Section 4 Theory of Operation
Maxiva ULX COFDM Series
4.4.3 TCU Control
The heart of the Maxiva control system is the TCU (transmitter control unit). Each
cabinet contains a TCU. The main cabinet (cabinet 1 in multi cabinet systems) contains
an enhanced TCU (with a GUI screen), while additional PA cabinets contain a basic
TCU (without GUI screen). The basic TCU will not be equipped with all of the same
components as the enhanced unit. The cabinet 1 TCU assumes the role of master
controller in multi cabinet systems. TCUs in added PA cabinets are slaves.
