[time-nuts] FASTRAX GPS

[Ernie Peres]

Hi Jason,


I figured out a different pin assignments....

hold the PCB so that the SMA antenna connector is looking to right and under the PCB.

open-   1      2-  Ant power    presently connected to pin nbr 4
    TX-   3      4-  Main power  +3 volt
     RX-  5      6-  1PPS
 open-   7      8-  Grnd   power -3 Volt

the unit takes about 60mA @ 3,0 volt and comes-up in NMEA mode.. 9600 Baud.
I use the FASTRAX_WORKBENCH_522 software.
I wonder if anybody has other pin arrangement/connection. The 2 open pins is UNK and also not sure if pin nbr 4 is the main power or perhaps the pin nbr 2......??

Rgds Ernie.

Ernie,
I'm having issues right now, I need to find my adapter cable as the one I have 
ight now is the wrong pin spacing. I did trace the
ines on the PCB and it appears to be the same as the Resolution-T / Lassen / 
ther Trimble pinouts...
Just FYI, I couldn't find a valid link to the 3.41 software since ublox bought 
hem and they only have a newer version which I don't
hink supports the old binary protocol, they only support NMEA (supposedly)... 
t probably wouldn't hurt to try them out later
hough. I do not know what language the module will start out in...
I did find an older version on the archive.org website, link is below:
https://web.archive.org/web/20070227050436/http://isuite.fastrax.fi/download/gpswb/Setup331.exe
If you dig around on some newer pages there is also a link to a firmware 
ownload and the updater software that works.
The pinout for the board *should* be:
1 - Antenna Input (5v - 3V I guess)
 - Prime Power - 3.3V
 - TXD
 - Reserved
 - RXD
 - 1PPS
 - No Connect
 - GND
If you hold the module so the SMA is on the LEFT (bottom side), and the pins are 
n the far RIGHT facing up.
GND - 8 7 - NC
PS - 6 5 - RX
ES - 4 3 - TX
WR - 2 1 - ANT
For verification, if you look closely you can see the trace going out from Pin-2 
's up and down.

Hello,
Thought this could be of interest to some of you:
