When delivered, all modules are in "00" master module status by default. When multiple modules
are connected in parallel, only one module remains in master module status, and other modules are set
to submodule status. When a module is used independently, the default settings can be used.
On the basic module set to the master module, the module address on the main board is displayed
as "01".
