    keyword=New instruction to synchronize running L-arm and R-arm

    For the instruction in log 268508, it is controlled by MLU file and needs
    to download trigger settings. This new instruction is about how to plug
    or unplug cables in the counting house and it does not need MLU file any
    more.

    In the middle room of Hall-A counting house, find the frame closest to
    the door. At the bottom of this frame, you can find a port labled by "run
    gate to RHRS". There are also 2 BCM cables, labled by "seperate" and
    "synch.".

    (a) synchronize running L-arm and R-arm
    plug the cable "synch." to the port "run gate to RHRS", this will
    synchronize running L-arm and R-arm. Start R-arm DAQ at first, then start
    L-arm DAQ; while end L-arm DAQ at first, then end L-arm DAQ.

    (b) run L-arm and R-arm seperately
    plug the cabel "seperate" to the port "run gate to RHRS", this will
    run L-arm and R-arm seperately.
