2. Installing The Audio Plus 3200
Please follow the instructions in this chapter describing the installation of
the Audio Plus 3200 and its bundled software. Your computer system may be
built differently and you should refer to its user's reference manual.
Note: Please read the "README" file, for the latest information concerning
the Audio Plus 3200 which was not available at printing time. To read the
file, type:
README
2.1. Plugging in the Audio Plus 3200
The steps provided below describe the procedure for a typical system. Your
system may differ.
1)Turn off your computer system, unplug the power cord and
remove the top cover.
2) Plug the the Audio Plus 3200 into any free slot of the computer.
3)Connect the Audio Plus 3200 to stereo speakers or headphones
directly (Refer to Chapter 3).
4) Due to difference in speaker power, set the volume control of the
Audio Plus 3200 to mid-range.
5) Replace the top cover and switch on the power.
2.2. Testing the Card
After installing the Audio Plus 3200 in your PC, boot the machine and put
the Audio Plus 3200 disk #1 into Drive A and type :
A: TESTSC
The TESTSC software is meant for testing the hardware configuration and
functionality of the Audio Plus 3200, including the required settings of the
I/O address, interrupt and DMA channels.
Vili

After you type [A: TESTSC], the following screen shows:
This program tests various features of the Sound Card.
It detects the base I/O port address and the available
IRQ line and DMA channel you may use.
The default values on IRQ and DMA settings should work fine with
most users. However, if you encountered a conflict prolem in
IRQ or DMA setting, please refer to the manual.
Press [ENTER] to continue
At the end of the test, you should be able to hear music playing and a voice
talking from your external speakers. This software test will ensure that
your the Audio Plus 3200 is properly installed.
If this test fails, please refer to the troubleshooting section. If you can not
find the problem, please contact your dealer.
2.3. Installation - Selecting Interrupt Lines
The IRQ and DMA settings are adjusted by software - no hardware changes
are needed. After you have installed the card, all you need to do is to run
this software. Do so by tying the following line:
A:\install
This will automatically run the software CONFIG.EXE. Once you enter
this software, it will be easy to follow the directions necessary. The
software will automatically choose the default IRQ and DMA settings and
change your CONFIG.SYS file for you. In this way these values will be
loaded for the Audio Plus 3200 each time you boot up your computer. The
line added to your CONFIG.SYS file will be:
DEVICE=C:\SOUND\SOUND.SYS /I:i /D:d /MIRQ:i /G:0
/CDT:G /CDP:340 /SSP:530 /M:330
Where: /I:i specifies the IRQ to be used, and i can be 7, 9, 10, 11 or 5.
/D:d specifies the DMA channel, and d can be 0, 1 or 3.
/MIRQ:i specifies the MPU-401 IRQ to be used, and i can be 5,
9 or 0 -- disable.

This installation software has been designed for ease of use. It is very rare
that you will encounter a hardware conflict. Therefore, after running this
software, you should be ready to use the Audio Plus 3200, without having
to worry about these settings. However, future hardware changes may
create conflicts. The following two sections explain more about this
situation. Even if you have no problems, you can still look them over for
your information.
2.3.1 Future Hardware Changes
If, in the future, you add a new card and there is a conflict between the
Audio Plus 3200 and another card, you can use the CONFIG.EXE
(described in detail in Chapter 4) to change the IRQ and DMA settings of
the Audio Plus 3200. Remember that if you do change the IRQ and DMA
settings, you will need to reboot your computer for the changes to take effect.
2.3.2, What are IRQ's and DMA's?
If you have made changes to your hardware, are having problems with first-
time installation, or are just curious, we have provided a brief explanation
below of the ways in which computer hardware can have conflicts.
Computers use signal lines, or channels to allow devices to communicate
with the main processor. If two devices try to use the same channel to
communicate with the CPU or processor, there will be a conflict. There are
three kinds of signal lines: :
1. IRQ or interrupt lines are used when a device notifies the central
processor that information needs to be sent or received.
2. DMA or direct memory access channels are used to transfer data to
memory (as opposed to transferring information to the processor).
3. I/O or input/output addresses signify the type of channel that is used
to transfer data between devices and the central processor.
When you first install the card into your system, you will use the program
INSTALL.EXE to set the IRQ and DMA settings. This program will make
sure there are no conflicts. However, adding cards in the future may cause
conflicts if any one of the above three conflict with another card. In this
case, as mentioned above, you will need to run the CONFIG.EXE software
to change the settings (unless you change the settings of the new adapter card).

2.4. Problems Encountered When Installing The Audio
Plus 3200
This section will help you if you have already followed the instructions in
the installation guide and are still unable to solve your problem. You are
probably encountering a problem due to a conflict between various
hardware. When installing the Audio Plus 3200, there could be some
possible hardware conflicts with other adapter Cards.
The Audio Plus 3200 uses:
1)DMA channel 1 as the default channel. Selectable
channels: 0,1 and 3.
2) Interrupt default at IRQ 7 (used for voice/MIDI operations)
Selectable channels : IRQ5, IRQ7, IRQ9, IRQ10 and
IRQ11.
3)I/O address : 220H - 23FH as default
Switch may select at 220H or 240H. FM music chip also
uses addresses 388H, 389H, 38AH and 38BH. The joystick
port uses the standard address of 200-207H.
1) DMA Conflict
The Audio Plus 3200 is default set to DMA channel | in order to maintain
compatibility with other sound cards. If the playback of digitized sound is
not functioning, please ensure no other hardware devices in your system
use DMA channel | at the same time.
The DMA channel used by the Audio Plus 3200 can be shared with other
adapter cards, provided that these cards can share their DMA channel.
Alternatively, other cards using DMA could have their DMA channels
selectable. In such cases, the DMA Channel on the other card should be
moved to either Channel 0 or Channel 3. If this is not possible, use the
CONFIG.EXE software to change the DMA and IRQ settings of the Audio
Plus 3200.
2) Interrupt Line (IRQ) Conflict
The Audio Plus 3200 uses interrupt line IRQ7 as the default setting. If an
interrupt conflict occurs, you can change the interrupt of the Audio Plus
3200 to IRQS, IRQY, IRQIO or IRQI1. See the table on the following page
for the best IRQ line to use.

