hopefully somebody on this list has a TrueTime GPS-DC ...
I've just set up my new (to me) GPS-DC MK III. It seems to be working
(gets a fix, show itself as locked and the stats look fine). The 1PPS
output works and is currently syncing one of my NTP boxes. However I
can't get the RS232 output to work. What I'm seeing is anything I type
on the RS232 is ignored except <CR> which get a "?" is response. The
book says F08<CR> should cause it to output time once a second but it
doesn't.
The data rate/parity etc is right so I'm stumped. Is there some magic
to getting this thing to talk on the serial port?
