Summary

• Somfy SDN Data Hub (1870262), a five-port Somfy Digital Network bus distribution device designed to expand RS485 communication and device connections in compatible motorized shade, blind, curtain, and drapery automation systems.
• The Somfy Data Hub adds five RJ45 device ports to an existing SDN bus line, allowing compatible Somfy motors, wall keypads, RTS receivers, and automation interface devices to connect to the same wired control network.
• Each device port supports wiring branches up to 200 feet in accordance with Somfy's 2019 Data Hub documentation. The hub receives its operating power from the SDN bus and consumes approximately 10mA, equivalent to one SDN power unit.
• Integrated LED indicators display bus power, communication activity, idle status, and end-of-line information. The unit also includes miswire protection and automatic bus segment termination to support reliable installation and operation.
• Listing is for the Somfy SDN Data Hub (1870262) only, does not include any Somfy motors, SDN network cables, external power supplies, installation screws, instructions, or original box. Please review all photos for the exact item, condition, and components included.
• This item was sourced from a new, uncommissioned equipment cabinet that was dismantled prior to being placed into service.

Product Description

• The Somfy SDN Data Hub, manufacturer part number 1870262, is a wired bus distribution accessory designed for Somfy Digital Network (SDN) motorized window covering installations.
• Somfy Digital Network is an RS485-based control system used to connect compatible motorized shades, blinds, curtains, draperies, wall controls, receivers, and automation equipment through a shared communication infrastructure.
• The Data Hub adds five device connection ports to an existing SDN bus segment, providing convenient distribution points for multiple compatible devices without requiring a separate home-run connection from each device to the main control system.
• In addition to its five device ports, the hub provides dedicated SDN Bus In and SDN Bus Out connections for integration into the main network backbone. Its RJ45 modular connectors simplify wiring and support structured SDN network installations.
• According to Somfy's January 2019 Data Hub specifications, each device port supports a wiring branch of up to 200 feet. Actual system wiring must follow the applicable Somfy design rules, cable specifications, network power limits, and bus topology requirements.
• The hub is powered through the Somfy Digital Network bus and consumes one SDN power unit, approximately 10mA. It does not require a separate dedicated AC power connection when the SDN network is appropriately powered.
• Four integrated status indicators provide helpful information for system commissioning and troubleshooting. The green Power indicator identifies the presence of bus power, while the Activity and Idle indicators show communication status. A yellow End indicator identifies end-of-line status.
• Automatic segment termination helps maintain proper RS485 communication conditions, while built-in miswire protection helps protect connected network components from certain wiring errors.
• The Data Hub is compatible with appropriately designed Somfy SDN installations that include devices such as Sonesse RS485 motors, compatible Somfy keypads, RTS receiver interfaces, and Somfy Connect products.
• The device is suitable for standalone SDN installations and systems integrated into larger building automation platforms through the appropriate Somfy control and integration equipment.
• The white ABS housing measures approximately 4.88 inches long, 2.24 inches wide, and 0.90 inches high, making the hub suitable for installation in protected indoor locations where compact network distribution is required.
• The Somfy 1870262 is a passive SDN distribution and communication accessory. It is not a standalone Ethernet router, Wi-Fi controller, motor power supply, or IP gateway. Ethernet or third-party automation integration requires compatible separate Somfy interface equipment.
• This original Somfy SDN Data Hub is useful for replacement installations, system expansion, maintenance of existing wired Somfy networks, and professional motorized window covering projects.
