The label is related to hardware revision. The firmware revision is only available in the configuration memory using the ‘0’ command. Since the configuration memory is corrupted it’s not possible to read out the firwmave revision, and you simply just need to test the ‘@RC’ command. If you send the ‘@RC’ command you will receive one ‘>’ if the feature is included. If you receives 3 ‘>’ you know that this feature is not included, and you need to reset the memory by using the ‘M’ command.
