2.4.7 Board Recognition, Connection, and Disconnection

● Board (device) recognition is executed when DLL is activated (when library for driver I/F is activated).
● A device connected after the application is activated is not recognized.
● A device disconnected after the application is activated cannot be controlled.
→ In any of the cases above, a USB communication error occurs, resulting in function failure. (Returns a
value other than "0")
In such case, confirm safety and quit the application immediately.
Then, turn OFF the power of the device, and connect again.
● Arbitrarily connecting the USB while the application is running affects the application's USB
communication.
→ A communication failure will occur.
● When mounting or demounting a board (device), wait for more than 5 seconds after the connection
before using (executing communication).
→ USB may not be recognized (activated) normally if it is reconnected too soon after disconnection.
