Basic Functions

Wireless 4G Communication: After configuring network parameters via the RS485 configuration software and successfully establishing a connection with the server, the device proceeds to transmit data.

Downlink LoRa Wireless Communication: After configuring the relevant data acquisition parameters via the RS485 channel, the device performs rapid reading of data from connected equipment.

RS485 Port: The device enables communication with electricity meters via the RS485 interface while simultaneously maintaining wireless communication capabilities. This achieves true dual-channel simultaneous communication without mutual interference; the RS485 port communication baud rate is 2400 bps.

Integrated Data Resend Mechanism: The power gateway terminal features an internal mechanism for detecting and resending missing data, ensuring timely retransmission to enhance data integrity and stability.

Remote Software Updates: This power gateway terminal supports remote software upgrades and updates via 4G connectivity, thereby reducing the costs associated with system updates.
