1 Introduction
Chapter 1 - Introduction
Congratulations on your purchase of the MultiModem® ZPX. You have acquired one of the finest internal
data/fax modems available today from one of the world’s oldest modem manufacturers: Multi-Tech
Systems, Inc. This User Guide will help you to install, configure, test, and use your modem.
One Modem, Worldwide Use. The MultiModemZPX is designed for global applications. This means one
modem can ship around the world. The global modem is ideal for businesses with global operations that
want to standardize on one modem and are looking to simplify the ordering process. Go to
www.multitech.com/ to see a complete list of all the countries for which this modem has approvals.
Product Description
The MultiModemZPX provides high-speed data transfer and fax capabilities for small businesses,
telecommuters, and SOHO users. Its supports the new ITU-T V.92 protocol which provides quick
connections, downstream transmissions at speeds up to 56K bps*, and upstream transmissions at
speeds up to 48K bps when connected to V.92-compatible Internet service providers. Transmissions
between the MultiModemZPX and other client modems are limited to 33.6K bps, as are upstream
transmissions to non-V.92-compatible ISPs and downstream transmissions that are converted more than
once on the telephone network.
Fax Communications: The MultiModemZPX also supports “Super G3” ITU-T V.34 fax communications at
speeds up to 33.6K bps with Class 2.1 fax commands.
Features: Modem features include remote configuration. In standard mode, you can store up to four
command lines or telephone numbers of up to 40 characters each in the modems’ nonvolatile memory.
Other modem capabilities include AT&T calling card tone detection, pulse and tone dialing, adaptive
answer, V.42 error correction, and V.42bis and V.44 data compression.
NOTE:
* Though this modem is capable of 56K bps download performance, line impairments, public telephone
infrastructure, and other external technological factors currently prevent maximum 56K bps
connections.

Step 2 - Configure Jumpers
The MT5634ZPX board contains seven Berg jumpers for setting the interrupt request (IRQ) number and
COM port assignment. The jumpers are located on the lower part of the PC board as shown below. The
IRQ number is set using jumpers 1, 2, and 3 and the COM port assignment is set using jumpers 4
through 7. The default IRQ number is IRQ5 and the default COM port assignment is COM4.

PC Board Jumpers
1. Before handling the MT5634ZPX, discharge static in your body by touching a metal piece of
the computer chassis. Carefully remove the MultiModemZPX from its antistatic bag, handling
it only by the mounting bracket and edges. Do not touch the gold-plated connectors along the
bottom edge.
2. To change the IRQ from the default IRQ5, move the berg jumper from the default position to
your new position that supports your application.
3. To change the COM port assignment from the default COM4, move the two berg jumpers from
their default positions to your new positions that supports your application.
Step 3 - Install the Modem into Your Computer
Installing the MultiModemZPX requires you to open your computer. Please consult your computer manual
in addition to the following instructions:
1. Turn off the computer and unplug it. Failure to do so may result in damage to both the
MultiModemZPX and the computer. Do not turn on the computer until the instructions tell you
to do so.
2. Remove the cover from the computer as instructed in the computer manual.
3. Select an empty ISA expansion slot. Remove the expansion slot cover and save the retaining
screw.
4. Place the MultiModemZPX directly above the expansion slot and gently, but firmly, push it into
the connector until the card’s retaining bracket is flush against the computer chassis.
5. Fasten the retaining bracket to the computer chassis with the screw saved in step 3.
6. Replace the cover of the computer.
