Graphical User Interface¶
Download the GUI here: 32bit, 64bit
Please note that the 64bit version is no longer usable with the latest JRE version!
The USBoard is provided together with the USBoard configuration GUI, a graphical parameter editor.
The USBoardGUI requires a PC with:
- RS-232 interface (COM port) and
- Java® Runtime Environment 1.5 or later.
The connection between serial interface and USBoard is established by a special cable which can be obtained from Neobotix or self-constructed using the specifications. This cable also connects the USBoard with an appropriate power supply. A working supply is indicated by a green LED on the board.
To start the application, simply double-click on the
Make sure to use the program version that matches your operating system.
The GUI can also be used on machines with Linux or Mac OS.
This requires that the Java runtime environment can find the correct RXTX library.
It is also necessary that the user has the permissions needed to access the serial interface.
When using Ubuntu Linux please install the package
librxtx-java and add the user to group
Establishing a connection¶
Before starting a connection via the USBoardGUI, please make sure that the USBoard is connected
- to the PC’s RS-232 interface and
- to a power supply (LED lights up).
Now select the correct communication port in the application and
Connect button, to create the connection.
After establishing a connection, first data will show up. Depending on currently set parameters, measured data are updated automatically in defined interval or can be read manually by clicking the Request buttons. If the measured distance of a sensor falls below its specified warning distance, the value is displayed yellow. In case of under-running the alarm distance, the colour changes to red. As long as any measured distance is below the according warning or alarm distance, the according LED on the USBoard will light up and the relay is activated.
The measured values of the analogue inputs (voltage range 0V – 5V) are displayed as percentages below the distances.
Closing the Connection¶
To close the connection to the USBoard, just click the button
Configuring the USBoard¶
In USBoardGUI’s left column several parameters regarding the communication settings of the USBoard can be defined.
The CAN base ID and transfer rate for communication via the CAN bus can be set in the
The general transmission behaviour can be set in the
Transmission Mode panel.
The following table explains the different transmission modes. The interval parameter is only relevant for continuous transmission.
|Request||Send only on request|
|CAN cont.||Send continuously via CAN bus|
|RS232 cont.||Send continuously via RS-232 interface|
|RS232 + CAN cont.||Send continuously via both interfaces|
Configuring the Sensors¶
Various parameters of the ultrasonic measurement can be set in the right part of the GUI. Each sensor can be activated separately by marking the check-box beside its name. Deactivated sensors send neither ultrasonic impulses nor data. The warning and alarm distance of each sensor can be set in the edit fields to the right of the measurement indicator. The ID and analogue inputs of the USBoard are not configurable.
The USBoard is – despite warning and alarm functions – no safety system and can only provide supporting, non-safe information. Never use the USBoard for safeguarding of dangerous areas or movements.
Transferring the Configuration¶
Changed configuration parameters have to be transmitted to the USBoard to come into operation. The USBoardGUI offers buttons for two available options:
Write to Boardtransfers the parameters to the volatile memory of the USBoard. After the next restart, the old parameters from the non-volatile memory will be used again.
Write to EEPROMwrites the parameters into the non-volatile memory of the USBoard, so these parameters will be used until they are overwritten by using the same command.
To load the current parameter set from the USBoard and display it in the USBoardGUI, click the
Read from Board button.
Please note that all previous changes in the input mask will be lost.
Saving and Loading Configurations¶
Save to File and
Load from File permit the user to save
the current configuration into a file on the local computer or load it from one.
Simply enter the file name or select an existing file in the dialogue that
appears after clicking either button and confirm by clicking
The USBoardGUI writes log files for debugging purposes.
The information that is to be logged while the GUI is running can be chosen
from several different levels between
Severe (critical problems only) and
Finest (every action).
The log files are located in the folder log in the same directory that the GUI is in.
A real time display of the currently active log can be opened with the button
Show / Hide.
