So, if you are going to use a -+ Meinberg clock please ask whether there is a special Uni Erlangen -+ version. -+ -+ General characteristics: -+ Meinberg clocks primarily output pulse per second and a describing -+ ASCII string. This string can be produced in two modes. either upon -+ the reception of a question mark or every second. NTP uses the latter -+ mechanism. The DCF77 variants have a pretty good relationship between -+ RS232 time code and the PPS signal while the GPS receiver has no fixed -+ timeing between the datagram and the pulse (you need to use PPS with -+ GPS!) on DCF77 you might get away without the PPS signal. -+ -+ The preferred tty setting for Meinberg is: -+ CFLAG (B9600|CS7|PARENB|CREAD|HUPCL) -+ IFLAG (IGNBRK|IGNPAR|ISTRIP) -+ OFLAG 0 -+ LFLAG 0 -+ -+ The clock is run at datagram once per second. -+ Stock dataformat is: -+ -+ <STX>D:<dd>.<mm>.<yy>;T:<w>;U:<hh>:<mm>:<ss>;<S><F><D><A><ETX> -+ pos: 0 00 00 0 00 0 11 111 1 111 12 2 22 2 22 2 2 2 3 3 3 -+ 1 23 45 6 78 9 01 234 5 678 90 1 23 4 56 7 8 9 0 1 2 -+ -+ <STX> = '\002' ASCII start of text -+ <ETX> = '\003' ASCII end of text -+ <dd>,<mm>,<yy> = day, month, year(2 digits!!) -+ <w> = day of week (sunday= 0) -+ <hh>,<mm>,<ss> = hour, minute, second -+ <S> = '#' if never synced since powerup else ' ' for DCF U/A 31 -+ '#' if not PZF sychronisation available else ' ' for PZF 535 -+ <F> = '*' if time comes from internal quartz else ' ' -+ <D> = 'S' if daylight saving time is active else ' ' -+ <A> = '!' during the hour preceeding an daylight saving time -+ start/end change -+ -+ For the university of Erlangen a special format was implemented to support -+ LEAP announcement and anouncement of alternate antenna. -+ -+ Version for UNI-ERLANGEN Software is: PZFUERL V4.6 (Meinberg) -+ -+ The use of this software release (or higher) is *ABSOLUTELY* -+ recommended (ask for PZFUERL version as some minor HW fixes have -+ been introduced) due to the LEAP second support and UTC indication. -+ The standard timecode does not indicate when the timecode is in -+ UTC (by front panel configuration) thus we have no chance to find -+ the correct utc offset.
