C2N-HBLOCK Ports
The C2N-HBLOCK contains three types of ports that are connected in
parallel. The eight 3.5mm, 4-pin connectors (labeled

) and the five 5mm, 4-pin connectors (labeled

,

,

and
E
) are
used to connect the C2N-HBLOCK to other four-wire Cresnet devices.
The three 6-pin RJ11 modular ports (labeled
a
,
b
and
c
)
are used to
connect the C2N-HBLOCK to modular devices in the Cresnet system.
Only one port (any of the three types) is used as an input source and the
remaining ports are used as outputs.
CAUTION: Do not connect or daisy-chain more than one power
input (power pack or power supply) to the C2N-HBLOCK. Multiple
power inputs may damage one or more power packs and/or power
supplies.
NOTE:
When using the C2N-HBLOCK to output power to other
devices, do not exceed the maximum capacity of the power pack or
power supply. Calculate and add the total power requirements for all
devices drawing power from the C2N-HBLOCK. If necessary, use
additional C2N-HBLOCKs and power packs or power supplies.
C2N-HBLOCK Indicators
There are three LED indicators located on the C2N-HBLOCK front
panel. The LEDs are described in the next three paragraphs.
