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

Protect Yourself from Electric Shock

To reduce the risk of electric shock:

nSwitch off the power and remove power cords before opening the PC cover to install the D/41H or D/21H.

nDo 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:

nWear a grounded, static-dissipative wrist-strap for the entire hardware installation.

nKeep the board in its anti-static container when it is not being handled.

nWork at a static-safe work area (see Figure 1).

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):

nOne board: Leave the jumper on JP7 installed (default).

nMultiple 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:

*Base memory address segment B000H does not support offset address settings 0000H – 6000H.

nWhile 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.
