DALI communication module
Introduction
The DALI Communication Module (DCM) is a serial communication circuit designed for
controllable electronic ballasts. Ballasts are the devices used to provide the required starting
voltage and operating current for fluorescent, mercury, or other electric-discharge lamps.
The DCM supports the DALI (Digital Addressable Lighting Interface) communications
standard (IEC standard).
Main features
Figure 41. DALI communication module block diagram
The 4-bit preshift register is always active, except when in Halt mode or if the DCME bit = 0.
– 8-bit forward address register for addressing up to 64 digital ballasts
– 1.2 kHz transmission rate ±10%
– 8-bit forward and backward data registers for bi-directional communications
– Maskable interrupt
