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 broad­casted 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 ac­tive 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 inter­ferences. 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.

Features of EMC Prof NET (19“):

 Digital filter and intelligent failure correction
 Signal monitor with LED line
 Battery buffered real time clock
 Stand-alone Time server (SNTP)
 Νetwork configuration via DHCP
 Configuration over Ethernet (HTTP)
 Programmable Relais switch (without potential)
 Syslog
 SNMP (v1, v2c)

2.2 Installation

1. Connect the active antenna and the power adaptor/power
cable with the connectors at the device. If you are using EMC
Prof NET 19“, activate the device. EMC Prof NET (19“) is now
booting and shortly after ready for usage.

2. Connect EMC Prof NET (19“) with your network or via serial
interface with your pc.

2.3 Display

After power on the LC display shows the configuration and the
version of the firmware.

After a few seconds EMC Prof NET (19“) shows its IP address
followed by the up-to-date time and date.

First EMC Prof NET (19“) is in quarz mode. Beside the time
“Quarz” is shown in the display. Even in quarz mode EMC Prof
NET (19”) is completely ready for use.

It looks for a proper radio signal. Approximatly after two minutes
EMC Prof NET (19“) has received enough information to switch
into the radio mode. Then it shows “F=...” in the display, which
means the number of faulty received bytes within in the last ten
minutes.

When you receive a good signal quality, the LED line will swing
fully once a second and the clock LED will blink every second.
The radio time LED will shine green constantly.

2.4 Alignment of the active antenna

Local issues may have influ­ences on the received quality
of the signal. Barriers like re­inforced concrete buildings or
mountains may weaken the sig­nal, the electromagnetic fields of
screens or motors may disturb
the signal, too.

EMC Prof NET (19“) was de­veloped in aspect to be used in
an electro-magnetic disturbed
environment. With its active an­tenna and optimized electronic,
EMC Prof NET (19“) offers a
good receiving even in such
ambience.

To obtain a good receiving, please attend to the following hints:

 Do not place the antenna near by or directly on metallic,

or conductive objects.

 Place the antenna near by a window. If neccessary it

is possible to mount the antenna outsides, in this case
make sure, that there is an adequate lightning proctec­tion.

 Do not place the antenna parallel to telephon/network or

power cables.

 Change the direction and the position of the antenna

until you get a good receive quality (See figure 5).

Since the time signal moves cir­cular from the sender in frankfurt/
Mainflingen, you will get the best
receive if you place the antenna
tangential to these circles.

antenna

 Interferences may be exactly at 77,5 kHz or broadband

interferences, which meet 77,5 kHz. Devices like moni­tors or devices using a power adaptor are known jam­ming sources. Do not place the antenna near by those
objects.

 Athmospheric interferences occur like shortwave radio

in batches, up to a few seconds. To secure the received
quality, we recommend to change the location of the
antenna.

When you receive a good signal quality, the LED line will swing
fully once a second and the clock LED will blink every second.
The radio time LED will shine green constantly.

3.1 EMC Prof NET (19“) as SNTP-Server

Due to its integrated ethernet interface EMC Prof NET (19“) can
be connected to a network and is able to act as a stand alone
time server. The SNTP protocol allows client in the network to
synchronize the time with EMC Prof NET (19“).

3.2 Time synchronization as SNTP-Server

The following chapters show how to synchronize your PC clock
with EMC Prof NET (19“) while using a MS Windows OS.

3.2.1 Windows XP/Vista

If you are using Windows XP or Vista, you do not need additional
software to synchronize your PC with EMC Prof NET (19“)
First, open the date and time information by double clicking on
the clock in the task bar. Now choose the tab Internet time and
enter the IP address of EMC Prof NET (19“) into the field Server
(see figure 6).
By clicking at Update
you can check the syn­chronization.
Close the configuration
by clicking at OK. Win­dows will automatically
synchronize the time
from now on.
