View source for ToDo List of DAQ change

Currently the DAQ is running in triple-coincident mode, and all triggers (T1,T2,T3,T4) are sent to BigBite weldment to form T5 
(which is T1&T3), by using RG8 long cables, and the Trigger Supervisor on a CAMAC crate in that weldment creates a L1A signal 
of T1~T7. Two long RG8 cables send the L1A signal back to two HRSs. L1A is retimed using strobe signals (S1.Or.S2) on both arms
and the new RT signals are sent into their TM module to create ADC gate and TDC STOP signals.

DAQ will still be running with current configuration -> One CODA, Two-HRSs taking Electrons simultaneously each run. But there 
are some minimum change:
 
 1, SRC were taking Protons on R-HRS and Electron ons L-HRS by forming a coincident of T1&T3, hence different delay values of 
 L1A were set to compromise the speed difference of Prontons and Electrons. We don't need the T5 and T&T3 are both for electrons
 with same kinematics, so the delay times are needed to be changed. Set the delay values of two L1A signals by matching the 
 strobe signals (or called retiming signals). In general, L1A has to be at least 30ns earlier than strobe signal. There two 
 delay modules on each arm to delay L1A signals: Crate#1 Slot#20 for Right, and Crate#2 Slot#17 for Left.(by Zhihong)

 2, After the retimed L1A creating ADC gates and TDC STOP, check that all ADC signals have to be in the gate. The width of ADC
 gate currently is set to 270ns and the ADC signals have to come at least 50ns later than the leading edge of the gate. 
 TDC STOP by designing should be enough so we don't have to change anything on it. (by Zhihong)

 3, Complete scalers on RHRS and make sure all scalers on LHRS are working properly. (by David)
