I was looking for an app for the CW46, which uses the same GPS engine. The
Navsync doc mentions NS3KView and
You are right. There is no "frequency set" command in WinOnCore, but you
can simply type in $PRTHS,FRQD,0.01 and press return to send the command
from the command window. That's what did.

A "frequency set" command in WinOncore? The WinOncore was designed by

should be on its way to Italy right now. I have 2 TBolts but not yet turned

We (that is my company) use the CW12-TIM (NMEA version) and its PPS wonders
as usual, nothing different from a uBlox LEA-5T or the M12M.

I spoke with Navsync about some of the issues we are discussing and this was
their response. I just received mine and will try to test it over the weekend.
1. Is CW12-TIM compatible with Motorola M12 ?>>
The CW12 is designed to be compatible with the M12 although there are
some differences. Th
am interested in the firmware to fix the 10MHz issue in case I ever utilize
the variable freq output.

Search the archives and you'll find out more about it. One thing to
note is that the CW12-TIM doesn't support sawtooth correction so the 1
PPS may or may not be an improvement over the M12+.
