<INSTRUMENT FUNCTION> CONNECTION LOST
: This indicates that the network is still functioning, but a
device in charge of providing a specific role on the network has stopped communicating. This means that other screens
in the system can no longer display information related to that function. If you receive an “EMS LOST” message on an
EFIS product, all EFIS-related pages still function, but all EMS pages are blank. This failure can warn about subsystem
failures, such as an EDC or an OAT. In these cases, the device falls back to a local OAT or EDC, if it is available. The
<INSTRUMENT FUNCTION> LOST message is preceded by “THIS:” or “DSAB:” on each connected display
instrument. If the label is “THIS:” then the screen with this label is the source of the failure. If the message begins with
“DSAB:” than the message indicates a failure on another device.
This message relates to the function on the network that goes missing, not the specific name of the unit that fails. A
FlightDEK-D180 can be a provider of EFIS and/or EMS data, so the failure of a D180 would present as "EMS" and/or
"EFIS" lost, depending on its function in the network.
If the HS34 is not communicating on DSAB properly, both the NAV and GPS lights are illuminated. During
normal system operation both lights will never be illuminated simultaneously; dual illumination indicates a
communication failure. Additionally, if the DSAB network fails in flight “DSAB ERROR” will be annunciated
via HS34’s the audio output.
