In the configuration on computer, the module address, frequency channel, network ID, and key are all in decimal mode.
The range of values of each parameter is:
Network address: 0-65535
Frequency channel: 0-83
Network ID: 0-255
Key: 0-65535
When the user configures the repeater mode using the host computer, special attention must be paid. Since the
parameters are in decimal mode in the host computer, the module address and network ID need to be converted into
hexadecimal. For example, if the network ID input by the transmitting end A is 02, and the network ID input by the
receiving end B is 10, when the repeater end R sets the module address, the hexadecimal value 0X020A is converted into
the decimal value 522 as the repeater end R. Module address. That is, the module address value of the repeater terminal
R is 522 at this time.
10 Hardware design
It is recommended to use a DC stabilized power supply. The power supply ripple factor is as small as possible,
and the module needs to be reliably grounded.；
Please pay attention to the correct connection of the positive and negative poles of the power supply.
Reverse connection may cause permanent damage to the module；
Please check the power supply to ensure it is within the recommended voltage otherwise when it exceeds the
maximum value the module will be permanently damaged；
Please check the stability of the power supply, the voltage can not be fluctuated frequently；
When designing the power supply circuit for the module, it is often recommended to reserve more than 30%
of the margin, so the whole machine is beneficial for long-term stable operation.；
