The communication ports available on the computer can be seen in the Device Manager of
Windows. The USB driver automatically creates a virtual COM port when the
communication module is connected and will appear in the Device Manager under the
section “Ports” - “Silicon Labs CP210x”.
If the communication is established, all the information is downloaded from the RTD
Transmitter and the right section of the main windows (“Device Information”) is updated
with the actual values. If the communication cannot be established an error message will
appear. If the communication port cannot be found the message will display
“Communication Port Not Available”. This means the communication port selected is not
configured on the computer or used by another peripheral. If the communication port is
valid but the communication cannot be established with the RTD Transmitter, the message
will display “Device not found”. In this case make sure the RTD Transmitter is connected to
the communication port selected and the wiring was made correctly. Once the
communication with the RTD Transmitter is established, the “Program” button will become
enabled. Clicking on this button will give access to the programming window.
