Required Equipment
In addition to the contents of the MT2834ZDX package, you need the
following equipment.
Computer
The MT2834ZDX can be connected to any computer with an RS-232C/
V.24 serial port, such as the IBM PC, XT, AT, and PS/2 computers, and
most PC compatibles. It can also be connected to the RS-422 serial
ports on Apple Macintosh computers. To use your MT2834ZDX at its
highest speeds, a PC must have either a serial port with a 16550AFN
UART or a Multi-Tech ISI (Intelligent Serial Interface) card, such as the
ISI551 (single port), ISI552 (dual port), or the ISI608 (eight ports). A
16550AFN UART can safely handle data at rates up to 115,200 bps.
Almost all Macintoshes can handle data rates up to 57,000 bps, while
the newer ones can handle data rates up to 115,000 bps.
Serial Cable
To connect the MT2834ZDX to your computer, you must provide a seri-
al cable, obtainable at computer stores and many office supply stores.
The cable should have a male DB-25 connector at the modem end. For
IBM and compatible computers, the other end may have a female DB-
25 connector or a female DB-9 connector, depending on your comput-
er. Most Macintosh computers require a round, 8-pin, mini-DIN
connector. The Macintosh serial cable should be wired for hardware
flow control. To reduce electrical interference, the FCC requires that the
cable be shielded.
