Electrical Installation

The SV-INTERCOM-2S has one D25M connector for connection to SkyView and other devices.
Installers will need to fabricate a D25F wire harness. 20 AWG wire is recommended for power
and ground wires; 22 AWG wire is recommended for all other connections. Shielded wire is
required for audio connections (see Section
See Table 1 for harness pin/wire connections; see
specific wiring diagrams.

This mono audio signal mutes when audio
signals are received on other non-muting
inputs and radio inputs. Use this input for non-
critical mono audio signals.
Used for SkyView Dimming Output.
NOTE: If more than one SkyView display,
connect this to only one of the SkyView
displays.
This is the right channel of the stereo non-
muting input, typically used to receive audio
from SkyView or other EFIS systems with
stereo output.
Connects to COM radio #2 Headphones
Output.
This audio signal does not mute. Typically
used for a second COM, a NAV radio, or other
mono avionics alerts.
