Wireless Data Transmitter Overview:
HNC2 self-organizing Mesh network data link radio enables the
centerless long range communication between large-scale nodes, each
node can communicate with others independently without interfering,
supports large-scale dense node access to wireless transmission,
dynamic networking and flexible reorganization, supports
full-multiplexing communication, the nodes can send data and
receive the data of all other nodes synchronously without
interfering with each other. Even without center hub, any node can
also achieve the interoperability with all other nodes in the
network without interfering with each other.

self-test, light on when transmitting data |
| CA-LED | Blue, interference indicator led, briefly lit during power on
self-test, frequently lit in configuration mode. In transparent
transmission mode: When the light is on, there is interference with
the air interface, and the brighter the light, the stronger the
interference. |
Dip Switch
The dip switch can control the operating mode of the radio.
Operating Modes
The radio supports two modes:
- Configuration Mode
Data Transparent Transmission Mode
Configuration Mode
When HNC2 is in configuration mode, Uart1 will only respond to
configuration commands and will not transmit received serial data
to the air interface, nor will it output data to the serial port
when receiving signals from the air interface. In configuration
mode, the serial port baud rate is fixed at 9600, with 8 data bits,
1 stop bit, and no parity check bits.
Only local configuration parameters can be modified.
Transparent Transmission Mode
In transparent mode, Uart1 will configure parameters if it receives
serial data as a configuration packet; If the received serial data
is not a configuration packet, it will be transmitted to the air
interface, and the signal received from the air interface will be
ejected to the serial port.
Both local and remote parameter configurations are supported.
