CY250 Overview

The CY250 Local System Controller coordinates the operation of any two Cybernetics peripheral controllers, such as the CY512 Stepper Motor Controller, the CY360 Waveform Synthesizer, the CY600 Data Acquisition Controller, etc. The CY250 will control two such chips in any combination. Through its serial or parallel command interfaces, the CY250 will connect to a CRT with an RS-232-C port, or to a master computer either directly or in a network configuration via the CY233 Network Controller. The CY250 provides for hierarchical control of sophisticated systems in a flexible, powerful, yet easy manner.
