Debugging Help：
1. If the centralized controller or gateway cannot find the equipment, open the box lid and
check the LEDs for troubleshooting. Each communication terminal has a corresponding
LED. If the LED is flashing, it indicates that there is no problem with the connection.
Otherwise, check the connection.
2. If the device found is different from the actual machine, open the box lid and check the
digital display data. The digital display cyclically displays the number of IDUs and ODUs.
