FREMONT, Calif. – Elma Electronic Inc. in Fremont, Calif., is introducing a 12-slot 3U embedded computing design and development chassis for systems designers who need alignment to the Sensor Open Systems Architecture (SOSA) and the C5ISR/EW Modular Open Suite of Standards (CMOSS) design guidelines.

The chassis aligns to the SOSA 1.0 and CMOSS open-systems standards, offers high-speed RF and optical I/O, and supports I/O- and compute-intensive processor slots, two switch slots, and one PNT slot.

The development chassis and test and measurement system for embedded computing provides a complete test environment to support application development for SOSA and CMOSS initiatives.

"Now that SOSA 1.0 has been released, streamlining development time of SOSA aligned systems is critical, so that we can speed time to market and shorten deployment of these open standards-based systems," says Ken Grob, director of embedded computing at Elma.

This chassis was part of an interoperability demonstration last March that involved three additional SOSA member companies at the Tri-Service Open Architecture Interoperability Demonstration (TSOA-ID).

The chassis also provides two VITA 62 power slots, and is built on an Elma Type 39 84HP-wide E-Frame chassis that provides open access for testing and troubleshooting.

Other options include dual high-wattage VITA 62 3U VPX pluggable power supply modules, a network timing card with radial support for IEEE 1588 precision timing and synchronization, and a 4590a 1/10/40 Gigabit Ethernet switch with copper and fiber ports from Interface Concept.

Also featured are conduction-cooled slot inserts, front and rear fan trays with 12-volt DC fans and AC operation using a power cord. The platform includes a front panel on/off switch, reset switch, voltage LEDs, and test points.
