AJ-DLS22K-2, 5 Application description

AJ-DLS22K-2, 5 can realize long-distance two-way wireless data communication, can be point-to-point two-way communication, can also be point-to-multipoint star networking mode two-way communication. 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.

AJ-DLS22K-2, 5 When the device is shipped, the default Settings are:

> Central node, IP address: 192.168.1.11

> A-Node, IP address: 192.168.1.12. If there are multiple A-Nodes, the IP address is set to 192.168.1.12, 192.168.1.13, 192.168.1.14, in sequence......

> Serial port baud rate: 115200, data bit 8, stop bit 1, no verification mode.

The IP addresses of the upper computers at both ends that are connected wirelessly through AJ-DLS22K-2 and 5 must be set in the same network segment as AJ-DLS22K-2 and 5, avoiding the IP addresses of AJ-DLS22K-2 and 5. It can also form a network segment (different from that of the AJ-DLS22K-2 and 5 devices).

AJ-DLS22K-2, 5 The device provides Web UI for parameter configuration.
