Chapter 1 - Introduction and Description
7
Network managers have the option of starting with the basic four modem configuration (model #ISI334/4), and then
adding four more modems at a later date without having to use another PC expansion slot.
This is accomplished b pairing one MultiModemISI with an auxiliar module (model #ISI3334/EC) interfacing both
with on-board connectors.
Some MultiModemISI on-board components include one jumper block for activating the number of ports in
increments of 4 or 8. One bank of 8 DIP-Switches for I/O address selection and one IRQ jumper block, that control
both the MultiModemISI and auxiliar module I/O addressing and IRQ values.
When installing a single MultiModemISI in our PC, the installation scripts create 8 devices. The first 4 devices are
active, however, the 4 devices on the auxiliar module are not active until connected to the MultiModemISI.

Hardware Installation Summary
This section provides ou with procedures for installing the MultiModemISI card(s) in our ISA or EISA bus personal
computer (or compatible with 16 bit ISA slot).
Hardware installation involves:
1) Opening our PC.
2) Setting card configuration (determining I/O address DIP-Switch setting and IRQ jumper setting).
3) Installing the card into the PC.
Determining Current System Settings
When ou install a device into our computer, the processor must have a means of routing information to and from
the device and the device must have a means of gaining the processor's attention. These are called Input/Output (I/
O) addresses and Interrupt Requests (IRQs), respectivel . The MultiModemISI card requires 16 I/O addresses and
one IRQ value which are not used b an other device in our s stem. When selecting a unique base I/O address,
be sure that the next address is also unused. You can install up to four MultiModemISI cards into our s stem.
Each card is shipped with its IRQ set at level 10 and a base I/O address of 210 hex. Check our s stems device
settings to see if these values can be used. If the defaults are alread in use, select a unique IRQ and I/O address
and record those values for the hardware and software installation sections that follow. For more information on I/O
addressing, see Appendix E.
Note If ou choose IRQ 3 or 4, ou ma have to disable a COM device from our BIOS setup. Also, most 386 or
higher compatible computers will not be able to assign IRQ2 to the MultiModemISI card because IRQ2 is used for
slave interrupt control.
Hardware Installation Procedure
Perform the following procedures to install the MultiModemISI card(s) into our PC-ISA bus computer. Installation
procedures include setting the I/O address switch block and the IRQ jumper. If ou have selected the default values
of: I/O Address 210 Hex and IRQ 10, certain steps ma be unecessar . However, if ou are installing multiple
cards, step 4a of the following procedure describes how to configure our card(s).

Chapter - Installation

Installation Procedure
Step Procedure
1 Make sure our computer and an peripheral equipment connected to it are turned off. Failure to do so ma
damage both our ISI card(s) and our PC. The MultiModemISI ma be installed in a PC-AT, 386, 486, or
Pentium equivalent ISA or EISA bus computer.
2 Remove the cover of our computer as instructed in our computers documentation.
3 Locate the unused slot(s) which ou will be using for our MultiModemISI card(s), and remove the slot cover(s)
per the instructions in our computers documentation.
4 Check the settings of the I/O address switch and the IRQ jumper to ensure that the are set properl for our
installation.
Note One MultiModemISI can be paired with an auxiliar module (model #ISI3334/EC) when it interfaces with
on-board connectors attaching both cards; effectivel providing 8 modem functionalit . For details on this
process, see Appendix F.
4a The default setting for the MultiModemISIs base I/O address is 210 hex. The default value for the IRQ jumper is
IRQ 10. Choose the IRQ value b covering the appropriate pins with the shorting plug (supplied). If our s stem
requires a different setting or if ou are installing multiple cards, refer to Appendix E for a table of valid address
settings.
5 Install the MultiModemISI card(s) into the selected expansion slot(s) in the same manner as an other add-on
card, as instructed in our computers documentation.
6 Fasten the retaining bracket to the computer chassis and replace the cover.
7 Your MultiModemISI card(s) requires a modular LINE JACK. This is t picall an RJ11C or RJ11W jack, but
could also be an RJ12 or RJ13 jack. To connect the modem(s) to the PSTN line(s), plug one end of the RJ11
cable(s) that is provided with the modem into the LINE JACK connector(s) and the other end into the phone-
compan -provided RJ11C or RJ11W modular phone jack(s).

card according to the PC manufacturer's instructions. Observe standard precautions regarding electro-static discharge
(ESD) when handling the ISI3334 board (the board should be kept in its shipping bag until used). During installation
handle the ISI3334 circuit card by its edges and keep one hand in contact with the PC chassis.
Set the Base I/O Address and the Interrupt Request (IRQ) values per the table below:
Recommended Base I/O Address and IRQ Values
ISI3334 Base I/O Address IRQ
Initial 8 port board 210h 10
First 8 port upgrade 220h 11
Second 8 port upgrade 230h 12
Third 8 port upgrade 240h 15
The I/O Address DIP Switch and the IRQ Jumper Block are located in the corner of the card that lies diagonally across from
the ISA bus.
3. Turn on the PC and start Windows 95/98.
4. Insert the ISI driver CD-ROM into the CD-ROM drive. (In some cases drivers may be downloaded from the MultiTech
web site and saved onto diskette. If so insert diskette into floppy drive now.)
5. (Follow either 5A or 5B but not both.)
A. From Windows Explorer open the 95-98 directory on the CD-ROM or floppy drive that contains the ISI driver file.
Highlight the file setup.exe.
B. From the Start menu go to Run. Browse to the path of the 95-98 directory.
