Hardware Installation
Carefully read this chapter before installing the graphics card into
your system. Installing the card incorrectly may damage your com-
puter system, monitor, and the card.

Memory
The graphics card may come with 2MB or 4MB of SGRAM (Syn-
chronous Graphics RAM). A 2MB graphics card is installed with two
256Kx32 SGRAMs at locations U2 and U6, while a 4MB graphics
card is installed with four 256Kx32 SGRAMs at locations U2, U3,
U6 and U7.
PAL/NTSC TV System
The graphics card supports NTSC or PAL TV system. Please refer
to the label on the card to determine whether your graphics card
supports NTSC or PAL TV system. AGP-9800/N supports NTSC
TV system. AGP-9800/P supports PAL TV system.
Connecting a TV to the Graphics Card
The graphics card supports CVBS (Composite Video Broadcasting
System) and S-Video (Separate Video), also called Y/C (Luminance/
Chrominance). CVBS is a video stream that combines all of the pieces
required for displaying an image into one signal. S-Video (Y/C) is used
in a decoder to pull the luminance and chrominance apart in an NTSC
or PAL system.
Generally your TV is equipped with a Video In connector that
receives CVBS signal. Connect one end of the RCA-type video
cable to the RCA-type (Video Out) connector (J4) of the graphics
card and the other end to the Video In connector of your TV.
If your TV is equipped with an S-Video In connector (Y/C signal),
we recommend that you use this connector because Y/C signal
provides better resolution than CVBS. To transmit Y/C signal, connect
one end of a video cable to the S-video (7-pin DIN S-video Out)
connector (J3) of the graphics card and the other end to the S-
Video In connector of your TV.
Note:
The graphics card allows you to connect a monitor or TV. If a
monitor and TV are connected at the same time, only the monitor
will work.

Installing a VMI Card onto the Graphics Card
The graphics card supports a VMI (Video Module Interface) inter-
face. This interface is used for connecting a video module, such as
a MPEG module, to a “Video Ready” GUI device.
1.Position the VMI card by aligning the connectors on the card
to J1 and J2 of the graphics card.
2.Make sure pin 1 of the connectors on the VMI card is aligned
with pin 1 of J1 and J2 on the graphics card.
3.Press both sides of the VMI card firmly onto the graphics card.
Make sure the VMI card is seated properly.
Installing the Graphics Card
For most computer systems, you will only need a medium size
Phillips screwdriver to remove the cover and a small flat-blade
screwdriver to secure the monitor cable.
Warning:
Electrostatic discharge (ESD) can damage your graphics card,
system board, processor, disk drives, add-in boards, and other
components. Perform the upgrade instruction procedures
described at an ESD workstation only. If such a station is not
available, you can provide some ESD protection by wearing an
antistatic wrist strap and attaching it to a metal part of the
system chassis. If a wrist strap is unavailable, establish and
maintain contact with the system chassis throughout any
procedures requiring ESD protection.
Handling the Graphics Card
It is quite easy to inadvertently damage your graphics card even
before installing it in your system unit. Electrostatic discharge can
damage computer components without causing any signs of physical
damage. You must take extra care in handling the graphics card to
ensure that no static build-up is present.

HardwareInstallation
Tips in Handling the Graphics Card
1.To prevent electrostatic build-up, leave the graphics card in its
anti-static bag until you are ready to install it.
2.Do all preparation work on a static-free surface with graphics
card components facing up.
3.Hold the graphics card by its edges only. Be careful not to touch
any of the components, contacts or connections, especially gold
contacts, on the board.
Step 1: Switch Off Your Computer’s Power
Make sure that your computer is switched off and unplugged before
removing the cover. Also turn off any devices (printer, display, mo-
dem, etc.) you may have attached to your computer.
Warning:
Hazardous voltages are present and exposed when operating
the computer with the cover removed. To prevent equipment
damage and personal injury, never apply power to the com-
puter when the cover is off.
Step 2: Remove Your Computer’s Cover
Refer to your computer system manual for specific instructions on
removing your computer’s system unit cover. In general, you will need
to remove several screws on the back or side of the system unit and
then slide the cover off.
Step 3: Remove the Slot Cover
Remove the screw and slot cover at the back of the AGP slot. Save
the slot cover for future use. You will be using the screw in a future
step.
Step 4: Unpack the Graphics Card
Remove the graphics card from the shipping carton and its protective
packing. Please do not throw away the packing material or the shipping
box. You may use these again to prevent damage should you need to
ship the graphics card for repairs.

AGP-9800GraphicsCardUser’sManual
Step 5: Insert the Graphics Card
Carefully slide the graphics card into the AGP slot. When the card’s
edge-connector is aligned with the slot on the system board, press
firmly on the top of the card to seat it. Make sure the graphics card
is straight and level compared to the computer’s system board by
viewing it from the side.
Once you are satisified with its alignment, insert the slot-cover screw
on top of the bracket at the back of the graphics card.
Step 6: Replace the Computer’s Cover
When you have finished installing the graphics card, put the cover back
on your computer's system unit. Refer to your computer's system
manual for instructions if necessary.
Step 7: Connect the Monitor or TV
The graphics card can only be used with an analog video display using
a 15-pin D-shell cable connector (standard VGA monitor connection).
If your monitor supports analog video but does not have a 15-pin
D-shell connector, see your monitor dealer for the adapter or optional
cable. After you plug the monitor cable into the VGA connector of the
graphics card, gently tighten the cable screws to hold the connector in
place.
Note:
Some monitors have a switch that chooses between analog and
TTL (or digital) operation. If your monitor has such a switch, set
it for analog.
To plug a TV to the graphics card, please refer to the “Connecting
a TV to the Graphics Card” section in this chapter of the manual.
Note:
If a monitor and TV are connected at the same time, only the
monitor will work.
