- Technical Parameter
The KH-N800 series has achieved decentralized and long-distance communication between a large number of nodes without a central hub. All nodes can communicate with each other independently without interfering with each other, solving technical problems such as large-scale dense channel access, wireless transmission, dynamic networking and flexible reconfiguration of unmanned clusters, and real-time collaboration. It enables the swarm network to have the networking capabilities of biological swarm behavior, autonomous networking driven by scenarios, flexible reconfiguration and intelligent collaboration.
The self-organizing network module of KH-N800 has the ability to connect a large number of large-scale nodes, 16-hop self-organizing network coverage capability, ultra-low latency, and is simple and easy to use. It can be applied to scenarios such as swarm unmanned aircraft, Internet of Things, data link, remote control, data collection, artificial intelligence, and individual equipment.
The module supports two working modes: transparent transmission mode and configuration mode. Users can configure the MODE0 and MODE1 pins of the module to make it operate in the corresponding mode.
| Through-transmission mode | configuration mode | configuration mode | Through-transmission mode |
MODE0 | 0 | 1 | 0 | 1 |
MODE1 | 0 | 0 | 1 | 1 |
When the module is in transparent transmission mode, it will not respond to configuration commands. When it receives serial port data, it will transmit it to the air interface. When it receives signals from the air interface, it will output data to the serial port.
When the module is in configuration mode, it will only respond to configuration commands and will not transmit the received serial port data to the air interface. When it receives signals from the air interface, it will not output data to the serial port. In configuration mode, the serial port baud rate is fixed at 9600, with 8 data bits, 1 stop bit, and no parity bit.
The configuration status indication signal (ACK) of the module indicates the current configuration status. When it outputs a low voltage, it means that the module is currently in initialization or configuration, and will not respond to other configuration commands. When the module outputs a high voltage, it means that the module has completed initialization or configuration. After powering on the module, one should wait for the ACK signal to rise before proceeding with subsequent configuration or data transmission. After configuring the module, one should also wait for the ACK signal to rise before proceeding with subsequent configuration or data transmission.
