Description

SMI is the acronym for Standard Motor Interface. SMI is a bus protocol used to control SMI sunblind motors for shading. Up to 16 motors can be connected to the bus. The L-SMI 800 interface connects an SMI bus to a L‑INX, L‑ROC, or L‑DALI controller. Two SMI interface models are available.

The LSMI-800 connects a single SMI channel with up to 16 SMI motors to the EXT port of the L‑INX or L‑ROC controller. The bus power for the SMI bus is provided by the LSMI-800 interface but it is not galvanically isolated. Only SMI high voltage motors may be connected to the LSMI-800 interface.
