4.2. Connection Tab
At start, the GUI will open the Connection tab and the window will look like in Figure 3.
On the left side of the window, there is the connection to the network section. This
contains 3 fields and 2 buttons, as follows:
●Port - this entry field allows the user to select the physical port to which the RS485
to USB adapter is connected. Information on how to obtain the port number can be
seen if the mouse cursor is hovered over the field for about 1 second.
●Baudrate - this scroll down menu allows selecting the baudrate of the connection.
This selection needs to match the baudrate of the IND-Thermal-90 sensor. By
default, this value is 19200.
●Parity - this scroll down menu selects the parity of the connection. This selection
needs to match the parity of the IND-Thermal-90 sensor. By default, this value is
Even.
●Connect - once the settings are correctly selected, pressing the button Connect will
open the communication port to the RS485 network.
●Disconnect - disconnects the port.
The slave device selection is placed to the right of the network connection, separated by a
vertical line. Once the network connection is established, select the slave device to address.
The slave IDs can be in the range of 1-247, default value being 1. Once the correct slave ID
is selected, press Select slave. This will start a routine that will verify the connection to that
specific device and, if the connection is validated, it will enable the rest of the buttons of
the interface.
Finally, on the far right side of the window, contained within a box, there is a section which
can update the selected device network configuration. This can be done by selecting the
new desired parameters, such as baudrate, parity, and slave address, then clicking on
Update. A small pop up window with more details and a confirmation button will appear.
The change of these parameters corresponds to the holding registers at address 0 (Device
address) and 1 (RS485 parameters).
A sensor restart (power off-on cycle) is highly recommended after this action.
