USB to Serial Converters

If you are using a serial to USB converter to connect through the logger programming port, there could be a problem with the USB device configuration. Sometimes, shutting down the SDR "Modify iPack Settings" window is enough to restart the USB to Serial device. If the USB to Serial converter is brand new, it may require the installation of drivers in order to operate. Further, you may need to investigate your hardware profile in the Windows Device Manager control panel and make sure the device is properly activated and is mapped to a COM port 1-4.

If all else fails, you can restart your computer.
