    Front View

    ① Power Cables - power supply input line, red is VDD, black is GND

    ② Data UART Port (GND, Rx, Tx) – 3.3V TTL

    ③ Link Status Indicator - When the device works as an access node, if the connection with the central node is normal, the indicator will be always on. When the device works as a central node, this indicator is off.

    ④ Micro USB Port - For device software maintenance.

    ⑤ Indicator (Red) for Power - Always on during normal operation.

    ⑥ Indicator for Ethernet Port 2 – Flashes according to the data flow when works normally.

    ⑦ Ethernet Port 2 (RN, RP, TN, TP) - Ethernet port 1 and 2 are internally bridged.

    ⑧ Indicator for Ethernet Port 1 – Flashes according to the data flow when works normally.

    ⑨ Ethernet Port 1 (RP, RN, TP, TN) - Ethernet port 1 and 2 are internally bridged.

    ② Air Inlet - for the cooling fan

    ③ ANT2 Port - Auxiliary antenna, works as auxiliary receiving, NO transmitting.

    ④ ANT1 Port – Main antenna, work mode is TDD transmitting/receiving.


    Serial Communication

    Please use an USB to TTL serial 3.3V adapter cable to connect your computer and the device (TTL)

    On your serial debugging tool please select the correct serial port, and other settings are as below:

    Baud: 115200bps

    Data: 8 Bits

    Parity: None

    Stop: 1 Bit


    Application Notes

    It can realize long-distance two-way wireless communication, point-to-point two-way communication, or point-to-multipoint two-way communication. In point-to-multipoint communication, if the communication between two access nodes needs to be transferred through the central node, each node is in the same wireless local area network, and all access nodes communicate with the central node to share the wireless bandwidth, and the device automatically allocate the system rate evenly. The data transmission from the central node to the access node is called downlink, and the data transmission from the access node to the central node is called uplink. In point-to-point or point-to-multipoint communication, the downlink and uplink share the wireless bandwidth. When the device is shipped, the default setting is the ratio of uplink rate to downlink rate = 4:1. Therefore, if using the device to transmit IP Camera video, the IP camera should be connected to the access node. The device will automatically and dynamically adjust the wireless transmission rate according to the carried data stream. When the amount of carried data is smaller, the transmission distance will be longer under the same conditions. Therefore, when using the device to transmit IP Camera video, it is possible to increase the wireless transmission distance by appropriately reducing the IP Camera video encoding bit rate.
