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

RJ-14 Connectors for interface with PBX or CO lines

Jumper block to set interrupt level

Jumper to set base memory segment

Jumper to enable hardware interrupt circuitry

Jumper to select the built -in loop start interface or an external interface (DTI/124 T -1 card)

Jumpers to set ring detection threshold

Connector for Analog Expansion Bus (AEB)

Switch to set the offset address and default line state

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:

Offset	SW1:1, 2, 3
Address	Top Edge	— SW1: Switches —
(Hex)	View	1	2	3

Protect Yourself from Electric Shock

To reduce the risk of electric shock:

nSwitch off the power and remove power cords before opening the computer case to install the D/41D or D/21D.

nDo 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:

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/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

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):

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

nMultiple 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:

Base Address	JP6 / JP5
(Hex)	Top Edge View	JP6	JP5
D000		removed	removed
(default)
A000 †		removed	installed
B000 †		installed	installed
C000 ‡		installed	removed

nWhile 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.

1	D000:0000	1–4
