RS232 interface

To connect the end A of other RS485 device

To connect the end B of other RS485 device

Ground

Power supply， 8~28V,12V or 24V is recommended

Power indicator

Blue: Receipt transceiver pin, when the network receives data or the serial port receives data (50ms high/10ms low)

Green: device status indication pin, Low: The device is powered on to search for a SIM card 1800ms low, 200ms high: The device checks the correct SIM card and is attaching to the network; High: The device is attached to the network successfully;

Green: Socket A link connection status indication pin High: Socket A is successfully connected to the network server; Low: Socket A is not successfully connected to the network server;

Blue: Socket B link connection status indication pin High: Socket B is successfullyconnected to the network server; Low: Socket B is not successfully connected to the network server;

DC adaptor，8~28V, 12V or 24V is recommended

Dip switch（downward，reset）

Dip switchAfter the radio is powered on normally, the Restore dials from top to bottom, and continues down for 3~10S, then from bottom to top. After the process is completed normally, the radio parameters will be restored to the factory settings and restartedimmediately.
