Interestingly enough, the Ublox LEA series of timing receivers has a USB port which you can connect directly to a USB cable. Of course you want to use an ESD device, etc. Bob ----------------------------------------------------------------- AE6RV.com

The USB interface timing is going to be buried deep, deep inside some microcontroller or ASIC. Imagine a FTDI part, for instance. I can't imagine a GPS mfr caring enough about this to spend any money on trying to figure out how to do it. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
