Wi-Fi 2. Ethernet cable 3. LTE Cellular network (optional, only available when the LTE modem and adapter board is correctly inserted); 4. The IOTGateway supports Wi-Fi Mesh Networking, which means one IOTGateway can connect to the internet via another IOTGateway. In this mode the master IOTGateway can share its LTE connection to a number of other IOTGateways connected over Wi-Fi 5.2Power supply interface There are two interfaces for power supply: macro USB interface and external +12​V​DC Supply ●The IOTGateway can be powered directly through the TTL Modbus connector. The external supply range is from +6VDC to +18VDC (details of the connector pinout can be found in section 7) ■The TTL Modbus connector also provides an isolated power fail detection circuit to provide an alert when the main power fails and the IOTGateway is powered from the external battery backup supply. ●Macro USB power supply, powered by the 5V/1A DC. Warning: ​The IOT can only use one of the two power supplies at the same time. Please don’t insert two power supplies at the same time, otherwise the IOTGateway may be damaged.

The reset button can be pressed using a suitable tool such as paperclip. a)If the RESET button is pressed for less than 30 seconds a gateway REBOOT is initiated. The IOTGateway takes approximately -1 minute to reestablish a network connection and come back online after a reset. b)If the RESET button is pressed for more than 30 seconds a factory RESET is initiated. The factory reset erases all network credentials in addition to cleaning up local files and logs on the device. .
