Serial Port

Choose the serial port that is connected to your PX3. Click the down arrow to show the list of available serial ports and then select the serial port you have connected to your PX3. See Finding the appropriate serial port for a USB to Serial Adapter if you're using a USB to Serial Adapter and are not sure which port to choose.

Refresh Port List

Click to update the list of available serial ports, which may be helpful if you plug in a USB to Serial Adapter after the program has started.

Test Communications

Reopens the serial port and verifies that the PX3 Utility can communicate with your PX3 and determine its RS-232 speed.

If you change the RS-232 speed using the PX3 front panel use this button to allow the PX3 Utility to discover the new speed.

If the PX3 is turned on and has an illumnated front-panel LCD screen, it should respond to Test Communications with an "Information" dialog indicating that your PX3 is running the "Main" program.

If your PX3 is in its "Boot Loader" state, it should respond to Test Communications with a "Warning" dialog indicating that the PX3 is in its boot loader.
