Desktop data and fax modem

The Multi-Tech MT3334ZDX is a desktop data and fax modem built for PCs that still rely on a serial connection. It handles dial-up data at up to 33.6 kbps and fax transmission at up to 14.4 kbps using ITU-T V.34, V.32bis, V.32 and V.22bis modulation standards.

Serial host interface and phone line ports

The unit connects to the host via a serial interface and presents one RJ-11 modem port plus one RJ-11 phone line port on the rear. Its desktop form factor measures 5.7 inches wide, 4.3 inches deep and 1 inch high, so it sits on a shelf or desk without occupying a drive bay or expansion slot.

Class 1 and Class 2 fax support with long warranty

Bundled fax support covers both Class 1 and Class 2 operation, letting standard communications software send and receive faxes without extra drivers. The modem ships in retail packaging and carries a ten-year limited warranty from the manufacturer.

Questions about this item

What is the maximum data rate the MT3334ZDX can sustain over its serial link?

The modem tops out at 33.6 kbit/s for data, and the serial port must run fast enough to keep pace with that rate.

How much heat or fan noise does the desktop unit produce during continuous operation?

The 8 oz desktop chassis has no fan and draws little power, so it runs silently with only gentle warmth.

Which cables and port must my computer already provide for this modem to work?

You need a free 9-pin or 25-pin serial port plus a straight-through serial cable, and a standard RJ-11 phone cord for the line.
