Dimming control interface

This board supported 5 types of dimming control interfaces. This section describes each dimming control
interface.
DALI-2 protocol communication interface
DMX512 protocol communication interface ( also available as RDM-DMX )
SMbus/PMbus protocol communication interface
IR remote control interface
3 ch. analog volume control interface (for standalone evaluation)
2.4.2.1 DALI-2 protocol communication interface
It is equipped with connector CN2 for DALI protocol communication interface and enables communication
with the DALI Control device. In order to enable cascading of connectors, the signals printed on silk are
connected as the same signal in the front (1st stage) and back (2nd stage) of the connector.
