Chapter 9 PC Configuration Instructions

The figure below shows the display interface of the host computer for E22-400T30S configuration. Users can switch to the
command mode through M0 and M1, and quickly configure and read parameters on the host computer.

In configuring the upper computer, the module address, frequency channel, network ID, and key are all in decimal display mode;
the value range of each parameter:
Network address: 0
～
65535
Frequency channel: 0~83
Network ID: 0~255
Key: 0~65535

When using the host computer to configure the relay mode, the user needs to pay special attention. Since the parameters in the
host computer are in decimal display mode, the module address and network ID need to be converted when filling in;
For example, the network ID input by the transmitter A is 02, and the network ID input by the receiver B is 10, then when the
relay terminal R sets the module address, convert the hexadecimal value 0X020A to the decimal value 522 and fill it in as the
relay terminal R module address;
That is to say, the module address value that the relay terminal R needs to fill in at this time is 522.
Chapter 10 Hardware Design

It is recommended to use a DC regulated power supply to power the module. The ripple coefficient of the power supply 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, such as 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, and having
