Protect Yourself from Electric Shock
To reduce the risk of electric shock:
n
Switch off the power and remove power cords
before opening the PC cover to install the D/41H or
D/21H.
n
Do not re-attach power cords and switch on power
to the computer while the PC cover is removed.
Protect the Board from Static Electricity
Computer boards are static-sensitive and can be damaged
by touching or handling them. To prevent damage from
static electricity, do the following:
n
Wear a grounded, static-dissipative wrist-strap for
the entire hardware installation.
n
Keep the board in its anti-static container when it is
not being handled.
n
Work at a static-safe work area (see Figure 1).

Static-safe work area
A static-safe work area consists of a grounded static-
dissipative wrist strap and a work surface covered with
or composed of a grounded static-dissipative material.
The work surface drains electrical charges from conduc-
tive materials when the materials are placed on the sur-
face. The grounded static-dissipative wrist strap drains
static charge from the person wearing the strap. Both
components ensure that static charges are drained at a
rate and current level that are safe. Both must be used
any time a person is handling any component.
Read Your Software Documentation
Your application software or Dialogic software release
(hereinafter collectively called “
voice software
”) may
have special installation or configuration instructions or
requirements. Be sure to read all software documentation
for any such instructions or requirements.
Installation Order
You can install the D/41H or D/21H and voice software
in any order, but Dialogic recommends that you install
the voice software first when running in a Windows
95
or Windows NT
environment, and the board first in
any other operating system environment.
D/41H or D/21H Factory Defaults
You may be able to use the factory defaults when install-
ing the D/41H or D/21H board. Read through these
instructions and check for possible hardware interrupt
level (IRQ) and memory address conflicts between the
D/41H or D/21H board and other software or hardware
devices (for example, video card or CD ROM controller
card) before installing the board.
Note:
If you own a software utility that can determine
what IRQs and memory addresses are in use, run it to
help determine potential conflicts before installing the
D/41H or D/21H. Some voice software includes such a
software utility, or a separate board configuration utility,
to help with the D/41H or D/21H installation and
configuration.
Configuring the Hardware
Installing More Than One Voice Board (JP7)
You can install up to 16 D/41H or D/21H boards in a
system. One and only one board in a system can have
the jumper on JP7 installed (see Figure 2):
n
One board: Leave the jumper on JP7 installed
(default).
n
Multiple boards: Remove the jumper on JP7 from
all
but
one board.

Set the Hardware Interrupt Level (JP1)
The default hardware interrupt level setting (IRQ) is
IRQ 9 (a jumper on JP1 pins labeled IRQ 2/9 as shown
in Figure 2). Change the IRQ by moving the jumper on
JP1 to another IRQ setting if IRQ 9 is already in use.
Notes: 1)
Set every D/41H, D/21H and compatible
board in the system to the same IRQ level.
2)
Although the pins for IRQ 9 are labeled
IRQ 2/9, IRQ 2 is
not
available for this board.
Set the Memory Address
Each D/41H, D/21H or compatible voice board installed
in a computer must have a unique memory address
consisting of a base memory address segment and an
offset address.
Set the Base Memory Address
Segment (JP5 and JP6)
The default base memory address segment for the D/41H
and D/21H is D000H (Hexadecimal). Generally, you
should use the default unless there are more than eight
boards in your system or if other non-Dialogic devices in
your system must use the D000H segment. Select the
base address memory segment with jumpers JP5 and JP6
as follows:

Set the Offset Address (SW 1: 1, 2, 3)
The default offset address for the D/41H and D/21H is
0000H. If you need to change an offset address, set the
switches 1, 2, and 3 on SW1 (see Figure 2) as follows:

While you can set only one D/41H or D/21H board
to an offset, you can set multiple boards to consecu-
tive offsets within a base memory segment as shown
in the following example.
