Troubleshooting

It is important when selecting the com port for updates and RS232
communication to be aware of what com port is being used on the PC for the
upgrade, whether it be a built in serial port on the PC, or a USB to serial adapter.
Selecting the incorrect com port in an update program or an RS232 terminal will
result in communication errors.
Additionally, if using a USB-to-Serial adapter, please verify that the drivers are the
latest available drivers for the device. Often there are newer drivers available on
the manufacturer's website than the supplied CD-ROM. Old or incorrect drivers
may allow the adapter to display in Windows but can sometimes cause connection
issues.
If you do encounter an error, please refer below for the various error messages and
potential solutions.
