Daqu — Manual 3. Wiring in General
Standard cable length supplied with Daqu is 1.5 m (4.9 feet). A different
length may be also provided without any additional costs, when such length
is specified at the time of the order.
3 Wiring in General
This section reveals some basic principles of correct wiring. Not all options
are described, just the most common ones. The schematics presented in this
section shall be considered as general wiring guideline rather than a recipe.
There are also other sensors that Daqu can make use of and are not described
here.
When a problem is encountered, contact Kanardia and we will try to provide
you with a solution.
Check sensor manual and specifications before wiring and installing the sensor.
Follow the sensor instructions. Make sure that the wires are secured and they
will not get loose due to vibrations.
3.1 Connection Wires
Tefzel (or similar grade insulation) is recommended for all wires. The signal
wires thickness shall be AWG 22 unless other thickness is recommended.
3.2 Daqu Ground Pin (GND)
NEVER connect any Daqu ground pin (GND) directly to the aircraft or engine
block or to common system ground. Routing ground through aircraft/engine
block will not damage Daqu, but will create unnecessary ground loops, which
in turn may cause incorrect readings from the engine sensors, especially resis-
tive ones.
Daqu ground pin should be used only when:
1. An active sensor is installed and GND pin is used together with some
+5/+12 V power pin to power the sensor and sensor signal is connected
to one of B, D, E or Y channels.
2. Isolated resistive (two wire) sensor is installed and GND pin is used as
a reference ground for the sensor. In this case sensor is connected to
some A or E channel.
