NOTICE FOR CONNECTION OF POWER OR READER

When you supply power to each product, you must connect power GND to earth
GND.
SMPS (Switching Mode Power Supply) is recommended for power supply and
IDTECK's ID40WA is recommended.
If device and external reader do not use same power, to match the electric
potential, connect each GND to earth GND.
Connecting to earth GND removes potential difference between devices and
prevents malfunctions caused by surge or thunderbolt. Not connecting Earth GND
may cause communication error and malfunction such as changed system
configurations by incoming external noise and shorten the life of the product
