two things YOU can try:
1) Go to google translate https://translate.google.com/ and type in
the URL of the German web page. It will translate the site to English

2) Use Goolge's Chrome web browser and it will automatically
translate non-English sites for you.
Neither are perfect

One thing to be careful with when running VLF into NTP - make sure you work out
the propagation delay to your site and put it into the driver. As your data
shows, the jitter is low enough to make it worth doing.

Hi Rudolf,
The Pickit2 configuration choices were a bit confusing, so I decided to order a
different serial board that contains actual 16550s. Now that I've had a chance
to assimilate what I've learned, the problem is traced to the 3 Volt 3243 chips
that are in today's serial boards. After
What a find. I tracked down the docs. It will do NMEA and has 20ns RMS
time error.
Looking at the photo I can trace the header pins visually. The traces seem
to be all on one side. The linked doc give the pinouts for the chip.
I'm thinking I want one of these too $12 with free shipping is
Thanks to all who replied. It seems that the item is not available

I have 2 x M12+T , and a DS1023-100 Dallas chip.

One quick approach is to let gpsd try. It's very good at figuring out what

I normally use gpsmon. By default, it doesn't send anything, just listens
while searching baud rates. The i
The ref output is the minimal delay through the chip covering the input and

There are no negative delays in that sort of chip. It's just a bunch of
gates/buffers with a carefully calibrated delay. (For a negative delay,
Hi
The DS1023 will not do negative delays. Physics people would be very interested
in it if it did.
You will need to add a nominal delay of 1/2 the max DS1023 delay to the data
coming out of the M12. Also pay careful attention to which PPS the message
applies to (the most recent one or the
from page 167 of user 09feb05 version of user manual: It is an 8-bit
value n where n = negative sawtooth time error of next pulse The
value of N ranges from -128 to +127.
I think(?) it is really a value from 0 to 255 and you must apply a
bias to get the -128 to +127 range. And again this is a
As you can tell from the manual, the M12+ and the M12M will output a
signed -128..+127ns correction from the @@Hn message. In my opinion
you have to start from a fixed delay (an offset) in order to apply the
negative correction. I already have the Dallas/Maxim delay line but
still not used it.

Hal,
Yes, there are negative delays. The goal is that the physical 1PPS output is,
on average, exactly on-time. If designed right, that means as many negative
offset pulses occur as positive offset pulses. The spread gives you the RMS
value.
This is exactly what you want for a GPS timing
Chris,
The manual clearly states -128 to +127. What's your problem with that?
Yes it gives that range. It says the value is stored in 8 bits.
But how is it stored? Certainly not as sign bit and 7 bit magnitude
or you could not have -128.They don't say but options are either
an assumed
-128 is 0x80
+127 is 0x7F
If in doubt, just look at the sawtooth correction messages coming out of your
M12.

I think there is confusion between where there is a negative delay. Yes the
M12 can have a negative value but in order to correct for the full range
of the saw tooth at zero the DS chip has to add 128 nsec delay plus the zero
value. Depending on the message it ads or subtracts from that
The question is what is the definition on time. Yes it will be always 140
nsec late to what the M12 calls zero. Good for a GPSDO. How ever if you want
it to relate to NIST time more hardware is needed unless you can
compensate that 140 nsec in antenna delay.
A simple solution would be a

So it's twos complement to negate a number you invert all the bit
then add one.
The fun part of 2's complement is when you count in binary from -1 to +1
