Stable Real Time Clock
Model PCRTC
PCRTC dramatically improve accuracy your computer's clock. PCRTC real time clock based highly stable oscillator circuit. PCRTC`s clock, using software driver provided, used update clock every minute. This allows user applications access correct time without special commands function calls. PCRTC additional features that either incorporated using provided "include file" making function calls within your program, from command line using PCRTC.EXE file. first these functions battery status. checking battery status take action battery before time corrupted. second function time last power loss reset. checking this function, time last host computer power loss system reset determined.
Specifications
Setup Address: Programmable with four position switch Interrupt: None required bus, short bit) slot Clock Resolution 0.01 seconds Oscillator Temperature Stability: Calibration: (room temperature) Aging: Power Requirements 5VDC Battery Requires lithium battery 3-4V backup power Battery Life: approximately without host computer powered. Replacement batteries available from Electronics, order part number 3345. Dimensions:
Programming with PCRTC
high resolution (0.01 seconds) PCRTC gives programmers much higher resolution timer than available from most time calls which usually only accurate nearest timer tick. "include" file Pascal, QuickBASIC provided allow simple function calls read time, check battery status time last power down reset. Sample programs demonstrating make these calls provided each three languages.
