- Page 2 It is used to control receive antenna switching devices through the feedline or on a two conductor control cable. The DXE-FVC-1 converts +12 Vac voltage input to fuse-protected 0V, +12 Vdc, −12 Vdc and 12 Vac output voltages. The voltage output of the DXE-FVC-1 is simultaneously sent on the receive feedline through the ANT port F connector and on the OUT pin of the removable 5-terminal rear- panel connector for use with a two-conductor control cable.

Page 4: Installation
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. -

SP4T rotary switch or a push-button switch arrangement. Note: The DXE-FVC-1 must be powered by 12 Vac in order to operate no matter which way JMP1 is set. BCD control interface systems require a 3-conductor control cable. 1-of-4 logic requires a 4- conductor control cable. - Page 6 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.

This is accomplished by swapping the POSitive and NEGative wires on the DXE-FVC-1 unit for the configuration examples in Figures 7, 8 and 11. The polarity information is clearly noted on each diagram in the small tables labeled "Control Cable Wiring". - Page 8 RMS or average reading DVM, the normal DC output of the DXE-FVC-1 will indicate a nominal +/– 6 Volts. The AC voltage will measure 12 Vac. The above diagram is the 1 of 4 grounding logic hook up scheme using...

- Page 11 Figure 6 shows a DXE-FVC-1 Feedline Voltage Coupler used to supply controlling voltages for a Four-Direction Beverage System using two DXE-RBSA-1P Reversible Beverage Systems, along with a DX Engineering DXE-RLS-2, 2-port receiving antenna switch, to build a four direction Beverage system using a single feedline. One or more DXE-RLS-2’s can be used to expand larger Beverage arrays and share the feedline back to the operating position.

- Page 13 Figure 8 uses a DXE-FVC-1 Feedline Voltage Coupler to supply the switching voltages for a system that has four different receive ports using three DXE-RLS-2 Two Port Receive Antenna Switches, one modified internally (refer to the DXE-RLS-2 manual). This four position switching system may be used for four antennas or four radio receivers.

Have you ever sealed a piece of electronic gear with it -- then opened it some time later to find that it had still managed to become corroded inside? Guess what? It's not the rain that corroded it - It's the RTV! Normal RTV gives off acetic acid when it cures.
- Page 19 DXE-900031 - Automatic Wire Stripper/Crimper/Cutter, 24-10 Ga. Our DX Engineering wire stripper uses a spring-loaded design to make quick work of wires ranging from 24 to 10 gauge. Just insert the wire, squeeze the handle, and listen for the click. That’s the sound of another perfect wire stripping job performed in about 2 seconds- a fraction of the time it takes your pocket knife to do the same job.
