OpenDS v1.0
Open Development System openDS v1.0 is a modular and expandable embedded control system designed for the most demanding real-time control and data acquisition applications that can be used for educational purposes also. Multiple I/O options, including digital, A/D, D/A, allow users to closely match their specific I/O needs. The openDS v1.0 CPU card comes with an Ethernet conectivity.
Features:
Ethernet connectivity—CPU
Flexible functionality—modular configuration to easily interchange or replace individual I/O cards
To make integration easy, the openDS v1.0 is been designed from the ground up, with careful consideration given to configuration, implementation, and maintenance requirements. Modular expansion allows you to use the same openDS architecture in both small or large applications and where cost and physical size are critical.
The basic openDS v1.0 system consists of a backplane with power supply, a CPU card, and one or more I/O cards of your choice. The openDS v1.0 backplane has 5-slot. With one slot on the backplane reserved for the CPU, remaining slots can be used for any combination of I/O cards, giving designers a customizable platform for their applications. The CPU card is powered by the Cygnalâ„¢ microprocessor operating at 100 MHz, 100 MIPS and features 128K of Flash memory. More information here.
