2 Smart Star A/D Converter Cards (SR9300)
The Smart Star is a modular and expandable embedded control system whose configura-
tion of I/O, A/D converter, D/A converter, and relay cards can be tailored to a large variety
of demanding real-time control and data acquisition applications.
The typical Smart Star system consists of a rugged backplane with a power supply, a CPU
card, and one or more I/O cards. The CPU card plugs into a designated slot on the back-
plane chassis, which has seven additional slots available for I/O cards to be used in any
combination. A high-performance Rabbit 2000 microprocessor on the CPU card operates
at 25.8 MHz to provide fast data processing.
