Manifold Pressure (MAP)
Connect a flexible plastic tube with an inside diameter of 4mm (0,16 inches) to the EngiBOX MAP
port and to the Engines manifold pressure connecting nipple. Make sure the tube fit tightly.
Note: see your Rotax manual for the manifold pressure connecting nipple position or contact your
Rotax Service Center for assistance.
Oil Pressure
The EngiBOX connection board is pre-configured to be used with the Keller type 4-20 mA pressure
sender for Oil pressure. The POIL sensor selector switch is set to "2" (ON).
Instead, if the resistive 10 Bar/150 psi VDO type pressure sender is connected it is neccessary to set
the POIL sensor selector switch to "1". See Figure 6.

Note: See the compatible sensor table for each parameter at page 8.
Note: PTO stands for power take off side and MAG for magneto side of the engine.
Power supply
Power the EngiBOX from an 10 to 35 Vdc supply. Mount on the power wire (RED) the 1A fuse holder,
provided in the box, to protect against short circuits.
Note: Use the Aeronautical grade wires for power supply that are supplied together with the
EngiBOX (black -- / red ++). For connection see the connection board (see Fig. 5).
