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).
