8 AVIONICS AND AIRFRAME
8.6 Other avionics devices
Support for the Honeywell Digital Compass HMR3000 is under development.
8.7 Slave mode
A device type in the configuration settings, “NMEA Out” is defined for use in joining two Altair
systems in a master-slave mode.
In the master, the second COM device can be set to NMEA Out, and all data received in the first
com device (as well as outgoing data) will be sent to the slave.
In the slave, the first COM device can then be set to “Vega” or “Altair Pro” and this system receives
all data as if it came from the Master’s GPS and connected instruments (Vega, FLARM etc).
8.8 Interface to external loggers
XCSoar has support for declaration and handling special sentences used by commercial flight
loggers. Devices that are supported but do not include declaration support include Posigraph and
Colibri.
