DSI Explained

DSI (Digital Serial Interface) is a proprietary protocol for controlling lighting ballasts which was developed by Tridonic. Whilst it is a digital protocol and it's wiring is similar to that of DALI and Analogue control however unlike DALI all of the ballasts or light fittings connected to the DSI channel behave identically. It's advantage is that it provides simple digital control of a group of lights with the whole group being able to be turned on, off or dimmed together.

The mySmart Sensor range of DD detectors with lux level sensing are all able to control DSI light fittings easily and quickly for absence/presence detection as well as ambient light level harvesting. mySmart Sensors by CP Electronics are available in a wide range of detectors to control DSI lighting. The DD range of DSI Sensors suit a wide range of applications and projects and are easily programmable using either the UHS5 or UNLCDHS Professional Commisioning Handsets.
