Model MT5600ZDX

Introduction

Welcome to the world of data communications. You have acquired one

of the finest intelligent data/fax modems available today, the MultiMo-

demZDX, from Multi-Tech Systems. This Owners Manual will help you

install, configure, test and use your MultiModemZDX.

Product Description

Your MultiModemZDX incorporates new modem technologies called V.90

and K56flexTM, that enable Internet connections at data rates up to 56K bps

over standard telephone lines. This 56K technology is able to propel data

downstream from the Internet to your computer at speeds of up to 56K bps

because data is digitally encoded instead of modulated. Upstream

transmission, mostly keystroke and mouse commands from your computer

to the central site, continue to flow at the conventional data rate of 33.6K

bps.

Your MultiModemZDX offers interactive automatic dialing, as well as

command mode option configuration. You may store four command line/

telephone numbers, of up to 40 characters each, in the modems

nonvolatile memory. The modem pulse or tone dials, and recognizes dial

tones and busy signals for reliable call-progress detection. Themodem

can detect AT&T calling card tones. It is FCC-Registered for connection to

telephone networks without any Data Access Arrangements (DAAs).

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.

The MultiModemZDX is a desktop fax/modem for compatible IBM Personal

Computers; and provides dial-up asynchronous communication capability

with other personal computers, terminals, on-line computer services or

other types of computer systems.

Connection to the phone line and/or an attached telephone device is made

by RJ11 modular type connectors; the PC connection is made via an

RS232C/V.24 serial cable receptacle; and low voltage DC power is supplied

to the MultiModemZDX through a modular power supply connection

included with the modem. All these connections are located on the rear

of the MultiModemZDX. Hardware installation procedures are described in

Chapter 2.

Owners Manual

General features include:

4Compliance with major ITU-T, TIA, and EIA international standards to

ensure compatibility with other modems.

4Distinguishes data, and fax calls.

4Caller ID to identify your callers phone number (available on U.S.

products).

Data

while maintaining compatibility with lower-speed modems.

Note the V.90 and K56flex standards asymmetrically transfers data--

client downloads at speeds up to 56K bps, client uploads at speeds up

to 33.6K bps.

4Supports the enhanced ITU-T V.34 standard, with data transmission

speeds to 33.6K bps, while also maintaining compatibility with lower-

speed modems.

4Supports V.90 and K56flex speeds plus 33.6K, 31.2K, 28.8K, 26.4K,

and 0-300 bps.

4Automatic fallback to slower speeds in noisy line conditions, and fall-

forward to faster speeds as conditions improve (line quality monitoring).

4ITU V.42 LAP-M and MNP Class 3 and 4 error correction.

4ITU V.42bis (4-to-1) and MNP 5 (2-to-1) data compression.

4MNP10 and MNP10ECTM Enhanced Cellular Performance (error correc-

tion).

4H.324 compliant (videophone ready).

4Automatic disabling of compression when transferring already-com-

pressed files.

4Autodial, redial, pulse (rotary) and touch-tone dial.

4Dial tone and busy signal detection for reliable call-progress detection.

4Distinctive ring support to route voice, data, or fax calls on a single

phone line.

4Plug and Play (PnP) serial support.

4FlashROM upgradable.

4Compatibility with the standard AT command set used by most commu-

nication programs.

Model MT5600ZDX

Fax

4Supports V.17, Class 1and Class 2 Group 3 fax communication

standards, allowing it to communicate with other fax modems as well

as with fax machines.

4Sends and receives faxes from your computer at 14,400 bps, 9600 bps,

7200 bps, 4800 bps, 2400 bps, or 300 bps.

What Is in Your Modem Package?

Installation

In addition to the contents of the MultiModemZDX package, you will

need the following equipment.

Computer

The MultiModemZDX can be connected to any computer with an RS-232

serial port.

Owners Manual

Serial Cable

You must provide a serial cable to connect the MultiModemZDX to your

computer. Serial cables are available at computer stores and many office

supply stores. The cable must have a DB-25P connector at the modem end.

For IBM and compatible computers, the other end may have a DB-25P

connector or a DB-9S connector, depending on your particular computer

and whether you are using the COM1 or the COM2 serial port. The FCC

requires cables to be shielded.

DB-25 DB-9

Telephone Line

You must have a telephone line with a conveniently located connector

(jack) to accept the cable that comes with the MultiModemZDX. If you

do not have a telephone jack near your computer, you should install an

extension before proceeding.

In North America, telephone extension kits and accessories are available

at electronics stores and wherever telephones are sold. You may also hire

an independent contractor or your local telephone company to do the

work. If you want to add a line for your MultiModemZDX fax modem,

you must contact your telephone company.

Model MT5600ZDX

Safety Warnings

1. Never install telephone wiring during a lightning storm.

2. Never install telephone jacks in wet locations unless the jack is specifically

designed for wet locations.

3. Never touch uninsulated telephone wires or terminals unless the telephone

line has been disconnected at the network interface.

4. Use caution when installing or modifying telephone lines.

5. Avoid using a telephone (other than a cordless type) during an electrical

storm. There may be a remote risk of electrical shock from lightning.

6. Do not use the telephone to report a gas leak in the vicinity of the leak.

Communications Software

To operate the ZDX, you must have data and fax communications software.

Data comm software simplifies control of the modem by guiding you through

the process of selecting your serial port, your port speed, and other variables,

and then storing your settings, including frequently called phone numbers,

so they can be recalled with the stroke of a key or the click of a mouse. The

software must be set up, or configured, before you can use it. You must have

Microsoft Windows 3.1 or later to run most prevalent software packages. If

you require software for DOS or for the Macintosh operating systems, please

contact Multi-Tech Sales.

Assemble the Modem

The only assembly required is to mount the feet on the bottom of the modem.

Simply peel the four self-adhesive plastic feet off the backing strip and press

them into the recesses on the bottom of the modem. Alternately, or

additionally, you can use the self-adhesive Velcro patches to mount the

modem to a vertical surface or to keep it from being dislodged on a horizontal

surface.

If you use the Velcro patches, we recommend that you mount them where

they will not obscure the labels on the bottom of the modem. The ZDX has

no special placement restrictions, but we recommend that you place it where

you can see the indicators on the front panel.
