1. Introduction miniDaqu — Manual
1 Introduction
First of all, we would like to thank you for purchasing our product. Mini Daqu
is data acquisition unit designed for monitoring engine parameters. Mini Daqu
reads various engine sensors, processes the readings and transmits them to the
CAN network, where other units can make use of these readings. In addtition,
mini Daqu connects to engine ECU and reads data from it. The data is then
transmitted on the Kanardia CAN network.
We strongly recommend you to carefully read this manual, before you start
connecting mini Daqu unit with your engine sensors. The manual provides
information about the installation of the mini Daqu unit and connecting it
with sensors, probes and transducers.
Daqu comes in two versions:
Standard, larger version is used for most engines: Rotax, Lycoming,
Continental, UL-Power, Simonini, Hirth, etc. Here, engine sensors are
directly connected to four twelve pin connectors. It also has one five pin
CAN connector and ϕ5 mm outer diameter intake manifold pressure
connector.
Mini version a.k.a. Mini Daqu is used for some modern engines equipped
with digital output from their ECU. Here, most engine sensors are con-
nected to ECU and mini Daqu simply reads sensor values from ECU
digital output. Besides information from ECU, mini Daqu allows con-
necting additional sensors like rotor RPM, fuel level, trim position, etc.
Mini Daqu is typically used for Rotax iS, D-motor and UL Power en-
gines. Mini Daqu has only one twelwe pin connector for sensors and
two D-SUB nine pin connectors – one for ECU and the other for CAN
network.
This manual is dedicated to mini Daqu, hereinafter referred to as Daqu.
1.1 General Description
Daqu is en electronics device, which is used to connect various engine sen-
sors, probes and transducers. It reads analogue or digital signals, converts
the signals into digital CAN messages and transmits the messages over CAN
network where other devices connected to the network access these messages.
In addition, it connects to engine ECU unit. The data received from the ECU
is converted and re-transmitted on the CAN network. This way it efficiently
