AJ-DLS150K-10 Device hardware signal

Ethernet port

Ethernet ports 1 and 2 are connected in bridge mode. Wireless network port IP data transparent transmission mode.

RS232 serial port

Three RS232 serial ports (D1, D2, D3), 9PIN ZH1.5mm pitch seat, PIN pin signals are shown in the figure below. Serial port D1 has the highest priority in wireless link data transmission (higher than audio and video data, network port data, and other port data), and the lowest delay. The D2 and D3 serial ports connect to the wireless network in network IP mode. The baud rates of the three serial ports and the D2 and D3 serial transmission modes can be configured on the Web UI. The D3 serial port can be reused as the management and configuration serial port of the AJ-DLS150K-10 system AT the same time, and the system parameter configuration query and management can be performed through the AT command through the serial port.

Audio in/out interface

Audio input/output interface, 4PIN ZH1.5mm pitch seat, each PIN pin signal see the figure above. The AJ-DLS150K-10 has built-in analog audio capture codec function, and the analog audio input is Mic in by default. Analog audio output is line out and can be directly connected to the headset. The control signal is used for On/Off control of the audio input. When the AJ-DLS150K-10 point-to-point wireless communication, the audio input and output interface can be used to directly carry out point-to-point bidirectional voice communication.

Working light

Power LED: Red power indicator, usually on during normal power supply.

Node LED: Blue node indicator. When the module is configured as the central node, it is always on. When the module is configured as an A-Node, it blinks.

Link LED: indicates the wireless link status indicator. Its working status is as follows:

AJ-DLS150K-10 device application

AJ-DLS150K-10 can realize long-distance two-way wireless data communication, which can be point-to-point two-way communication and point-to-multipoint two-way communication in star networking mode. In point-to-multipoint communication, if two A-nodes need to communicate with each other through the central node, all A-nodes share the wireless bandwidth with the central node in the same wireless LAN, and the device automatically distributes the system rate evenly. Data transmission from the central node to the A-node is called downlink, and data transmission from the A-node to the central node is called uplink. In point-to-point or point-to-multipoint communication, the downlink shares the wireless working bandwidth with the uplink. When the device is shipped, the ratio of upstream speed to downstream speed is set to 4:1 by default. Therefore, if the IP Camera video data is transmitted by the device, the IP camera should be connected to the A-Node. The device dynamically adjusts the wireless transmission rate based on the service data stream. The smaller the service data stream, the longer the transmission distance under the same conditions. Therefore, when the device is used to transmit IP Camera video data, the wireless transmission distance can be improved by appropriately reducing the IP Camera video coding rate.
