Mode.
See Chapter 4,

The 3PCI2 drivers are unique to this series of cards. If at some point
in the future, you want to update these drivers, remove these drivers
before installing the new version. See Removal at page 17.
Windows 98 screens are shown for this section. Windows 95 will
have other screen names and text shown. Windows Classic settings
used as standard.
1. Configure each port on card and install it – see Chapter 2.
2. Make sure PnP OS is set in the BIOS. Power up the computer.
3. Windows will detect the PCI card, start the Add New Hardware
Wizard, and begin driver installation
4. The driver installation goes through several steps after finding
the driver files. The first part installs the driver for the card, then
after Finish, the second part installs the serial driver each Com
port. Do not remove the disc until completed.
5. Click Next.

Another similar screen will be shown before the above, and after.
The second time the above is shown, installation will have
completed. Wait for the process to complete.
To verify the installation, open Start, Settings, Control Panel,
System.
Then select the Device Manager Tab.

From the Device Manager, Select Properties, Settings, Advanced.
Available names for Com numbers are shown. Select a new number
from those not “in use”. Com numbers from Com1 to Com256 may
be available. Com numbers “in use” may be used by motherboard
ports, modems, virtual com ports for network serial server devices or
FAX modem. Formerly installed USB to serial adaptors, PCI cards or
other hardware may have reserved a com number. The device may
need to be added back to the system, or the registry may need to be
edited with Reg. Edit or a similar utility.
