ADAM-4500

ADAM-4500 PC-based Communication Controller Features  Powerful communication controller in a small package  Built-in Boot ROM DOS to run PC programs  Free ROM/RAM memory for user's applications  2-wire, multi-drop RS-485 networking  Communication speed up to 115.2 Kbps  RS-232/RS-485 modes (jumper selectable)  Automatic data flow control in RS-485 mode  Built-in real-time clock and watchdog timer  Easy mounting on a DIN-rail or panel  Accepts unregulated power sources between 10 to 30 VDC  Program download cable and utility included 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.

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.
