Version 16.10 AF-6600 AF-5000 Series Install Manual 68
Electrical Installation
Power Input
AF-COM-C25 is compatible with 12 volt and 24 volt systems (10 to 30 volts DC). Power input is
connected to the AF-COM-425, which then supplies power to the AF-COM-PANEL via the 5-wire cable
between the two units. See wiring diagrams and pinouts for details.
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.
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.
Advanced-SV Network Connectors
The two D9 connectors on the back of a SV-COM-PANEL display are Advanced-SV network
connectors. They have identical pin-outs and are electrically connected inside the SV-COM-
PANEL (i.e., they are completely interchangeable). Installers may use either connector or both
connectors in AF-5000 installations. Using both of these connectors allows installers to “daisy-
chain” another Advanced-SV Network module that may be co-located behind the panel.
Electrical Connections
Harness Construction
Because the SV-COM-PANEL connected to SV-COM-T25/T8 can be mounted in a variety of locations,
the harness length requirements will vary from airplane to airplane. Therefore, AFS does not supply
pre-manufactured harnesses. Instead, your SV-COM-T25/T8 includes connectors and pins to generate
a wide variety of harness configurations. Refer to the sections below for detailed wiring information.
The AF-COM-PANEL has two (electrically identical) D9 male connectors for connection to Advanced-SV
Network and one D15 male connector for connection with the SV-COM-T25/T8 and an optional
Frequency Flip/Flop pushbutton input.
The SV-COM-T25/T8 Transceiver has one D25 male connector for connection to the AF-COM-PANEL,
power, audio, and Push To Talk (PTT). A single TNC coaxial connector attaches to the antenna.
