Crestron CNTBLOCK – Cresnet Distribution Block

Product Overview

The Crestron CNTBLOCK is a Cresnet distribution block that simplifies wiring of Cresnet devices in a Crestron control system. It provides multiple Cresnet connection points from a single source, reducing wiring complexity in larger installations.

Product Description

Cresnet is Crestron's proprietary four-wire control bus, carrying power and data to peripheral devices throughout an installation. The CNTBLOCK provides a convenient junction point that distributes Cresnet signals to multiple device branches from a single Cresnet port on the control processor or rack equipment. This is particularly useful in equipment rack builds, AV rooms, and distributed installations where multiple Cresnet devices need to be wired from a central location without running individual home runs back to the processor.

Key Features

• Cresnet distribution block for multi-device Cresnet wiring
• Multiple Cresnet output connections from a single input source
• Simplifies wiring in rack-mount and distributed AV installations
• Reduces the need for individual home-run Cresnet connections
• Compact form for use in equipment racks and enclosures

Typical Applications

• AV equipment rack builds with multiple Cresnet peripherals
• Distributed audio/video systems with multiple Cresnet zones
• Conference room AV control with several Cresnet devices
• Residential whole-home automation racks

Technical Specifications

• Protocol: Cresnet
• Function: Distribution block (multi-output)

FAQs

How many Cresnet devices can I connect to the CNTBLOCK?

Refer to the Crestron CNTBLOCK datasheet for the exact port count and Cresnet power budget requirements per installation.

Does the CNTBLOCK require its own power supply?

The CNTBLOCK passes power from the Cresnet source. Verify that the Cresnet bus power budget covers all connected devices. Additional Cresnet power supplies may be needed for large installations. See creationnetworks.net for compatible accessories.
