Introduction
The ADAM-4500 is a fully functional stand-alone controller for industrial automation and control. It provides an ideal environment for controlling PC hardware with a minimal amount
of development effort. Its built-in ROM-DOS lets users run standard PC programs or new programs produced by PC language development tools. ROM-DOS is an MS-DOS equivalent
operating system allowing you to run all standard PC software.
Built-in RS-232/485 COM Ports
The ADAM-4500 has two communication ports (COM1 and COM2). These provide easy communication between the controller and other devices in your applications. COM1 can
be configured for RS-232 or RS-485 communication via a jumper setting, while COM 2 is dedicated as an RS-485 port. This design allows the controller to be used in a variety of
applications. For example, a user can download an application into the ADAM-4500's on-board Flash memory while the ADAM-4500 is connected to an RS-485 network, then let it
control all the modules in the network.
Built-in Real-time Clock and Watchdog Timer
The real-time clock in the controller ensures accurate time recording while the system operates. The watchdog timer is designed to automatically reset the CPU if the system fails.

Software
The ADAM-4500 module provides 170 KB ROM for your downloaded applications and
234 KB RAM for application operation. Its built-in ROM-DOS is an MS-DOS equivalent
operating system, which provides all of the basic functions of MS-DOS except BIOS.
Application programs written in high level languages such as C or C++ can run under
ROM-DOS. Application programs should be converted into 80188 compatible code
before being downloaded into the ADAM-4500. The download utility is included with
the ADAM-4500.
