1.3.3 PWR Board (06P0242)
Figure 1.6 shows the block diagram of PWR board.
The power on/off switch in the control unit generates PSW-H and PSW-L signals to send them
to PWR board via the display unit. The PWR board generates 5V, -5V, 12V 12VD, and +B
voltage (VTX).
The 12VD voltage (12VA) is supplied to the display unit via CPU board. The VTX voltage is
determined with TXV voltage from CPU board.
