In the configuration software on computer, the module address, frequency channel, network ID, and key are all in decimal
display mode; The range of values of each parameter is:
Network address: 0
～
65535
Frequency channel: 0
～
80
Network ID: 0
～
255
Key: 0
～
65535
When user configures the repeater mode using the host computer, one point much be paid attention to: In the configuration
software, each parameter is in decimal, so the module address and network ID need to be converted when set it.
For example, in the configure software, if the network ID of Transmitter A is input 02, and the network ID of Receiver B is input
10, then the module address of Repeater R should be set as 522. (The address of Repeater R is 0X020A in hex, and it need to be
converted to decimal. )
11. Hardware Design
It is recommended to use a DC regulated power supply to power the module. The power supply ripple coefficient should be as
small as possible, and the module must 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 that it is within the recommended power supply voltage. If it exceeds the maximum
value, it will cause permanent damage to the module;
Please check the stability of the power supply. The voltage cannot fluctuate greatly and frequently;
When designing the power supply circuit for the module, it is often recommended to reserve more than 30% margin, so that the
whole machine can work stably for a long time;
The module should be kept as far away as possible from power supplies, transformers, high-frequency wiring and other parts
with high electromagnetic interference;
High-frequency digital wiring, high-frequency analog wiring, and power wiring must avoid the bottom of the module. If it is
