The switch SW501 is the reset switch of the RL78/I1A DC/DC LED Control
Evaluation Board. It can be used to reset operation during on-board debugging or
during normal operation mode.
External power is supplied by connecting a regulated 5V DC to the jack
connector CN1.
The operation of the board is as follows:
- External supply only (The board can only be operated as stand alone only, no
USB power connection).
Or
- External supply and USB power (This configuration should be used when the
user intends to use On-Board debugging, flash programming or virtual UART
communication via the µPD78F0730 78K0 8-bit microcontroller).
CN2 is the connector for DALI interface. CN2 is a 2-way connector to enable
communication with a DALI master via the DALI communication protocol.
CN3 is the connector for DMX512 interface. CN3 is a 3-way connector to enable
communication with a DMX512 master via the DMX512 communication protocol.
InfraRed (IR) detector U2 can be used to enable IR communication between a
controller device and the RL78/I1A. The controller device can send commands to
the RL78/I1A microcontroller using the IR communication protocol.
