4.2 Communication Mode
4.2.1 Point-to-Multi
Data can be sent to the specified channel.
Figure 4: Point-to-Multi
Example:
Module A: Sending Module, Address: 4369(0x11 0x11) , channel: 05(0x05) ;
Module B: Receiving Module, Address: 8738(0x22 0x22) , channel: 30(0x1E) ;
Module C: Receiving Module, Address: 13107(0x33 0x33) , channel: 30(0x1E) ;
Module D: Receiving Module, Address: 17476(0x44 0x44) , channel: 31(0x1F) ;
Data sent: 00x12x34 0x56 0x78 0x90;
If you need to send data to all modules with channel 30, the serial port needs to send data to the
module A as follows:
[0xFF 0xFF 0x1E 0x12 0x34 0x56 0x78 0x90]
 [0xFF 0xFF]: point-to-multi;
 [0x1E]: Channels requiring data reception;
 [00x12x34 0x56 0x78 0x90]: Data to be sent;
Modules B, C receive the data and send it to the serial port: [0x12 x34 0x56 0x78 0x90];
Module D can not receive data.
