Protect Yourself from Electric Shock
To reduce the risk of electric shock:
n
Switch off the power and remove power cords
before opening the computer case to install the
D/41D or D/21D.
n
Do not re-attach power cords and switch on power
to the computer while the computer case 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
stat ic 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/41D or D/21D 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 board first in any
other operating system environment.
D/41D or D/21D Factory Defaults
You may be able to use the factory defaults when install-
ing the D/41D or D/21D board. Read through these
instructions and check for possible interrupt level (IRQ)
and memory address conflicts between the D/41D or
D/21D 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/41D or D/21D. Some voice software includes such a
software utility, or a separate board configuration utility,
to help with the D/41D or D/21D installation and
configuration.
Configuring the
Hardware
Configuring Multiple Voice Boards (JP7)
You can install up to 16 D/41D or D/21D boards in a
system. One and only one board in a system can have
the jumper on JP7 installed (see D/41D Physical
Description):
n
One board: Leave the jumper on JP7 installed
(default).
n
Multiple boards: Remove the jumper on JP7 from
all
but
one board.

Setting the Hardware Interrupt Level (JP1)
The default hardware interrupt level (IRQ) is IRQ 2/9;
IRQ 2 is used when the board is installed in an XT-type
PC and IRQ 9 is used with an AT-type PC.
Change the IRQ by moving the jumper on jumper block
JP1 (see Figure 2) to another IRQ setting if IRQ 2 or 9 is
in use by another device.
Note:
Set every D/41D and D/21D board in the system
to the same IRQ level.
Set the Memory Address
Each D/41D or D/21D and 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/41D
and D/21D 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
(see Figure 2) as follows:

Set the Offset Address (SW1:1, 2, 3)
The default offset address for the D/41D and D/21D is
0000H. Each D/41D and D/21D board in your system
requires a unique address, so you must change the offset
address on every additional D/41D and D/21D board. 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 map only one D/41D or D/21D
board to an offset, you can set multiple boards to
consecutive offsets within a base memory
segment as shown in the following example.
