INTRODUCTION

The Equinox MEGAPORT, MEGAPORT/2 and MEGAPORT/RS
family of multi-user boards provides the highest performance serial
I/O solution for UNIX, XENIX and AIX applications in ISA, EISA
and Micro Channel bus systems.
Except for the computer bus interface and an additional step in the
hardware configuration process, MEGAPORT/2 and MEGAPORT/RS
products are identical to their MEGAPORT counterparts. In this
manual the term MEGAPORT refers to all nineteen products:
ISA and EISA Bus Products:
MEGAPORT 8CS: an 8-port board with standard RS-232
interface and modem control signals on all ports. This
board is not addressed in this manual; refer to the
MEGAPORT 8CS Hardware Reference Manual, Equinox
part number 560044.
MEGAPORT 12CS: a 12-port board with standard RS-232
interface and modem control signals on all ports.
MEGAPORT 24CS: a 24-port board with standard RS-232
interface and modem control signals on all ports.
MEGAPORT 12FM: a 12-port board with standard RS-232
interface and full modem control signals on all ports.
MEGAPORT 12LD: a 12-port board with on-board line
drivers for long distance applications which do not require
modem control signals.
MEGAPORT 24LD: a 24-port board with on-board line
drivers for long distance applications which do not require
modem control signals.
MEGAPORT 12LD+12CS: a 24-port board. The first 12
ports use on-board line drivers for long distance
applications which do not require modem control signals.
The second twelve ports provide the standard RS-232
interface with modem control signals on all ports.
