Adding Any Power Supply to the Module Bus
•
An additional power supply’s positive is not connected to the main control module bus positive with an isolating
diode, as was previously done.
•
The modules using power from the additional power supply have their module bus Data A and B interconnected as
normal.
•
The additional power supply’s negative is connected common to the module bus negative.
•
The additional power supply’s positive is never connected to the module bus positive.
