Chapter 4: Operation of control software - Cerasonar
Cerasonar provides user with a fast interaction to control one or more devices
through multiple methods: TCP/IP, USB, common serial port (RS232/485). Easily
set DSP functions of device, GPIO control and inquire central control codes.The
configuration parameter can be stored in presets, convenient for various
applications.
4.1 Operating condition
Cerasonar is suitable for Win7/8/10/11 x86/x64 PC system with Microsoft .NET
Framework 4.0. When connecting device in USB method, the device will

automatically ejects the storage disk, user can unzip software in Windows, no
need to setup.
Double click Cerasonar.exe, the main interface will pop up.
4.2 Connections setting
If connect device by using
network cable, click Setting in
Device List, choose TCP in
Connection windows.

- 7 -
If connect device by using USB
A-B, click Setting in Device List,
choose USB in Connection
windows.
If connect device by using
network cable, click Setting in
Device List, choose COM in
Connection windows. Please
check port and baud rate
carefully for 232 or 485 before
setting.
The software will scan device the method set
in last time, to check if device is connected. If
successfully connected, devices will be shown
in device list.
User can mute device, refresh connecting, or delete device in this window. Single
click device, to load function interface.

- 8 -
When using TCP control, there is a
situation that only one point is
displayed after scanning, but can not
connect device. In this case, user need
to change the IP address of the device
to the same network segment as the
PC computer.
Right-click the device enclosure, a Net
Setting window will show.
Set IP address of device refer to IP
showed in the bottom of the software.
