troller Model

it can be upgraded into a dual-controller configuration by adding another controller
module and firmware upgrade (see software manual). If the model name is
designated with a “G”, it is not upgradable to a dual controller configuration.

S12S-J2000G or S12F-G1842 : NOT upgradable to dual-controller model
