Attention
When connecting a beacon receiver, Data OUT4/IN4 port is set to beacon/**** and configuration
data is sent from the 11 and 12 pins of SENSOR connector to the beacon receiver; however, be
aware that, at that time, the same data (the configuration data to the beacon receiver) is also led
to the 9 and 10 pins of Data IN/OUT2 connector connected inside.
For this reason, do not connect external equipment to the output of the 9 and 10 pins of the Data
IN/OUT2 connector when using the beacon receiver.
