Crestron CAEN-BLOCK-CENCN-2-POE – Ethernet to Cresnet Bridge

Product Overview

The Crestron CAEN-BLOCK-CENCN-2-POE is an Ethernet-to-Cresnet bridge module designed for direct installation inside CAEN and CAENIB automation enclosures. It delivers CEN-CN-2 class Cresnet control functionality with Power over Ethernet (PoE) input, eliminating the need for a separate 24V power supply in the enclosure. This module enables IP-based management of Cresnet devices from any network-connected Crestron control system.

Product Description

The CAEN-BLOCK-CENCN-2-POE bridges TCP/IP Ethernet control commands to the Cresnet bus, allowing a network-connected Crestron processor to address Cresnet keypads, occupancy sensors, dimmers, and other Cresnet devices without a dedicated RS-232 or direct wired path. The module receives its operating power via IEEE 802.3af PoE from the network switch, reducing wiring complexity inside the enclosure. It is form-factor matched to CAEN and CAENIB enclosures, mounting cleanly alongside other CAEN-BLOCK modules. Both residential and commercial Crestron installations benefit from this module wherever Cresnet infrastructure must be managed over an IP network.

Frequently Asked Questions

Q: Does the CAEN-BLOCK-CENCN-2-POE require a separate power supply inside the enclosure?
A: No. The module is powered entirely via IEEE 802.3af PoE from the network switch, so no additional 24V power supply is needed for this module.

Q: Which enclosures is the CAEN-BLOCK-CENCN-2-POE compatible with?
A: It is designed for use inside Crestron CAEN and CAENIB automation enclosures and is form-factor matched to those products.

Q: Can this module replace a standalone CEN-CN-2 Cresnet controller?
A: Yes. The CAEN-BLOCK-CENCN-2-POE provides CEN-CN-2 class Cresnet controller functionality, bridging Ethernet control commands to the Cresnet bus for connected devices.
