The ADAM-5511 is a PC-based programmable micro-controller for
standalone data acquisition and control which can control, monitor
and acquire data through multi-channel I/O modules. Its IBM-PC
compatible hardware and operating system runs programs written in
both assembly and high level languages. Each system can handle up
to four I/O modules (up to sixty-four I/O points). The system also
provides serial communication ports (RS-232/485), allowing the system
to communicate with other devices for versatile applications.
The ADAM-5511 system consists of two major components: the main
unit and I/O modules. The main unit consists of a CPU card, a power
regulator, a 4-slot base, two serial communications ports and a
programming port. It has the following major features:
Built-in 80188 CPU and ROM-DOS operating system
ADAM-5511's CPU card includes an 80188 microprocessor. Its ROM-
DOS operating system is an MS-DOS compatible system. It provides
all the basic functions of MS-DOS except the BIOS. Users can run
standard PC software or application programs written in high level
languages under this ROM-DOS environment.
Built-in ROM and Flash disk for programming
The ADAM-5511 has a built-in flash ROM, SRAM and flash disk. The
system provides 400 KB of free flash disk to allow users to download
programs. There are also 12 KB of free SRAM with battery backup to
provide the memory needed for temporary variable storage in user's
programs.
Built-in RS-232/485 communication ports
The ADAM-5511 has two serial communications ports to enable the
controller to communicate with other devices in your applications. The
COM1 port is dedicated as an RS-232 interface. The COM2 port is
