3.3.2 Steps when communication is used

This product has the DALI communication and DMX512 communication circuits. By using the serial interface

UART6/DALI incorporated on the 78K0/IB2, slave operation of DALI communication and DMX512 communication can be

achieved. To use communication, connection is required according to the communication method. This section describes

the steps in which the lighting communication master evaluation board (EZ-0008) is used.

<1> Make sure that the power supply of the main unit is off, and connect the load to the LED output connector.

<2> Connect the main unit and EZ-0008 with a cable. Connection varies depending on the communication method.

For details, refer to Figure 3-3.

<3> Adjust the DALI/DMX512 changeover switch to the communication to be used.

<4> Connect the EZ-0008 to the PC.

<5> Connect the power cable to the main unit, and connect it to the receptacle.

<6> Turn the power switch of the main unit to the ON position to supply AC power. The program written to the

microcontroller starts to operate.

Caution For programs created with the Applilet EZ for HCD, auto tuning operation is required before

performing the selected dimming operation. Parameters of preview control are obtained in auto

tuning, so voltage is applied to the load up to the preset current.

To start auto tuning, press the dimming switch (SW1). When auto tuning is complete,

communication operation starts.

<7> Start the DALI master controller GUI or DMX512 master controller GUI on the PC to start evaluation.

<8> When the evaluation is finished, turn the power switch of the main unit to the OFF position to stop the AC

power supply.
