Before you begin...
You must set jumpers on your 16-bit card
before you attach it to your UltraSound.
These jumpers determine which Base
Address, DMA, and IRQ settings will be
used by the card.

Default Choices
Base Address 5
30 530,604,E80,F40
DMA 3 1.2*, 3
IRQ 5 3, 4, 5,6,7,9**

* DMA channel 2 is a possible setting for the jumpers; however, on ATs this channel is used for floppy disk
drives, so it is strongly recommended that you do not select it.

** Do not select IRQ 9 if another device is using IRQ 2 (IRQ 2 cascades to IRQ 9).
Refer to Figure 2 and the charts printed on the 16-bit card to see how to set the
jumpers for the available choices.

The defaults should work for most computer systems. However, if you have other
equipment in your computer which uses one of those settings, you will need to
change either the setting on the 16-bit card or on the conflicting equipment.

Note! To avoid conflicts, record all current addresses, IRQs (Interrupt Requests)
and DMAs (Direct Memory Access Channels) used by other adapter cards in
your system beforeyou install the 16-bit recording card.

The I/O Port Address on the 16-bit card MUST BE UNIQUE—not the same as
your UltraSound (or any other device in your system)
—or your card won't

A conflict may occur if you have a printer connected to LPT2 (Printer 2)
because LPT2 uses IRQ 5, the same IRQ as the 16-bit recording card uses by

The selections will be tested during the software installation after you have
installed the card. If the settings need to be changed, you will have to remove the
card and move the jumpers. It is recommended that you consider carefully any
possible conflicts with other equipment in your PC before doing the hardware

Recording at or near the maximum capacity of the 16-bit recording option (for ex-
ample, 16-bit stereo at 44.1 kHz) can strain the throughput capacity of many PC
systems. You may encounter a situation where you start recording in an applica-
tion, but cannot get the application to respond to your command to stop because
it is too busy keeping up with the recording. "Runaway" recordings like this can
occur with any sound card or software when high throughput recording is

If runaway recording occurs in Windows, you can stop it by pressing
<Ctrl>+<Alt>+<Del>. You will then be given the option to stop the application. In
any case, any time a recording ends abnormally, it is a good idea to run CHKDSK
on your disk.

You should be able to get reliable high-speed recordings without runaway if you
observe the following:

• Do not record to a disk that is using a compression scheme (such as
DoubleSpace). The disk compression algorithms slow down the transfer of

• Be sure that the disk you are recording to is not badly fragmented. Use a disk
defragmenting program such as DEFRAG, which comes with MS DOS v.6.0
and later.

« If you are still having problems, consider recording to a RAM disk. MS DOS
and Windows users can set up a RAM disk using the RAMDRIVE program
that comes with DOS.

installing the Option card
» Turn off your computer, but leave it plugged in so that grounding is still

• Ground yourself by touching your computer's case, or wear a grounding wrist
strap when handling the 16-bit card to avoid damage from static discharge.

» REMOVE your UltraSound card.
» With your fingers, remove the black, plastic clips from the four sets of jumpers
shown in Figure 1. Do not remove any other clips!

Important! Keep the jumper clips in a safe place in case you want to remove the
16-bit card later for any reason. If you do wish to remove the 16-bit card and use
the UltraSound without the daughter card, replace the jumper clips in the

positions shown in Figure 1._________________
Fig. 1 -Location of jumpers to be removed from the UltraSound
Note! If you don't remove these jumpers, it will not be possible to attach your 16-
bitcard to your UltraSound.

» If the jumpers remaining on your UltraSound are pull tab jumpers, fold over the
tabs, or cut them off, before installing your card.

» Turn over the card and firmly connect the P2 connector on the 16-bit card to
the Ultrasound's Jl connector (see Figure 2).

Make sure the pins are aligned. If the pins do not line up, try to insert the card
on an angle. Align the pins on the first row first, then press down. If the card
does not go on with firm pressure, do not force it. Look at the UltraSound board
to see whether a capacitor or other component is too close to one of the jumper
sockets. Gently bend any such components away from the connector.

Fig. 2 - The 16-bit card and connections
» Check that you've fully inserted all of the pins. The card should be snug against
the UltraSound card's external connector plate. The notched ends of the plastic
connector pegs must snap through the guide holes to the back of the
UltraSound board. If the connector pegs are difficult to snap through the guide
holes on the UltraSound, remove the 16-bit card, pull out the connector pegs,
and insert the opposite ends of the pegs into the 16-bit card. Then re-install.

» Reconnect the CD audio cable, if you have one, to GDI IN or CD2 IN on the 16-
bit card. You must use the CD connectors on the 16-bit card, NOT on the

* Re-insert your UltraSound card, with the daughter card attached, into your

Note! This installation guide covers adding the 16-bit card to your UltraSound.
See your UltraSound installation guide for instructions on installing the
card into your PC.

You may wish to leave the cover off of your computer until you have finished the
software setup, in case you need to change settings on the 16-bit card .

Be careful not to insert your UltraSound too close to another card in your
computer. If you have the slot space available, keep your UltraSound and 16-Bit
Recording Option one slot away from other cards.

Before you begin...
Please note that installation for both DOS and Windows software is done in DOS,
NOT Windows.

It's a good idea to make a working copy of your original disks. Use the copy to
install your software, and keep the originals in a safe place.

The software on the installation disks is compressed; during installation, it will be
decompressed to about 5 MB of disk space on your hard drive.

It's a good idea to disable any TSR (Terminate and Stay Resident) programs before
installing software.

During installation, the software will be copied into your UltraSound directory. We
recommend that you use the directory where your original UltraSound files reside.
The required configuration information will be added to your system's configura-
tion and start-up files automatically.

Getting Started
To install, please perform the following:
» Insert the 16-Bit Software Disk into your 3.5" disk drive A: or B:.
» From DOS:

Type: A:\INSTALL (OR B:\INSTALL) <enter>
Please follow the instructions on screen to install your UltraSound software.
Simply press <enter> to install all software onto your hard drive.

UltraSound Setup Program
The Setup program is a utility to help you choose the correct configuration
settings for your UltraSound card. Its purpose is to make it as easy as possible for
you to get Base Address, DMA and IRQ settings that work in your computer.

Printed in Canada 901-0056-00
Gravis defaults to the following jumper settings on the 16-bit recording card: Base
Port Address (J7 on your 16-bit card) is set to 530 Hex. IRQ (J2) is set to 5, and
DMA (Jl) is set to 3. If a conflict occurs (two devices using the same resource —
like DMA or IRQ), you have the option to set the jumpers yourself: remove the 16-
bit card and refer to the charts printed on the card for settings.

Note that the DMA and IRQ settings for the 16-bit card must be different from
those of the UltraSound.

The Setup program is run automatically when you do the install. If you need to
run it later for any reason:

» From the directory you installed the 16-bit software into, Type: SETUP <enter>.
If the setup program doesn't detect your 16-bit card (i.e., no 16-bit options are
shown in Setup):

• Make sure you have attached it properly to your UltraSound.
• Make sure the software is installed and running from the correct directory.
