Hi, Peter,

Just to keep you up to date with what I hear from Rene:

Dear Fred,

First of all, I am very pleased to see the Neutrin/gamma separation 
obtained with the DEMON detectors.
Thanks for that work.

Now about the 8 channel board:
- All the pin allocations needed to be revisited.
- The input stage will allow positive, negative  single ended input, 
from Lemo or twisted flat cable, or real differential signals on 
twisted flat cable.  The options  will be realized via manual mini 
switches.
- We used a second pair of the front end FPGA to load the clock to the 
second FADC.
- The clock inputs for each FADC are now capacitively connected as 
recommended by MAXIM's

The drawings of the new scheme in going on. In could be completed in 2 
weeks, but must be checked  by you and me ( 1 week). Then sent for PCB 
production (3 weeks), The soldering of one  full unit for the TPC and 
partially a 2nd one for DEMON detectors ( We will need 2 extra ADCs)  
(1 week)

In total I expect 7 weeks from now i.e. end of November.
Or sooner may be, but not by much!

Best regards
Ren?
