70 -- GROUND SUPPORT UNIT, MULTIPLEX/DEMULTIPLEX SYSTEM AND ACCESSORIES SOL N68936-96-R-0259 DUE 080296 POC Erica Freeman, Contract Specialist, 619-939-5427 Alita Gilchrist, Contracting Officer, 619-939-8168. The Naval Air Warfare Center Weapons Division, China Lake, CA, intends to award a contract to Aydin Vector Division for a Ground Support Unit (GSU) and two MiniARMOR-700 Multiplexer/Demultiplexer systems and accessories on an other than full and open competition basis. Aydin Vector Division is the only known company that can provide a GSU capable of allowing the user to perform troubleshooting, data analysis, and software programming of both CAIS components and Aydin Vector ALBUS 1553-1 instrumentation systems currently being utilized in the F/A-18 programs at NAWCWPNS. Aydin Vector Division is also the only known firm that can supply a multiplexer/demultiplexer meeting the requirements outlined in this synopsis. The GSU shall include one PST-800 card with manual. The PST-800 card shall be capable of the following: 1. Using direct connection to bit clock, frame clock, and serial NRZL data signals, acquiring a serial PCM stream up to 6 megabits per second of 1553 data per IRIG-106-93 chapter 8 format; 2. Providing full frame capture for class 1 (fixed format) and class 2 (asynchronous embedded format) as defined by IRIG-106-93; 3. Presenting acquired data per IRIG-106-93 chapter 8 labels or in raw, decimal, hex, or binary formats; 4. Displaying IRIG-106-93 chapter 8 data with or without fill words; 5. Displaying 1553 word type such as command, data, status, time, voice, discrete with bus identifier; 6. Automatically adjusting to changes in frame length and bit rate; 7. Providing a 32 bit input/output to direct data to external sources; 8. Performing complete integration and testing of Aydin Vector's ALBUS 1553-1 Programmable Bus Monitor; 9. Providing the ability to program the ALBUS 1553-1 internal user programmable devices; 10. Providing an IRIG-A/B/G compatible time code reader/generator function capable of synchronizing to an external time code source; 11. Allowing user to setup ALBUS 1553-1 options such as number of tracks, bit rate, bus ID, discrete word values, merge frame time, merge message time, merge voice, and merge discrete word. The GSU shall also include one CBE-850 CAIS Bus Emulator card with manual, and one CBA-850 CAIS Bus Analyzer card with manual. The CBE-850 card shall be capable of emulating a CAIS Airborne System Controller and CAIS bus command/reply traffic for Data Acquisition Unit (DAU) programming. The card shall allow the PC host to act as an active DAU. The card shall allow the viewing of 1553 data per IRIG-106-93, chapter 8 and shall be capable of providing a digital to analog converter output to display a selected 1553 parameter on a strip chart. The multiplexer/demultiplexer system shall have full backward compatibility with ARMOR-1 products designed and manufactured by Calculex Incorporated. The multiplexer/demultiplexer system shall allow aggregate bit rates up to 240 Mbps. The physical size of the chassis must be less than 350 cubic inches in volume, and no single dimension (height, width, length) shall be greater than 9 inches. The chassis and all expansion cards shall be designed to operate in a ruggedized airborne fighter aircraft environment (i.e. Mil-Std-810E). Interested parties other than Aydin Vector Division must respond in accordance with Note 22 of the Commerce Business Daily. See Numbered Note(s): 22. (0165)
