The Palisade driver supports several different variations of
Trimble products.  Which one(s) did you try?

The data sheet says it speaks TISP and NMEA.  I don't know which
one is the default.  You might try running some helper code 
before starting ntpd to switch it to NMEA mode, and then telling
ntpd that it's a NMEA device.

These are my opinions, not necessarily my employer's.  I hate spam.
