Select the “Connections” tab
to define how APIC connects to the various measurement devices. APIC can connect to multiple devices either
through a serial (RS232) connection or an Ethernet network. This page allows the user to define how a
device is connected to APIC and to reset the connection with a device if there
is a failure.
APIC will automatically scan
for a CF Card GPS during start-up if no connection has been previously
defined. If a CF Card GPS is found, APIC
will set the connection to the communications port found and set the speed to
4800 baud. APIC can run with any serial
GPS that outputs standard NMEA sentences.
If an Attitude Heading
Reference System (AHRS) is installed, APIC will use it as the primary source of
heading, pitch and roll data. Otherwise
it will use GPS data to determine attitude.
The Honeywell devices
(HMR3000 & HMR3300) are low cost tilt compensated digital compasses and do
not output valid roll data during dynamic flight conditions. As a result APIC will only use the heading
and pitch data from these devices. Roll
is computed from GPS data.
Up to 2 Engine Pods (Epod)
can be installed. One per engine.
Currently the Environmental
or (Vpod) is not selectable.
