…Do not require a separate shielded communication cables, able to construct with general cable or cable wiring.
…When constructing the cable, able to use the 5C cable (3C-L/N/E, 2C-DALI). Also without installing a separate communication
  line, construction is possible.
…No need to distinguish between the polarity of communication line.

 The LDM w/ Occ is the Module that performs the DALI Control through DALI Protocol which is connected to DALI Master.
 The DALI Master is connected to the Full 2-Wire System with no polarity. This is the indispensable device that enables the On/Off, Dimming, Schedule, Pattern, Scene, Individual, and Group Control for 64 EA. of LED DALI Modules for LED Fixtures. This device is made with the existing LDM that is built-in wish motion detecting sensor(infrared sensor) to perform the Individual, Group, On/Off and Min/Max Dimming Control. Especially when it is introduced into the coneference room, it is automatically turned On/Off the LED Lighting to perform the Energy Saving Effect.
 Also, this device has it's own function(Hardware Min. Max.) to easily interface with LED Fixtures.
