Hi Everyone.
Thanks for the suggestions.
I would be perfectly happy with 9600 baud output except for the
TinyTracker3 only taking input at 4800 baud. I've used a few computers now
and the results are the same - perfect 9600 baud and garbled 4800 baud.
The Uniden GPS301 is a Sony IPS GPS in a Uniden case and a LED display to
show waypoints, red light cameras etc. The IPS is directly addressable
through the Uniden's serial port - i.e. I can issue @NC 00000000 and all
the NMEA output switches off. This all works at 9600 but not at 4800. The
(little) information I can read about the IPS GPS is that it's serial port
speed is set with jumpers, so I'm assuming the GPS301 firmware takes care
of setting those.
I don't have a CRO but can get my hands on one...
I've emailed Uniden to see if they can confirm if 4800 baud output should
work properly. Perhaps mine is faulty? <shrug>
