Description:
With the radio clock receiver that is connected to the PC card, the time measure of Mainflingen is received on long wave 77 kHz and transmitted to the software. The time is actualised every minute. A DOS background program (for DOS and Windows 3.1x) is supplied as well as drivers for Windows 95 and Windows NT 4.x.
Usage:
The CLOCK77 can be used in networks to make uniform the times of all PC clocks, but as well in a stand-alone home PC if the user does not want to bother with the system time.
Glossary:
Atom-exact time:
in this case indicates a difference of one second in 300 000 years.
