The manufacturer does not accept responsibility in case of im- proper use of the device and particularly any use of equipment that may cause personal injury or material damage.

  • Page 6: Description

    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.

    2.4 Alignment of the active antenna Local issues may have influ- ences on the received quality of the signal. Barriers like re- inforced concrete buildings or mountains may weaken the sig- nal, the electromagnetic fields of screens or motors may disturb the signal, too.
  • Page 11  Interferences may be exactly at 77,5 kHz or broadband interferences, which meet 77,5 kHz. Devices like moni- tors or devices using a power adaptor are known jam- ming sources. Do not place the antenna near by those objects.  Athmospheric interferences occur like shortwave radio in batches, up to a few seconds.

  • Page 12: Network Operation

    3 Network operation 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“).

  • Page 13: Windows 9X/Nt/2000

    3.2.2 Windows 9x/NT/2000 While using Windows 9x/NT/2000 the easiest way to synchro- nize the internal PC clock with the EMC Prof NET (19“) is the tool Dimension 4 (D4). To synchronize the PC with EMC Prof NET (19“), click on the button Add.

  • Page 14: Linux

    3.2.3 Linux Under Linux, there are several ways to synchronize the PC clock with a network time server. This chapter shows how you can synchronize your PC clock with ntpdate and cron. Please check, if ntpdate is installed already. Therefor, please use the command „which ntpdate“.
  • Page 15 For a regularly synchronization, you have to create a cronjob. A cronjob is command, done by cron. We recommend to start ntp- date with the parameter „-s“. With „-s“ the command line output of ntpdate will be written into the systemlog. To create a cronjob, you have to start crontab -e.

    4.1.3 Interface At the w32EMC window (figure 11) you can see the following values: DCF77-State System time The time and date of your PC. Last received The last correct received DCF time and date. Operation mode It is indicated here if EMC Prof NET (19“) is in radio or in quarz mode: „Radio mode“...

  • Page 19: Logmode

    V.24 V.24 State The state of the data transfer of the serial interface is shown here: „active“/„active in ... seconds“: DCF time signals are re- ceived at serial interface of the PC. The system time is compared with DCF time. „No receive!“: There is no receive of signals at the choos- en serial interface.

  • Page 20: Operation Under Linux (Ntp)

    4.2 Operation under Linux (NTP) EMC Prof NET (19“) can be used with NTP under Linux. „NTP“ means Network Time Protocol. It is designed for the synchroni- zation of clients over TCP/IP. For the usage under Linux the V.24 output protocol has to be changed to XNTP (see chapter 5.3). 4.2.1 NTP installation For easy installation of NTP you can find the shell script make_ all.sh on the CD-ROM at „tools\linux\get_ntp“.

  • Page 21: Starting Ntp

    You have to enter the following lines into the file ntp.conf in order to receive the time and date information of EMC Prof NET (19“) regularly: server 127.127.8.0 prefer mode 12 logfile /var/log/ntp logconfig =all driftfile /var/log/ntp.drift This means, the time and date information of the device re- fclock-0 will be picked up by driver 12 of group 8.
