DEWETRON has developed a comprehensive interface to the Tarsus PCI-PCM, an FPGA-based bit-sync/frame sync/decommutator interface card. This is a PCI form factor card, allowing it to be added to virtually any DEWETRON instrument, from very portable battery-powered units, to larger rack-mounting ones.

The bit sync and frame sync are handled in hardware via the graphical user interface within DEWESoft, whereas the decom is implemented entirely in software. This allows maximum system flexibility, including the ability to handle one or more embedded asynchronous data streams.

The hardware can handle PCM data in numerous popular formats, and at rates up to 33 Mbps. This hardware and software combination, installed within DEWE-901 instruments, is heavily used by NASA’s Kennedy Space Center on the US Space Shuttle program, and will be used on Constellation as well.

• User interface guides through all steps
• FPGA based hardware for flexibility and easy upgradability
• Every graphical widget from DEWESoft can be used to display parameters from PCM
• On-line mathematics and scaling functions
• Programmable display types show user-defined text in response to discrete values received on any channel
• Sychronized PCM, Analog, ARINC 429, and 1553 is possible due to DEWETRON’s unique architecture
• Video input can be added to most systems
• Convenient PCI form factor interface card
• Multiple cards can be added to one system
