Hi, David,
We are facing a sync problem.We deployed 8 ROACH2s in our system now.Taught as 
the PAPER model ,I connect a 1pps in the sync_in port of pf1,and put signal out 
from sync_out of pf1 into the sync_in of pf2,and so on. When I run the 
paper_init.rb to initial all the 8 ROACHes,However The different ROACH has 
their own sequence of MCNT . Different ROACH(different FID) send the different 
MCNT in the same time,which should stay the same.
I thought it is a 1PPS sync problem ,I want to use a power divider to split the 
1PPS signal into 8 ways to each ROACH.But the power divider did not work in our 
lab. (I thought the power divider need to be special) Do you have some good 
suggestions?
Thanks for your help again!
Peter
