The LX9000/8000/8080 digital unit is connected to 12 Volt power via the 15-pin SUB-D
connector. The LX9000/8000/8080 digital unit and the V5 unit (57 mm units) are connected
via the RS485 bus (9 pin DB connectors).
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 LX9000/8000/8080 digital unit.
