Figure 1 - DXE-FVC-1 removable connector
The green connector on the rear of the
DXE-FVC-1
is a two part polarized connector. This
connector, for the control wires, is removed by pulling it straight off. This will allow easy wire
placement or servicing as needed. When pushing the connector back in place, ensure you press
straight inward. Refer to
Figure 1
.
Connections are made with a screwdriver; no soldering is required. Do not attempt to solder wires
to the connector, and do not over-tighten the screws. Remove 1/4 inch of insulation from each
control wire so the screw terminals tighten on the wire and not the insulation. This will also protect
adjacent wires from the potential of shorting together. Stranded wire should be tightly twisted or
very lightly tinned before insertion. Open terminal slots by turning the screws CCW (counter clock-
wise) before wire ends are inserted. Do not force the screw beyond the stop.
Connecting the
DXE-FVC-1
to a receive antenna system uses a standard type F connector. This
allows use of readily available 75-ohm coaxial cable and connectors, and protects the receive
system from accidental connection to transmitting equipment.
Installation
The
DXE-FVC-1
is typically mounted near the operating position so the LEDs are visible, but any
protected location with ambient temperatures below 150° F non-condensing (65° C) is acceptable.
The DXE-FVC-1 unit requires 12 Volts AC power.
The unit will
not
function properly if 12 Vdc is used on the input.
The included wall
transformer will provide 12 Volts AC power for the DXE-FVC-1.
A malfunction will occur if 12 Vdc is used to power the DXE-FVC-1.
Figure 2 - Transformer Label
The switched output voltages appear simultaneously on both the ANT feedline connector and the
rear panel OUT terminal on the 5 position green connector. The OUT terminal is used for
supplemental switching control output only and cannot be used to provide power to any unit.
NOTE:
The
DXE-FVC-1
uses 1/2-wave rectification for the DC control voltages. When
measuring the output using an RMS or average reading DVM, the normal DC output of
the
DXE-FVC-1
will indicate a n/– 6 Volts. The AC voltage will measure 12 Vac.
