The compact, rugged module is engineered to meet the wide operating temperature, high shock and vibration, and mission-critical reliability requirements of fixed and mobile application environments, whether indoors or exposed to the elements.
Corona reduces cost, size, weight, and power, by enabling embedded system designers to pack more I/O into spaceconstrained enclosures,” says David Fastenau, director of marketing at Diamond Systems. “This rugged multifunction module was designed with outdoor applications in mind, and is an ideal solution to the wireless access point and high-density data storage challenges of numerous industrial automation, energy management, mobile data acquisition and control, and intelligent transportation systems applications.”
Within a single SUMIT-ISM Type I form-factor module, Corona integrates the following features:
Socketed 802.11a/b/g WiFi radio card (located on the top of Corona)
Two 10/100Base-T Ethernet LAN ports
Two USB 2.0 ports (derived from SUMIT-A bus signals)
Mounting location for an optional 2.5-inch SATA SSD card (located on the bottom of Corona)
SDVO-to-VGA converter (usable with Diamond’s Aurora SUMIT-ISM single-board computer)
SUMIT-A (PCI Express) and PC/104 stackthrough buses
ISM form-factor (3.55 x 3.775 in; 90 x 96 mm)
Extended operating temperature range of -40°C to +85°C
Corona’s onboard 802.11a/b/g WiFi function is based on a socketed wide-temperature mini-PCI card, which implements a dual-channel/dual-antenna WiFi radio and supports 108Mbps transmit/receive rates, average power of 23dBm, and peak power of up to 28dBm. The module’s onboard SDVO-to- VGA converter can be used for converting the SDVO output signals of Diamond’s Aurora SBC into standard analog VGA format. The optional onboard 2.5-inch SATA solid state disk (SSD) accommodates local data storage prior to its offload via either Corona’s WiFi or Ethernet communications functions. Diamond’s board-level 2.5- inch SATA SSD modules (SSD-32GB-XT and SSD-64GB-XT), also being announced today, further simplify system integration and reduce size, weight, power, and cost. Corona derives its PCI Express and USB host interface signals from the host SBC’s SUMIT-A connector, but does not use signals or power from its PC/104 bus stackthrough connector. The two types of stackthrough buses (SUMIT-A and PC/104) enable SUMIT and PC/104 modules to be stacked above Corona in systems supporting those buses.
