Hi David,
thanks a lot for the info,.... I have also the 1PPS output, but had the
impression that it will also output TSIP or any other kind of MSG upon
power-up... and you can configure the board as required of the need.....it
outputs according to the TrimbleStudio SW is TEP format but any
interruption of the power / +3.3 V / then no any msg comes out..!!!!
I want to use for the Brook Shera board....so the 1PPS is OK.
I did not chked out with the Motorola software or TAC32 but will do.
Rgds Ernie.
PS. for what board / gpsdo / do you use the SMT gps..????

Ernie,
I will be interested to know whether the Motorola format works so look
forward to your report back. I have no definite use for the board - it just
sounded like a good buy. My interest is more in time than frequency, so I
could use it for PPS generation for NTP on a PC, with the Internet or other
servers providing the nearest second and the device providing the actual
second edge. Having seen how short the pulse is, though, I am uncertain
whether it would work directly. I already have Garmin GPS 18 LVC, 18x LVC,
and Sure Electronics PPS sources, but having a third manufacturer (and one
as highly rated as Trimble) can't be a bad thing. <G>
There is also a remote possibility to use it in a stand-alone
multi-lateration device, although the non-standard output format could
scupper that! It uses an older Trimble SMT board.
