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.
