66 -- IN VEHICLE DATALOGGER SOL DAILEY DUE 073100 POC Ann Sanchez, (520) 328-6123 E-MAIL: Ann.Sanchez@yuma-exch1.army.mil, Ann.Sanchez@yuma-exch1.army.mil. Desired Characteristics for In-Vehicle Datalogger A. Purpose: To state desired characteristics for a datalogger to be used in non air conditioned military vehicles tested in a desert environment. B. Desired Characteristics: 1. 16 differential general purpose voltage channels (including +/- 5 Vdc and 0-5 VDC ranges) with anti-aliasing filtering available, simultaneous sampling supported, and bridge completion/strain gage capability, 2. 8 isolated differential thermocouple channels w/linearization and junction compensation (expandable to x channels) 3. 8 pulse counter inputs 4. 4 4-bit BCD switch inputs and x number of channels of continuous output (TBD as sensor dependent) 5. 2 RS-232 serial I/O -- one for a serial display of data at 1-second intervals (serial display is to be sunlight readable with dimmer controls for nighttime viewing) -- one for GPS data inputs (min of latitude, longitude, elevation, and direction or heading) 6. System time that can be synchronized to GPS and/or to IRIG B (RFrange time ) signals for time stamping of data scans 7. SAE J1939 bus data collection capability 8. Sealed for dust and moisture protection 9. 24 VDC power in with surge protection (from 24 VDC automotive systems) 10. 85 C Operating Temperature Range 11. Supports on-board math and statistical functions, histograms, limit and/or range comparisons, pseudo channels, etc. 12. Large on-board data collection capability (non-volatile) 13. Fast data download capability. 14. 10/100 Ethernet data output (for distribution and near real time viewing) and simultaneous on-board storage of data (the primary storage location) 15. Has or supports an external display (sunlight readable, dimmer controls, 1/4-VGA resolution and higher) with multi-page formatting of data for near real time viewing of data. 16. Has a given deterministic sampling interval between channels and supports the collection of data at multiple sampling rates. 17. Has a menu driven setup and data analysis package 18. Software that provides for near real-time viewing of the data via Ethernet and/or RS-232 19. Shock and Vibration rated suitable for use in off-road Military Vehicles Posted 07/12/00 (W-SN474086).
