Fingerprint board isn't fooled by phoney fingers
Parvus Corp is developing modular fingerprint identification hardware for embedded computer applications in co-operation with Fujitsu Microelectronics America (FMA).
Measuring only 3.550 x 3.775in, the Parvus 1553/Ethernet interface uses Aeroflex UTMC's Summit MIL-STD-1553 support chip to operate as a databus controller (BC), remote terminal (RT), or bus monitor (BM) for a variety of 1553 military avionics and ground vehicle applications.
Four 16bit register locations allow complete access to interface functions through PC/104 I/O space, while test routines enable access to memory and internal registers.
The support chip also allows interrupts to be generated and routed to the PC/104 bus.
The Ethernet portion of the board is fully NE2000 and NE2000-Plus compatible and based on the popular National Semiconductor AT/Lantic AT DP83905 chip, taking advantage of this chipset's proven reliability and the maturity of drivers available in most operating systems.
The standard version of the board includes a 4-pin, low-profile Molex connector for 10BaseT connections, enabling a standard RJ-45 jack to be cabled out for panel-mounting in a faceplate, endcap, housing or bulkhead.
The PC/104 1553/Ethernet interface is specifically designed to work with transformer-coupled stubs in military LAN applications, including airplanes and helicopters, as well as space and land-based systems.
1553 technology is commonly used to process data for navigation and attitude, weapon status indications, target tracks and electronic warfare lines.
The board's Ethernet functionality expands its potential application into additional military communications environments.
