LXNAV Magnetic Compass
The LX magnetic compass is comprised of a 32–bit micro–controller combined with 9 sensors (3 axis, accelerometers, magnetometers), to generate a very accurate measurement of the magnetic heading (compared to a GPS calculation). The magnetic heading is tilt compensated; calculations are performed 50 times per second and produce a stable reference heading for wind calculations and course change of direction information. The compass automatically calibrates itself during flight. The LX magnetic compass can be added to any existing or new LX90xx or LX80xx unit through a standard RS–485 bus connection. The compass will work only with V9, V8 or V80 variometers.
Compass module must be connected to RS485 bus through RS485 splitter. It must be installed to the place where is no strong magnetic fields (Irons or ferromagnetic materials), cables with AC current or not constant DC currents.
When installing magnetic compass use screws made of non-ferromagnetic materials (plastic or brass).
When installing a magnetic compass, the main device should be switched off, otherwise it will not be detected.
• The location should be magnetically benign.
• As far as possible of metal parts, power cables.
• In case of small magnetic interferences is available user calibration.
• Very important is orientation of the magnetic compass (compass has marked TOP position.
When a compass is connected to the system use this menu to preform calibration of compass. Before calibration, please make sure that compass is installed properly. Refer to compass and installation manual for more info about installation.
It is very important that compass is installed away from power cables, other compasses, speakers and all other magnetic components in the aircraft. Keep maximum possible distance to such components (at least 30cm).
