5.2 Connection and Functionality Check of All Peripheral Units

The main display unit is connected to 12 Volt power via the 15-pin SUB-D connector. The
main display unit, vario unit and other vario indicators are connected via the RS485 bus and
the connectors are labelled with "RS485" at each end.
Please ensure that both units are connected correctly before the first power on. The power
wires (red and blue) should be connected to the main display unit.
