3.1.4 Virtual UART Mode
The
RL78/I1A DC/DC LED Control Evaluation Board
supports Virtual UART mode
via the µPD78F0730 78K0 8-bit microcontroller. Switch SW2 should be set as
shown in the table below:
Bits

8 ON
SW2, Virtual UART Mode
Table 4:
* When DALI or DMX512 communication is to be used, bits 1 and 2 of switch SW2
should both be set to ON position.
3.2 Configuration Switch SW1
The switch SW1 selects the lighting communication protocol to be used by the
RL78/I1A DC/DC LED Control Evaluation Board
.
When using DALI or DMX512 communication, please don’t forget to set bits 1
and 2 of switch SW2 to ON position.

3.3 Configuration Switch SW3
The switch SW3 selects the IR remote control channel. Two different channels
can be selected on the
RL78/I1A DC/DC LED Control Evaluation Board
, CH1
corresponds to a 0x5AA5 data code, and CH2 to a 0xDA25 data code.
