miniDaqu — Manual
3. Wiring in General
some other instrument (e.g. propeller pitch controller). The pins are not
connected to the CAN cable. Two separate wires must soldered directly to
the pins and routed to the instrument.

ECU Connector
This connector is used to connect Daqu and engine ECU. Normally, not all
pins are used. Some ECUs are connected via CAN bus and some are connected
as a RS-232 device. On the Daqu cable side, a female D-SUB 9 connector
is needed. On the other side of the cable are free ends. The pinout of the
connector is given in table 3.
This connector also host two pins, which can drive an external relay. This
can be used for automatic start switch or to trigger some external alarm.

Wiring in General
This section reveals some basic principles of correct wiring. Not all options
are described, just typical and most common ones. The following schematics
shall be considered as general wiring help. There are also other sensors that
Daqu can make use of and are not described here.
When you encounter a problem, contact Kanardia and we will try to provide
you with a solution.
See your sensor manual and specifications before wiring and installing sensor.
Follow the sensor instructions. Make sure that the wires are secured and they
will not get loose due to vibrations.
