Common questions
What does the SDN Data Hub V2 do?
It is an SDN bus distribution device that adds 5 device ports to an SDN bus line. Somfy calls the Data Hub V2 the backbone of its SDN Connect range of products.
How is the Data Hub V2 powered?
The hub draws power from the motors when two or more motors connect to its device ports. With fewer than two motors connected, it needs 24V DC bus power.
How many keypads or receivers can it power?
Somfy rates the Data Hub V2 to power 3 keypads or 1 RTS receiver from its ports. Plan a separate bus supply if a hub needs to carry more devices than that.
What connectors and cable runs does it support?
It uses RJ45 connectors, with wiring stubs up to 200 ft. The compatible parts on this page include SDN low-voltage power and data cable (9020126) and RJ9 to RJ45 data cables (9018542, 9018543).
What helps with commissioning and install?
Bus segment status LEDs show power, activity and end of line. A sequence button tests motor operation at the hub, and a mounting clip speeds install and removal. Somfy rates it IP 20, Class I.
