5.6 Broadcast address

When the module receives commands in non MODBUS format, it will send the received data as transparent
data.
For example: set the address of module a to 0xFFFF and the channel to 0x04.
When module a is used as the transmitter (the same mode, transparent transmission mode), all
receiving modules under 0x04 channel can receive data to achieve the purpose of broadcasting.

5.7 Listening address

For example: set the address of module a to 0xFFFF and the channel to 0x04.
When module a is used as the receiver, it can receive all the data under channel 0x04 to achieve
the purpose of monitoring.
