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 2bytes 1byte 1byte 128bytes
UDP: IP Address Port Data Length Reserved Data
After receiving the protocol format data packet, RS232 sends data in the protocol to 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 4 bytes 2 bytes 1 byte 1 byte 128 bytes
0x3a504455（’:PDU’）
0x1610A8C0 0xC350 0x09 0x00 ”HELLO DSP”
Application scenario: The function can be applied in scenarios when many central control hosts have no network
port. As shown in the below figure, central control hosts translate network commands through serial ports to
control any network device.
