4.2 Connection between the CMU and the contribution units
All contribution units of HCS-3900 system adopt
dedicated 6-pin cable and are daisy-chained, which
makes the installation handy and effortless.
Connect the first unit to the outlet connector of the CMU,
and following connect the plug of the cable of the second
unit to the socket of the first unit. Proceed one by one in a
series configuration. CBL6PS extension cables can be
used between contribution units and the CMU. As shown
in the figure 4.1.
