Introduction

The DXE-EC-DVA is the 3 position controller used to control the DX Engineering Dual Vertical Array
systems (DXE-DVA series).

The DXE-EC-DVA offers the following features:

 Stainless Steel Housing
 Non-Skid feet
 On-Off toggle switch
 Three green LEDs indicate position chosen
 White blocks to mark your chosen directions
 Internal automatic resettable fuse
 Includes a 2.1 mm power plug for +12 Vdc power connection

Front and Rear Panels

On/Off toggle switch Control Wire Feed Through
Three Green LEDs Power Connection
3 Position Rotary Switch

The DC Input used is +12 Vdc. A 2.1 mm power cord is supplied with unit. The wire with the white
stripes is the +12 Vdc.

Outer Connection is GROUND, Center Pin is +12 VDC.
If station power is used, it must be +12 Vdc at 1 amp (fused) minimum. An optional

DXE-PSW-12D1A 120 Vac 60 Hz to 12 Vdc 1 Amp, fused wall transformer supply is
available.

1. Open the unit by removing the four (two per side) Phillips head screws to remove the cover.

2. Push the end of the cable through the control wire feed
through on the rear of the unit.

3. Three wire connections for the wire are made on the
green header (G-1-2). Loosen each terminal screw until it
is near flush with the top of the connector block as shown
to the right.

4. Strip approximately 1/4" insulation from the three
conductor wire ends.

5. Connect each wire to a terminal (G-1-2) by sliding the wire completely into the wire connection
hole. Using a small flat blade screwdriver, tighten the associated screw until the wire is firmly
gripped in place as shown below.

Take caution to ensure just the wire is clamped in place, not the wire's insulation which would cause an open
or intermittent connection. Do not over tighten the screw so much that the wire is cut instead of being firmly
gripped. Use the included Ty-Wrap on the inside of the unit to hold the cable from pulling outward as shown
above.

Control lines normally use good quality CAT5e cable (3 twisted pairs of 24 AWG wire) for runs up to 1000
feet. Typical DX Engineering control lines requirements are +12 VDC at 25 milliamps. Depending on the
number of control lines needed (usually 3) you can double up the twisted pairs of CAT5e cable, or use
control wire that is at least 22 AWG, allowing runs up to 1500 feet. If you use a cable with more conductors,
it is a good idea to tie the unused conductors to ground. For longer runs of control cable, use a line loss
calculator to ensure you supply the proper control levels needed.

Approximate BCD Control Line Lengths.

When connecting the cable to the DX Engineering Dual Vertical Array system, ensure your cable is wired
the same way at the other end to avoid un-necessary troubleshooting (G-1-2). Use the chart on the next page
to record which color wire is connected to each terminal connection.

Optional Items

DXE-CW4 - Four Conductor Cable, Sold per Foot

A high quality, PVC jacketed 4-wire control cable, COM-CW4 consists of 4 #20 AWG stranded copper
conductors. It may be used in a multitude of control cable applications, such as remote switching and
antenna rotators. Sold by the foot - order the length you need.

AC Adapter 12VDC/1000mA - DXE-PSW-12D1A

The DXE-PSW-12D1A is an AC Wall Transformer Adapter to furnish 12 Volts DC at 1000 mA from 120
Vac 60 Hz input, fused output. It features a standard 2.1 mm plug connection for 12 Vdc. Outer connection
is GROUND Center Pin is input for +12 VDC. Ideal separate power source for DX Engineering Antenna
Switch and Transmit Four Square Controllers, NCC-1, TVSU, DXE-MBV-ATU-1 Remote Antenna Tuner
Kit and most MFJ automatic antenna tuners
