MS Windows-based timekeeper is designed to activate remote signal lights that are connected to computer's serial port through D'San Corporation's proprietary interface products. LimitimerPC is ideal for court clerks and city council clerks who are seated nearby at their computers during meetings. Small application window allows them to work on other applications and monitor timer. Time settings are stored in files with an .ltm extersion. Files also define timing configurations such as advanced or simple. Advanced configuration provides extensive control over light activation. You can set on and off times for green, yellow and red lights and monitor time remaining for two different speakers. Simple configuration mimics Limitimer protocol such as set total time, set sum-up time. Red always comes on at zero time remaining. When you launch LimitimerPC, last saved timing session file is automatically loaded. It is possible to preset different configuration and load any of these when needed.
