    keyword=HRS EDTMs Configured as Slaves

    Now that the BigBite EDTM module is acting as the master module, I have 
    sent a copy of the back output signal to the left and right HRS's.  With
    David's help we measured the delay between the back and front output's on
    each module in both HRS's.  This delay turns out to be about 120 ns for 
    all four modules.  
    
    On each HRS, I used a fan-out to produce two copies to go into the back 
    input for the S1 and S2 EDTM.  I verified that both were working.  On the
    left HRS, I then used a front output on the S2 EDTM to generate the 
    pulser for the S2m Amp module, which sends the signal to splitter box on 
    S2m and eventually to the discriminator for each channel.
    
    Unfortunately, I do not have a S2m Amp module for the R-HRS, but I would 
    like to try a PS 776 10x amplifier to see if that will work.
    
    Tomorrow, I will try to set the relative delays for the modules to
    produce a S1/S2m coincidence on each arm to mimic the singles triggers.
