Crestron C2N-HBLOCK – Multi-Type Cresnet Distribution Block

Product Overview

The Crestron C2N-HBLOCK is a parallel distribution block that terminates and distributes Cresnet network wiring from a single input point to multiple downstream devices. It accommodates three wiring types in one unit: standard 4-pin Cresnet cable, Cresnet High-Power cable, and RJ11 modular connections, making it suitable for a broad range of Cresnet installations.

Product Description

Cresnet is Crestron's proprietary 4-wire control bus that carries both power and data to keypads, sensors, and other devices throughout an installation. The C2N-HBLOCK simplifies field wiring by providing a central termination point with 16 ports across three connector formats. Diagnostic LEDs on the front panel confirm the presence of Cresnet power and verify the integrity of the Y and Z data signals, reducing troubleshooting time during commissioning. The unit ships with all required terminal block connectors. A removable mounting plate supports standalone surface mounting; up to three C2N-HBLOCK units can be rack-mounted together using the optional CNXRMAK rack mount kit (sold separately). Multiple units may be cascaded for larger installations requiring expanded port counts.

FAQs

Are all ports on the C2N-HBLOCK wired in parallel?

Yes. All 16 Cresnet ports on the C2N-HBLOCK are wired in parallel. This means any device connected to any port receives the same Cresnet power and data signals as all other connected devices.

Can the C2N-HBLOCK be rack mounted?

Yes, but a rack mount kit is required. Up to three C2N-HBLOCK units can be mounted together in a rack using the optional CNXRMAK rack mount accessory, sold separately.

How many C2N-HBLOCK units can be cascaded?

Multiple units may be cascaded, limited by the total Cresnet power budget of the connected power supply. Consult the Cresnet power supply specifications and device load requirements to determine the maximum number of devices per network segment.
