EMSIS – User’s and Installation Manual
Figure 24: EMSIS Service menu.
There are many options displayed here. Some of them depend on the hardware, which is present on the
CAN bus:
Layout: Allows you to change the configuration layout. Normally, you do not need to change this.
AHRS level configuration – used to define the “zero” for the AHRS,
Compass calibration – used to calibrate the MAGU (magnetic compass),
Compass offset – used to make fine adjustment of MAGU,
Firmware update – used to update the software in Daqu, Airu, Magu,
RamBoot update – used to update the initial boot software,
Logger settings – used to define some logger settings,
Up/down – used to define default behaviour of up/down buttons
Set alt & IAS offset – used to adjust the zero for the altitude and airspeed sensors,
Set MAP & FF offset – used to adjust the manifold pressure and to set a fuel flow factor.
6.9.1 Layout
In most cases the correct layout is set in the factory and you do not need to change it unless we advise you
to do so. Figure 25 shows a window for selecting a layout.
Figure 25: Window for setting EMSIS layout.
When dialogue is opened:
use
up
and
down
button to change layout and confirm with the check button,
push the
cross
button to save and exit the window. EMSIS will restart.
6.9.2 AHRS Level
During the assembly of the AHRS unit into the EMSIS unit and during the installation of the EMSIS unit
into the instrument panel, a small misalignment may appear. This means that internal axes of the AHRS
unit are not parallel to the airplane axes – the AHRS unit is slightly rotated. Such misalignment can be
perfectly adjusted without loss of precision using the procedure described next.
