3. Connect the cable’s other connector to the host computer’s serial (COMM) port.
Daisy-Chaining Two or More CCMs
Up to twenty-four 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
!
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.
Figure 2-15. Daisy-Chaining Multiple CCMs
To chain the CCMs:
1. Couple the CCMs as directed in the section Coupling CCMs.
2. In the first coupled section, connect the serial cable to the left-most CCM.
3. Connect the RS-232 cable’s (male or female) DB-25 connector in the serial port of
the right-most CCM in the first coupling.
4. Connect the (male or female) DB-25 in the serial port of the left-most CCM in the
second coupling.
