Hi Luke,

I've helped a few customers connect NanoPower cables to ILEC SN10s with good
results.

My best guess is that the SN10 is not configured correctly. Or you have the
transmit and receive wires backwards. You must connect the receive line on
one end to the transmit line on the other end. You won't damage anything if
you get them backwards. If it doesn't work - swap them at one end (not
both).

Best Regards,

So... has anybody successfully gotten the LX-Nano to be the GPS source for
the SN-10? I've made my own RJ-45 cables to connect the two, but the
SN-10 refuses to acknowledge that there's a GPS attached. My volkslogger
blew up last spring, and we've not been able to make any use of the SN-10,
outside of the speed to fly function which still works.

I feel like kind of a pioneer here, except a lot less smart.

I wired the Nano to the SN-10 with the wiring instructions on page 12 of
the Nano handbook. Set the baud rate on both ends to 19200 (also tried
4800), NMEA. No soup.

Anybody got any ideas?

I have some bad feeling that it could be because of these reasons that I
haven't yet successfully eliminated as possibilities, (ranked by most
likely to least likely):

1) I'm not actually wiring it up in the way that I think I'm wiring it up
2) there's something subtle and different in the NMEA sentence structure
between the Nano and the SN-10 that won't be fixed by wiring.
3) the SN-10 is busted somehow.
4) The USB-to-serial cable that comes with the Nano is busted somehow.


If there is anybody out there who has successfully paired these two
devices before, I'd really like to know -- that way I can eliminate
possibility #2 above.



Hi Piet, I am not familiar with either piece of hardware so the
following is just a general statement that applies when connecting any
instruments together. My best guess is that you either have the baud
rate set incorrectly (settings on both units have to match), or the
cable you made has the RX and TX pins reversed from what is needed. You
can probably find the information on how to set the baud rates as well
as the pin-outs for the cables in the manuals of each instrument.

Good Luck,
