Up to twenty-four 3860 CCMs can be daisy-chained together for charging and
communications. To daisy chain two or more groups of four CCMs requires:
!
one 25-pin, male-to-female, straight-through RS-232 cable per group of coupled
CCMs
and
!
one power supply per group of coupled CCMs.
Depending on how close together you place the CCMs, the cables can be from 1-foot to 10-
feet long.
