3. Use BU-Config to select the serial port on your PC where the cable is plugged in.

Setting the Serial Port
BU-Config transfers configuration information between your PC and the BU-905U-L using serial ports.

to the module you are programming.
To set the serial port:
1. Open the project.
2. Select Utilities » Serial Port Setup.
3. Select the serial port you want to use for configuring the unit (e.g., Com 1):
4. BU-Config marks the serial port with a tick and uses the serial port the next time you transfer configuration information between your PC and a
module. The selected serial port is also displayed in the Comm Port field at the bottom left of the BU-Config window.
5. You can now transfer configuration information between your PC and the module. For more information, see the next section.
