Somfy RS485 (SDN) 2-Way Module for Irismo 35/45

The Somfy RS485 / SDN Module for Irismo Motors is a hardwired hardware expansion designed specifically to bring bidirectional intelligence to Irismo 35 DCT and Irismo 45 DCT motorized drapery systems. This module exchanges wireless vulnerability for rock-solid, physical low-voltage serial data lines, making it the industry standard for commercial spaces, luxury builds, and complex AV projects.

Product Specifications

Integrated Flush Mount: Slid directly into the base cavity of the compact Irismo chassis, maintaining the motor's sleek profile without messy external wiring.

Dual-Source Bus Power: Power is safely managed via the host motor logic, while processing the RS485 differential data layer directly over the network bus.

Standardized RJ45 Data Ports: Utilizes industry-standard CAT-5e or higher twisted-pair cabling (terminated to TIA-568B specifications) to reliably transmit data across long distances without signal degradation.

Functional Design Highlights

Zero-Latency Response: Processes automated commands instantly, completely unaffected by RF congestion, thick concrete walls, or wireless interference.

Exact Percentage Feedback: Transmits real-time positional updates to your automation system, allowing you to script highly precise scenes (e.g., "Set window shades to 40% open").

Continuous State Mirroring: If a user manually pulls the drapery fabric using the Irismo's built-in manual override, the module instantly mirrors and updates the new position back to the central controller.

Complex Scene Grouping: Supports extensive software-defined grouping, allowing a single Irismo track to simultaneously respond to localized wall switches, zone triggers, and global building-wide overrides.
