    keyword=R-HRS: Little change on S1 TDC cabling

    I found that S1 TDC signals after DIS is actually not a good digtal shape, so I have to put the cable into a 'ECL programable width FanOut', whic normalizes the signals, and then send the signals into a delay module at slot 10 on crate 1, which actually does not put any delay values in and is just used as a splitter. Two output from this delay module go into TDC modules on FB, and scaler respectively. And now the flat cable #8 is used for S1 TDC to FB, because the previous one is kind of old and loose.
