sensor and this evaluation module.
Set the serial communication method by using the communication mode selection switches on the
EM7162 module before connecting the USB cable or the power supply.
Caution‼ Before changing the serial communication setting, be sure to turn off the power
switch (SW1) by setting it to the lower position as shown in Fig. 2.