3) I/O Address Conflict
If there is a conflict with another card in your system, we suggest you
change the I/O port address of the other card. Remember to re-install the
I/O port address for programs running on that card.
The possibility of conflict on the default I/O address of 220H is very small.
We advise against changing this I/O port address. Changing from this
default I/O address would mean that you have to re-install many software
programs that support the Audio Plus 3200.
If you are using the MPU-401 mode and the I/O address is 330, a conflict
may arise with some popular SCSI adapters.

3.4. MIDI Device (Keyboard) Connection
To play back or record the MIDI file with the MIDI device like keyboard, you
can connect the MIDI cable into the MIDI port on the Audio Plus 3200.
3.4.1. MIDI Port and MIDI Cable
To connect the Audio Plus 3200 to a MIDI keyboard (or synthesizer), you
need to plug the optional MIDI cable to the joystick/MIDI port. This MIDI
cable is required because the standard MIDI IN/OUT plugs don't match the
computer interface connectors.
This MIDI cable provides MIDI-IN and MIDI-OUT connectors and one
joystick port. You will not lose the joystick port as it is replicated on this
MIDI Cable. Connect the MIDI-IN connector to the MIDI output socket on
the MIDI keyboard, connect the MIDI-OUT connector to the MIDI input
socket on MIDI keyboard.
A MIDI cable and MIDI keyboard do not complete the list of what is
needed for a MIDI setup. You still need the software designed for MIDI.
You can use either MPU-401 or Sound Blaster compatible MIDI software.
MPU-401 is a popular adapter for the P.C. It is supported by many MIDI
software packages.
3.4.2. MIDI Port Connector
The MIDI connector is a 15 pin D-Type connector. The MIDI port share
the connector with game input device, it is usually joystick, so you need a
special MIDI cable to connect the Audio Plus 3200 and MIDI device.
XiV

The MIDI connection use three pins of the connector: MIDI receive, MIDI
transmit and the signal ground. For details, please refer the MIDI pin
connector definition.

3.5. Joystick Connection
The joystick port on the Audio Plus 3200 uses an analog joystick with a 15-
pin D-Sub connector. It is identical to that on the standard PC Game I/O
port and supports any software that uses the standard PC joystick.
This 15-pin connector also serves as the MIDI interface of the Audio Plus
3200. With the joystick port replicated on the optional MIDI BOX, both
the MIDI device and joystick can share one slot leaving more room on your
PC for other peripheral cards.
3.5.1. Using More Than One Joystick
If you need to run two joysticks from the Audio Plus 3200 Joystick Port, a
Joystick Y-Cable is separately available. This Y-Cable separates these 2
joystick pins into 2 connectors for joystick connection.
3.6. CD-ROM Drive Connection
3.6.1. CD Audio-In Connector
The Audio Plus 3200's specially designed, high fidelity audio mixer ties
together all the sounds it can tap: CD-audio, sequenced MIDI synthesizers,
digitally sampled audio samples, external audio -- and plays them through
whatever playback system you want. Then you can mix all of your sound
sources and play them together.
The Audio Plus 3200 can also use CD ROM without extra speakers. Using
the internal cable, you can connect the CD ROM Audio to the CD Audio-In
XV

connector directly. The Audio Plus 3200 mixes the sound input from CD
Audio-in with other music/sound and outputs from it's speaker.

AT-BUS CD-ROM drive interfaces. It also support the E/IDE CD-ROM
drive.
Please notice the direction of the cable. Pin 1 of the Audio Plus 3200
connector must be attached with pin | of the cable. Pin | is marked on the
Audio Plus 3200, and is easily found. Pin | of the cable is usually colored
with red. Please notice the position of pin 1 Sony Connector is up side
down. However, it is best to refer to the installation manual for your CD-
ROM drive or contact your dealer for the exact position of pin 1. Please
also refer to Chapter 4, "CONFIG.EXE" and "CDSETUP.EXE".
3.6.3. Installing a CD-ROM Driver
The CD-ROM driver comes with the CD-ROM drive. Please refer to the
installation procedure described in the user's manual of the CD-ROM drive.
Two programs are usually needed to make a CD-ROM drive work properly.
One is a CD-ROM hardware driver. The other is MSCDEX.EXE. Please
make sure you have loaded the hardware driver and MSCDEX.EXE before
you start using the CD-ROM drive.
3.7. PC Speaker Connection
The Audio Plus 3200 allows the sound of Audio Plus 3200 to be redirected
to PC internal speaker. The installation procedure is:
XVi
