(low voltage). Refer to the Flightcell website at
wiring diagrams.
Two ground return pins are provided for the five primary General-Purpose Inputs
(GPIs) (pin 10 and pin 11 of the primary connector); these are internally connected to
power ground and aircraft chassis ground, so the aircraft chassis can be used as
a ground return for these GPIs if required.
Configuring the inputs
These inputs can be set up using the DZMx Plus Control Head menus or using
DZMx Connect. In practice, it is easier to set them up using the DZMx Plus Control
Head menus as the DZMx Plus reports the status of the input in real time.
Inputs 1 to 5 can be used either as two-state or as variable inputs.
Events can only be triggered on inputs 6-12 (on the input expansion card) by
pulling them to ground, as they are two-state inputs.
To set up the inputs using the:
1.
DZMx Connect app. Go to Settings > Inputs or MENU > Hardware Config >
Input Configuration.
»
Select the function that you want to assign to an input (e.g. Take-off
Switch).
»
Select Input Designation, then select the input which has been wired for
that function or select Not Installed.
2.
Using the DZMx Plus Control Head keypad. Select MENU > Hardware Config
> Input Configuration.
»
Select the function that you want to assign to an input (e.g. Take-off
Switch)
»
Select Input Designation, then select the input which has been wired for
that function or select Not Installed.
If using the DZMx Plus Control Head a pop-up will show the current state the DZMx
Plus reads from this input (e.g. Up/Down, On/Off).
If the state is wrong (e.g. DZMx Plus reports
“Collective is
Up”
when it is down, go to
Input Configuration and change the selected condition.
DZMx Plus Outputs
The DZMx Plus has two outputs, these are switches that can be used to turn an electrical
signal on or off. A typical use of an output is to energise a ring alert light on the aircraft panel.
Each output has two terminals, A and B. The output consists of an isolated switch, internal to
the DZMx Plus. When the output is active, the switch is closed (terminals A and B are
connected). When output is inactive, the switch is open (terminals A and B are
disconnected). The outputs can be configured to flash or simply turn on/off.
The events that can be configured to trigger the outputs on the DZMx Plus are:
Note
: Some specialised input functions will only appear in the
Input Configuration menu if the application (e.g. airline, firefighting, or PTT)
is enabled.
