antenna cable connector into Core. PowerFLARM will not work
without good GPS reception.
The GPS antenna should be located in a horizontal position such
that it has an unhindered sky-view, including when the aircraft is in
a turn. There should be no electrically conducting surfaces (e.g.
metal, carbon fibre) over or immediately alongside the antenna.
Ideally, the antenna will sit atop the instrument panel coaming.
Conducting surfaces under the antenna may have a positive effect
upon antenna function.
If more than one GPS antenna is present in the aircraft, it is recom-
mended that they are at least 1ft apart; the same holds for separa-
tion from all other Core antennas.
USB
Core has a built-in USB A 2.0 connector for a memory stick. The
stick is used for device updates and readout of device information
and flight records. See the section ‘Device update’, ‘Flight recorder’
and ‘Feature licences’ for details. Maximum size is limited by FAT
system (32GB).
The USB stick must not be connected during flight
except for
special purposes as advised by FLARM Technology or its agents.
USB stick transactions take place:
•
Whenever PowerFLARM is switched ON with a USB stick con-
nected.
•
When triggered by a display or flight computer (currently im-
plemented: Readout of flight records).
Transactions after switching PowerFLARM ON are executed in the
following sequence:
•
Apply device configuration (FLARMCFG.TXT)
•
Write device information (FLARMDEV.CSV)
•
Updates: Firmware, obstacle database, licences. (PowerFLARM
restarts if any update is done (Status LED OFF for three sec-
onds); this is to allow expedited updates of multiple devices.)
