Computer Management" " - " Device Manager " -
" Ports (COM and LPT) " and using the right mouse button select the not correctly installed COM port ( "UA 400
COM Port" or "WR 300 COM Port" ). Then click on " Update Driver " and follow the instructions in the dialogue
that opens; then the driver should be correctly installed.
Windows 7 / Windows 8 / Windows 10 : Open "Control Panel", under "Device Manager" there, select "Ports
(COM & LPT) ". Then proceed as described above.
Special features under Windows 7/10: When executing the program, the request “Do you want to allow the
following program from an unknown publisher to make changes to this computer?” must be confirmed with
YES . If this request should be permanently suppressed, the following procedure is recommended:
In the directory " C:\Program Files\firmupl" , click on the file “firmupl.exe ” with the right mouse button. Select the
entry " Allow " under " Properties " in the drop-down context menu. The request should no longer be displayed
