Introduction

Welcome to the world of data communications. You have acquired one of the finest intelligent data/fax modems available today, the MultiModemZDX, from Multi-Tech Systems. This Owner’s Manual will help you install, configure, test and use your MultiModemZDX.

Requirements

In addition to the contents of the MultiModemZDX package, you will need the following equipment.

Computer

The MultiModemZDX (MT3334ZDX or MT3334ZDXV) can be connected to any computer with an RS-232 serial port, such as the IBM PC, XT, AT, and PS/2 computers, and most IBM compatibles. Note that your computer system should have a processing speed of at least 75 MHz in order to take full advantage of the telephony features of this product.

Serial Cable

You will need 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.

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.
