[time-nuts] TU-60 Instruction to set NMEA output

[Merv Thomas]

Hi All,

Thanks for the 2 prompt replies.

Tac32 does not have any facility to enter 1331 as an instruction.   It has 
numerous @@ commands but the TU 60 datasheets only list a small fraction of 
these commands and none pertain to setting the protocol!!  It is like it is 
a carefully guarded secret!

I downloaded Labmon which is a Navman proprietary software for the TU's but 
there does not seem to be a Win XP compatible version even though the one 
website stated it was for Win 2000/XP.  I installed it but it refuses to 
locate Comm 1 which is the port I have connected to its RS232 data output. 
It would handle the 1331 instruction if it would communicate with the port.

It is a real problem when doing things with fairly old GPS receivers and 
projects( eg I've just built the Shera GPS unit)which works well but there 
is no way I can get access to the .asm or hex files to play around with the 
software in the PIC as the originator is virtually inaccessible - does not 
answer emails.

Sorry for the mixed subjects in this.
