4.2.1 Prepare to work
Before debugging the device interface, check the voltage of the power supply device
currently pre-supplying the device to ensure that the voltage value is between 12V and 55V.
After connecting the power, check whether the OLED screen has a boot interface display. For
example, when the OLED screen is not displaying, then check the power indicator status on the
LTE-LINK SE. If the power indicator is on but the screen does not display, it is scheduled to be
an OLED screen problem. On the contrary, it is the power supply problem of the equipment
power supply. After the device is powered on, the OLED screen display interface is shown as
Figure 4-1.
