CNHBLOCK Ports
The CNHBLOCK contains three types of ports that are connected in parallel. The eight
3.5mm, 4-pin connectors (labeled 1, 2, 3, 4, 5, 6, 7 and 8) and the five 5mm, 4-pin connectors
(labeled A, B, C, D and E) are used to connect the CNHBLOCK to other Cresnet four-wire
devices. The three 6-pin, 6-position RJ11 modular ports (labeled a, b and c) are used to
connect the CNHBLOCK 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 CNHBLOCK. Multiple power inputs may damage one or more
power packs and/or power supplies.
NOTE: When using the CNHBLOCK 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 CNHBLOCK. If necessary, use
additional CNHBLOCKs and power packs or power supplies.
CNHBLOCK Indicators
There are three LED indicators located on the CNHBLOCK front panel. The LEDs are
described in the paragraphs on the next page.
