SYMPTOM CHECK
System “not working” Strapping and SDI – HPA Status
No communication with
avionics
Check multi-control wiring
Unable to place an HSD
Swift64 call
Activate Report 38 and check for power request
value.
Check RF connections between the Transmit cable
and the HSD DLNA
Check the connection of the receive cable between
the HSD and the splitter
Unable to place an Aero
H/H+ call
Check transmit cable between the Aero H RFU and
the HSD HPA
If a low receive value is indicated on either the HSD
or Honeywell SDU, check splitter connections
(receive cable from DLNA to the splitter)
Check the connection on the Aero H RFU receive
cable connector
Calls dropping when
placing multiple calls
HPA to antenna, cable loss value may not be
accurate.
Re-measure the HPA to antenna cable loss and
re-configure the HSD system to match the revised
value.
