Page 5: Overview
OVERVIEW The DDC-1-AC unit operates in either of two modes to bridge the divide between DALI and DMX. DALI TO DMX In this arrangement, 8-bit dimming signals received on the DALI bus are converted and output via the DMX port. When a valid DALI signal is being received the red indicator will flash continuously. -

No termination is used anywhere in the layout and the polarity of the 2-wire connections are unimportant. -

A linear bus must be formed, using very specific cable types (see below), which must be terminated at each end (the DDC-1-AC unit is internally terminated). Polarity of all connections is critical and up to 32 fixtures can be connected along the bus. -
