Byte5 controlling type is 4.
The data length of byte6 is 1.
When byte9 is 1, it means turning on central control replies switch; and 0 means turning off replies.

4.3 Serial Port-to-UDP (RS232 To UDP)

DSP devices support RS232 translating into UDP. The protocol formats are as follows.
4bytes prefix 4bytes
UDP: IP Address
After receiving the protocol format data packet, RS232 send data in the protocol to the appointed IP addresses and devices at
ports.
For example, when sending data "HELLO DSP to device port 50000 of device "192.168.10.22", the protocol commands are as
follows.
4 bytes prefix
0x3a504455（':PDU'）
Application scenario: The function can be applied in scenarios when many central control hosts have no network port. As shown
in the figure, central control hosts translate network commands through serial ports to control any network device.
