Channels
Figure 61:
An example of channel Z editing. Z is typically used for the engine
RPM.
Sensor
A list of sensors available for the selected channel and selected func-
tion is provided. Select one from the list. This tells Daqu what kind of
signal is to be expected on this channel.
Report time
defines how frequently Daqu sends measurements to the CAN
bus. This is defined as a time interval between two measurements being
sent. Small value means that measurements are send frequently.
Filter
defines a low level filtering. This is a low pass filter time constant.
A larger value means that more time is needed for a measurement to
react on a sensor change. The optimal value depends on the sensor and
function type.
Pulses
value is specific for digital channels (Z,Y). It defines how many digital
pulses are required for one event. For example, some rotor sensor may
issue 12 pulses per one rotor revolution.
Prop reduction
is specific to Engine RPM function.
Some engines have
reduction gear boxes (Rotax for example). If the reduction ratio is
entered, then the propeller RPM will be shown instead of the engine
RPM. This value is typically set to 1.0, which results in engine RPM.
Figure 62 shows another example. In this case an oil pressure sensor is con-
nected to channel D1. As a generic family of sensors is selected in the
Sensor
item, an additional items appears at the bottom –
Max value (at 20 mA).
.
This value is used to define the sensor range. In the example the value is set
to 10 bar, which is typically used with Rotax engines.
