Communication between programmable control gear and other DALI devices (sensors, control panels or other
peripherals) takes place via two cables and is two-way, enabling dimming, configuration and consultation commands
to be sent.
By selecting this method, the user can choose between a logarithmic or linear dimming curve.
All the information relating to this dimming system is explained in the DALI standard in line with which the eSMART
technology drivers have been designed.
6.2. 1-10V / 0-10V mode
This dimming system is able to vary the light flow by means of an analogue control signal that reaches the drivers
via an additional two-wire control line, whose positive and negative polarity must be observed when making the
connection.
This one-way system, in which the control information only flows from the controller towards the control gear, is not
addressable, given that every device connected by cable to the control line reacts to a set point.
The analogue control signal is a continuous voltage level within a range from 0V to 10V. This signal can be obtained
directly from an active control device (analogue control cards or power supply sources) or indirectly from a passive
control device (variable resistance or potentiometer) through which the output current generated by the devices in
their control terminals circulates.
