David, this could be a possible problem as the GPS receiver deliver signals from 0 to 5V and not true TIA-232 levels (-9V to +9V). I thought at this situation several months ago but I'm not sure if such a converter will not add too much jitter to the PPS signal (as it must be supplied with a separate voltage source). _______________________________________________ questions mailing list [email protected] https://lists.ntp.isc.org/mailman/listinfo/questions
