Mounting in the aircraft
Since Altis v4 uses atmospheric pressure for its measurement, it has to have open access to the outside
atmosphere. It must not be completely sealed inside the fuselage or other box. As most standard R/C
aircraft are not fully sealed, it is usually not necessary to do any special modifications for installation. The
Altis v4 can simply be put in a free space inside the fuselage.
If the unit is mounted outside the aircraft, the location must be carefully considered. The unit must be
mounted away from the airflow caused by the propeller.
Avoid mounting your Altis v4 on parts of the plane that might become hot during operation.
Connection for data logging only
If the Altis v4 device is used purely as a logging device, connect the device to any free receiver channel as
shown in Fig 2. The signal polarity must be observed as shown in Table 1.
Competition connection with internal BEC
For competition use (like F5J FAI, ALES, etc.) the JR input cable has to be connected to the R/C receiver,
and the JR ESC cable has to be connected to the output connector on the main measuring unit board.
See Fig 3. The signal polarity must be observed as shown in Table 1.
