Optional CAN Bus Components or Accessories

Components listed below are all optional. This means they are not required
for normal Nesis operation.
2.1 Components in the Nesis System
Engine monitoring (called DAQU) is required to
read the engine, fuel and aircraft related sensors
and to put the obtained information on the CAN
bus. It has three digital channels (Z1, Y1 and Y2),
twenty analog channels (A, B, C, D) and a spe-
cial manifold pressure connector (A13). DAQU also
hosts +5/+12 V power output and ground (GND).
Digital channels are typically used to read engine
or rotor RPM and fuel flow sensors. Analog chan-
nels are typically used to measure CHTs, EGTs,
coolant temperature, oil temperature, carburetor
temperature, airbox/gearbox temperature, fuel lev-
els, system voltage, electrical current, oil pressure,
fuel pressure, hydraulics pressure, pitch trim, flap
position and many others.
DAQU comes in three forms:
• Standard Daqu is typically used with carbu-
retted engines like Rotax 912 UL, ULS, Rotax
914, Jabiru, Lycoming, Continental, etc.
• Mini DAQU is typically used with an engine
that has its own ECU. Rotax iS, D-motor,
Geiger Wankel, MW, etc.
• In some cases there is not enough channels
on mini DAQU. In this case, standard DAQU
modified for ECU engine can be also used.
