Hi David:

Since the counter is a Systron Donner (not the SRS 620) I expect that 
the PRS10 is being used in the mode where it emulates an Efratom 
Rubidium brick.  I.e. the 1 PPS GPS input is not active in this mode 
although the counter may be able to be modified to add the 1 PPS input, 
1 PPS output and RS-232 coms.

Have Fun,

Brooke Clarke
