MessageHi Michael,

The file "r2_enhpps_30_1.txt" on the configurations zip folder
has it all.
I agree it is in a "very compact style" but in fact should have it all.
Take a look, and if there are specific questions, let me know
(do it to the list please) I'll be glad to reply.

Luis Cupido.

P.S. note that the N numbers on the PCB have different meaning for
each "pof" configuration file. Be sure to read the " *.pin " for the description
of where is what.

The  " f_conf "  configures the lock point (that is the multiple of ).
for 100. 000 000 MHz use f_conf= 0,0

  Subject: [time-freq] RefLock II configuration

  I went out on a limb to convince my employer to try the RefLock II as a means of locking 1PPS to a 100 MHz OCXO.  Now we have received two kits and it's my responsibility to get them up and running.  In the absence of any written documentation, I need some help.  Although I have read through all the messages in the TAPR time-freq archive, I can't find anything that tells how to select the N divisor jumpers for 1PPS -> 100 MHz.  Also, I don't understand what the f_conf(0,1) jumpers are supposed to do.  Could someone please offer a suggestion?
