| Pin No. | Name | Description |
|---|---|---|
| 1 | RS232 | RS232 interface |
| 2 | 485_A | To connect the end A of other RS485 device |
| 3 | 485_B | To connect the end B of other RS485 device |
| 4 | GND | Ground |
| 5 | VCC | Power supply， 8~28V,12V or 24V is recommended |
| 6 | PWR | Power indicator |
| 7 | WORK | 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; |
| 8 | NET | 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; |
