			We will install everything in the hall and set all software by the end of next week (before Sergey B. vacation),
			communication between Ben's machine and crates in the hall will be established similarly to clastrig2;

			next week 7 v1495's will be moved to the hall

			cabling will be done then

			communication to FC still must be tested: will ask Chris

New page

present: Sergey Boyarinov, Ben Raydo

clock 15ns, propagation time 65-90ns, including hodoscope
(15ns come from passing data between v1495 boards)

discr width 7-43ns

inputs to v1495: common delay for hodoscope with 5ns step

need matching table between hodoscope and calorimeter !!!

photon and electron triggers in parallel: may increase total trigger timing

scalers will be implemented to all inputs, and some trigger results, resolution about 25MHz;
preferabley deadtimeless, but can be with dead timne like clas trigger scalers;
readout every 10 seconds, 32 bit registers but probably less bit actual count
