SkyView Pin 26 – White wire
24V electrical systems require a 1.1KΩ resistor (included in
the kit) in series with the SV-BUTTON-LEVEL’s white wire
and the SkyView display’s Pin 26 white wire.
If you have multiple SkyView displays, connect this wire to
only one display.
SkyView Pin 28 – Orange / Black Connect wire. If you have
multiple SkyView displays, see the note below –
Considerations for SV-BUTTON-LEVEL…
Prior revisions of the SkyView System Installation Guide recommended that in
SkyView systems with multiple displays, for redundancy the External LEVEL
Button should be connected to all SkyView displays in parallel. The following
recommendations supersede that earlier guidance.
Do not connect the Orange / Black wire of the SV-BUTTON-LEVEL directly to the Orange / Black
Wire (Pin 28) of multiple SkyView displays. If you do so, when one display is powered off, it will
cause displays that are powered on to see the LEVEL input as being pushed (the display
powered off will “ground” this input). This could cause the unintentional activation of LEVEL
mode or could prevent the SV-BUTTON-LEVEL from operating.
Installation Options for SV-BUTTON-LEVEL on Multiple SkyView Displays
Choose one of these options if you have multiple SkyView displays and you want to connect SV-
BUTTON-LEVEL to all displays for failover / redundancy:
Connect the SV-BUTTON-LEVEL to only one display. The SV-BUTTON-LEVEL will operate
for all displays in the SkyView system as long as the display the SV-BUTTON-LEVEL is
wired to is powered on and operating normally. As a non-flight-critical function, the loss
of the SV-BUTTON-LEVEL in some display failures may be acceptable for your
installation.
o In SkyView, use of the LEVEL function via the soft keys via any operating SkyView
display is still possible, as well as pushing the LEVEL button on the (optional) SV-
AP-PANEL.
Install a diode for each individual display’s connection to the SV-BUTTON-LEVEL (not
included in the SV-BUTTON-LEVEL kit). The diode should be installed with the cathode
end (painted band on the diode) oriented towards the SV-BUTTON-LEVEL, and should be
installed in-line with the contact wire between the SkyView display and the SV-BUTTON-
LEVEL. One diode is needed per button, per display. Any diode will work for this
