Ethernet port sound noise sensorInstructions:
Power supply: DC12V, 10M speed IP/UDP communication, supports ping.exe command response.
Port: The port and IP can be set by entering commands through the serial port. RS232 communication: communication mode 9600, n， 8,1, ASIC characters for information, enter key 'Enter' corresponds to hexadecimal 0x0d+0x0a.
--------------------------------------------------------------------------------------
Is the device's IP: CM+IP=? (Enter)
Example: The device answers CM+IP=192.168.0.1 (Enter)
------------------------------------------------------------
Set IP to 192.160.4.5, serial input CM+IP=192.160.4.5 (Enter)
Query the port of this device: CM+PORT=? (Enter)
Example: The device answers CM+PORT=8253 (Enter)
Reset port to 8255, enter the command CM+PORT=8255 (Enter)
----------------------------------------------------------------------------------------------
Other online devices within the local area network obtain the noise measurement value of this device:
Port, IP, and device match, transmitting CM+NS02=? (Enetr) command, the device sends back CM+NS02=xxx. x (Enetr) message, returning the current noise value xxx. x.
