EMC Professional NET
1 Description
EMC Professional NET
(
EMC Prof NET (19“)
) provides ac-
cess to one of the most exact working atomic clocks in the
world. It is run by the Physikalisch-Technische Bundesanstalt
(PTB) in Braunschweig/Germany. Time and date are broad-
casted by the DCF77 long-wave sender in Frankfurt/Mainflingen
in Germany on a frequency of 77,5 kHz. The broadcasted time
and date information are CET/CEST. The range of DCF77 is
about 2000km.
EMC Prof NET (19“)
receives
the DCF77 signal, using an ac-
tive antenna. The received time and date information can be
published in a network using NTP or via serial interface to a
single PC.
EMC Prof NET (19“)
acts as stand-alone SNTP-Server. All PCs
in the network can synchronise with
EMC Prof NET (19“)
.
EMC Prof NET (19“)
was designed for a safe implementation
in a environment, which is polluted by electro-magnetic inter-
ferences. To secure a proper receive,
EMC Prof NET (19“)
is
equipped with a precise electronic.
In case of longer receiving problems,
EMC Prof NET (19“)
automatically switches to its internal battery buffered real time
clock and provides further on the exact time and date. When
the quality of the received signal has gone good enough again,
EMC Prof NET (19“)
switches back to radio time.
