Dynon SkyView HDX - Electrical Installation

SV-COM-X83 Transceiver and Panel Installation and Configuration
SkyView HDX System Installation Manual - Revision E 15-5
15.2 Electrical Installation
Use this section in conjunction with the information contained in Section 25 Appendix C:
Wiring and Electrical Connections.
15.2.1 Power Input
SV-COM-X83 is compatible with 12-volt and 24-volt systems (10 to 30 volts DC). Power
input is connected to the transceiver and the SV-COM-PANEL. See wiring diagrams and
pinouts for details. Note that the transceiver has two pins for POWER input (Pins 24 and
25) and two pins for GROUND (Pins 19 and 22). Use both Pins 24 and 25 for POWER
input to the transceiver and use both Pins 19 and 22 for GROUND to the transceiver.
15.2.2 Audio Signal Grounding
Ensure that audio input and output grounds terminate at a single point—typically the
intercom or audio panel. Do not connect an audio input or output ground to aircraft frame
ground or a power or data ground. You should run dedicated wires from audio devices to
the single point audio input and output ground.
15.2.3 Audio Shielding
Shielded cable must be used for all audio connections. The shield should be connected
to ground only at the single point audio ground.
15.2.4 SkyView Network Connectors
The two (2) D9 connectors on the back of a SV-COM-PANEL display are SkyView
network connectors. They have identical pinouts and are electrically connected inside the
SV-COM-PANEL (i.e., they are completely interchangeable). Installers may use either
connector or both connectors in SkyView installations. Using both of these connectors
allows installers to daisy-chain another SkyView Network module (such as the SV-EMS-
22X) that may be co-located behind the panel. Reference
Table 67 on Page 25-10 for SkyView Network Connector pinout information.
Note that these connectors are not serial port connectors.
15.2.5 Electrical Connections
15.2.5.1 Harness Construction
Because the SV-COM-X83 (SV-COM-PANEL connected to the transceiver) can be
mounted in a variety of locations, the harness length requirements will vary from
airplane to airplane. Thus, Dynon Avionics does not supply pre-manufactured
harnesses for the SV-COM-X83. Instead, your SV-COM-X83 includes connectors and
pins to generate a wide variety of harness configurations. Refer to the sections below
for detailed wiring information.
Additional harness construction and wiring information can be found in Section 25
Appendix C: Wiring and Electrical Connections.
