high quality 75-ohm “flooded” RG-6 type coaxial cable is
recommended. Flooded style cables have the distinct advantage of automatically sealing small
accidental cuts or lacerations on the jacket. Flooding also prevents shield contamination and the
coaxial cable can be direct-buried. Moisture coming into the shield often occurs at
the connector and can cause increased system noise. For superior watertight
connections, use
DXE-SNS6-25
Snap-N-Seal connectors. Weather-tight Snap-N-
Seal connectors CANNOT be installed with normal crimping tools or pliers. The use
of the
DXE-SNS-CT1
installation tool is
available from DX Engineering.
The F type ANT connector on the
DXE-FVC-1
is used to connect the receiving antenna feedline.
The appropriate switching voltage is applied through the feedline by the
DXE-FVC-1
. It is critical
that the feedline connectors remain dry and you do not place any intentional DC shorts or opens on
the feedline between the
DXE-FVC-1
and anything being controlled. This includes lightning
arrestors, splitters or any other accessory not intended for feedlines carrying power or control
voltages. The radio connections go to the receiver using either the type F or RCA phono connector.
The
DXE-FVC-1
requires 12 Vac to operate. Connect the included wall transformer to the 2.1 mm
barrel plug on the
DXE-FVC-1
labeled "12 VAC IN" .
Control connections for the

are made at the removable, green 5-terminal
screw-type connector. Do not attempt to solder wires to this connector. Remove
1/4 inch of insulation from each 16 to 24 gauge control wire, insert the wires in the
appropriate screw terminal. When tightening ensure the connection is secure
against the wire and not the insulation. Be certain that adjacent wires are
positioned to eliminate the possibility of shorting. Stranded wire should be tightly
twisted or very lightly tinned before insertion. Open terminal slots on the
removable green connector by turning the screws counter clock-wise before the
wire ends are inserted. Do not force the screw beyond the stop. Tighten each
screw securely clock-wise without over-tightening.

Input/Output Logic and Connection Examples
The
DXE-CC-8A
Control Console may be used to provide the voltage or a user supplied switch
may be used to provide the voltage or grounding, required by the
DXE-FVC-1
input in order to
control the output. The following tables show the input and output combinations for both schemes.
Each input state results in a different output voltage thru the ANT type F-connector and on the OUT
supplemental terminal per
Table 1
. Note the LED indications.
