2.3 Connection
HCS-4100MC/50 has 2 outlet (6P-DIN) trunk-line cable
sockets for connecting to voting units. Voting units are
equipped with a cable with a standard 6P-DIN male
connector.
When connecting the CMU to the voting units, just
connect the male connector of the first unit to the
socket of the CMU.
For a longer distance between the voting unit and the
CMU/EMU, a CPL6PS extension cable can be used.
One end of this cable is equipped with a 6P-DIN male
connector; the opposite end is equipped with a female
connector. Just connect the female connector of the
cable to the voting unit, and connect the male
connector to the output of the main unit.
Figure 2.5 Voting unit connected to the CMU or the EMU
For “daisy chain - closed loop” connection, just connect
the last voting unit back to the CMU via a CBL6PP
extension cable (both ends of this cable are equipped
with a 6P-DIN male connector). In Large-Scale Voting
System, the congress main unit can realize a “Closed
Loop - Daisy Chain” connection, but only one –
extension units do not offer this feature.

topology
One HCS-4100MC/50 contains 2x 6P-DIN outlet
trunk-line cable connectors, and each outlet connector
can output 60W. Since the power capacity of a 6P-DIN
interface is limited, it must be ensured that, during the
installation, the sum of the total power consumption of
all the congress units connected to every single
6P-DIN interface plus the power loss in the extension
cables does not surpass the power limit of each
6P-DIN interface. Otherwise the system will not work
properly or automatic protection will occur (see
connection principles).
