  • Page 11: Power Supply

    EEPROM The reTerminal DM supports two power supply options: DC terminal and PoE port. By default, the reTerminal DM is powered through the DC terminal, while the PoE power supply is optional. This provides flexibility in power supply selection and allows for easy integration with various power sources.
  • Page 12 Note It's worth noting that the PoE module provided with the reTerminal DM is compliant with the IEEE 802.3af standard and can provide a maximum power supply of 13W. Therefore, if there is a need to connect high-power peripherals such as mobile hard disks or 4G modules, the PoE power supply may not be sufficient. In this case, it's recommended to use the DC terminal for power supply instead to ensure stable and reliable operation of the device.
