Reply Switch

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

Reserved

Data

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

4 bytes

2 bytes

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 figure, central control hosts translate network commands through serial ports to control any network device.
