3.2.7. Connection to the mains relay board
The control-board is connected to the CPU by a parallel data-line. It transfers the control
signal for the gas system. The CPU gets the information "tube obstructed“ and "gas
shortage“ via this connection. The gas values are delivered by the gas control board.
