"All units in one system must be the same type and firmware version, this includes same size, system voltage, and feature set. The type is indicated by the first four digits of the firmware version number."
Regarding this statement, how often do the first four digits change ?
Assuming the first four digits are related to manufacturing date.. Depending on supply and demand for that product it could be 6 months or 12 months before a different "hard" firmware of the one product is distributed.
I only ask because I am designing a system for a customer who would like to start small and upgrade later. But if he can't parallel the same product because the first four digits don't match then we're in trouble. But if he upgrades with in 6 months it should be okay?
