Frequently Asked Questions (FAQ)
RX, TX and GPS-LED are flashing constantly
The data communication to mainframe is interrupted – the display is not receiving data for more than
3 seconds (data communication normally occurs every second).
-> Check wiring and plugs to mainframe.
-> In case of newly-installed display, check adjustment/configuration of the transmission rate of the
interface; the mainframe possibly sends correctly – but too rapidly (see also tips in chapter
“Configuration”)
The “adjusted” volume level is not saved as setting; after start-up the buzzer is always set on “loud”.
-> This function operates intentionally for safety reasons; at the beginning of each flight day FLARM
TM
must
be adequately audible. The buzzer can be intentionally adjusted afterwards to a lower volume level or
even disabled completely.
After a change-over from older V2 display to the new V3+M display, the display is not illuminated
The first display generation – the V2 –operates with a 3.3V supply from FLARM
TM
; a connecting cable
a 4-pole cable is used.
The new displays (V3+M) need the power supply provided from FLARM
TM
mainframe requiring
a 6-pole connecting cable.
Both systems need the same 6-pole plug – by older displays both outer pins are not connected!
-> By a system change-over from V2 to V3+M displays a new 6-pole connecting cable is required.
