CY600 Overview

The CY600 Analog/ASCII™ Data Acquisition Controller is a five-volt, TTL compatible 40-pin device, that is designed to monitor voltages from an A-to-D converter and continually test specified conditions, using an instruction sequence that is stored internally in a channel buffer. The CY600 will work with one to four channels, executing separate code for each channel. Each channel contains a set of 16-bit registers with ASCII names and accepts ASCII operators: ( = > < + - * / ). When a relational test is satified, the CY600 generates an interrupt to the master computer that can then query the CY600.
