PM5563 firmware downgrade from 4.3.2

[DCarlson]

If a meter is at firmware 4.3.2 or 4.3.4 can it be downgraded to 4.2.5 or 4.2.1 seeing as there is a cyber security fix at 4.3.2?

Thanks

Hi @DCarlson 

As mentioned in user guide and release note, when meter(PM5560/PM5563) upgraded to version V4.x.x from V2.x.x, you cannot downgrade to V2.x.x. but downgrading V4.x to V4.y is possible however the features, fixes and improvements that have been made on recent firmware versions will be removed which is not recommended.

Thank you.
