[time-nuts] Trimble SMT board

[Erno Peres]

Hi David,

I have chked vith TAC32 SW, 9600 Baud  and Motorola binary code and  it is working OK.  .... even will initialize the SMT gps board when there is a power interruption and no any protocol comes out.
Also chked with the  Winoncore  SW and it display data but not all.. and this SW does not initialize the SMT board.

Of course and Trimble gps Studio is OK.

Hope this helps a little.

Rgds Ernie.

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

S.  for what board / gpsdo / do you use  the SMT gps..????

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