Linx HumPRC Series Data Manual page 39

The Reload Key command copies the key in non-volatile memory (NKN)
to the volatile location (NKV). This allows a sophisticated system to change
the keys during operation and quickly revert back to the default key.
The Non-volatile Reset command (FF 07 FE 47 20 FE 2A FE 3B) sets
all non-volatile registers to their default values. When the configuration is
reset, the following message, shown in quotes, is sent out the UART at the
current baud rate, then the module is reset, similar to a power cycle:
"\r\nConfiguration Reset\r\n".
This reset can also be done by toggling the PB line as described in the
Restore Factory Defaults section.
