Hi David,
I sent off the query/problem to them a few days ago via the online
form - alas no reply as yet though.
I've had problems my end anyway the box this is attached to decided to
die and I had to replace the CPU which did all sorts of odd things with
the clock and required a change of timer source to stop the thing
running mad. It's taken a couple of weeks for it to sort its self out
and the jitter/offset to come back down to what they where.
Anyway if I hear anything back I'll post here.
I hope that Garmin at least acknowledge your request - let's hope the
delay means that it being passed on. Sorry to hear about the box
problems - I replaced my Pentium 133 system with a fanless Intel Atom
system when that happened. The 18x is now being used just as a PPS
reference on my Windows-7 SP1 system (and I think SP1 has stopped the
glitches I used to see, so better timekeeping), with the NMEA part set to
"noselect":
____________________________________
# PPS serial port driver - uses serialpps.sys
server 127.127.22.1 minpoll 4 # PPS using serialpps.sys
# NMEA serial port driver
server 127.127.20.1 minpoll 4 mode 33 noselect # 19200bps, NMEA
serial port
____________________________________
Checking further, before SP1 averaged jitter was 22 - 80 microseconds, and
after SP1 18 - 28 microseconds, so Windows-7 SP1 has helped the
timekeeping.
Cheers,
David
