Introduction
This is the replacement control console for the DXE-TFS4-series Hybrid Four-Square Controllers.
The DX Engineering Four-Square Control Console four directional momentary contact switches,
an Omni switch, and four green LED's (light emitting diodes) to show the systems current transmit
and receive direction.
Features
Drop in control replacement for other vertical antenna transmit four square systems providing
instant switching to one of four directions.
Antenna pattern directional selection switches and indicators
•One green LED illuminates to indicate which single direction has been selected. All four
LEDs are illuminated when OMNI is selected.
•Momentary contact push button switches below each LED select a single direction,
providing instant switching of directions without rotating a switch through unwanted
positions.
•White notepad blocks for writing the direction corresponding to each switch position.
•When OMNI is pushed, all four antennas are selected to produce an omnidirectional antenna
pattern and all four LEDs are illuminated. The omnidirectional option in the DXE-CC-
4SQR Control Console is only functional when using the control console with DX
Engineering Transmit Four Square systems.
When pushed again, the controller will return to last selected direction.
While in the OMNI mode, a new direction may be selected immediately by pushing its
corresponding switch.

LED brightness
The LED brightness may be set by pushing and holding the OMNI button for several seconds.
While holding the OMNI button, all the LED’s will be illuminated and then start flashing. Release
the OMNI button. The LED’s will continue to slowly flash and display four brightness settings (1
through 4). Select the desired brightness level by pressing the corresponding red switch button.
All four LEDs will then show the selected brightness setting. Press the OMNI button again to store
the new brightness setting.
Note: The controller stays in the omni mode while adjusting LED brightness.

Power ON Relay Exercise
The Transmit Four Square Control Console has a factory default program installed to exercise the
relays throughout the system when power is turned on. When the unit is properly connected and
power is turned on, the first and last LED will blink for approximately 6 seconds. While the LEDs
are blinking, all of the relays in the system are being turned on and off to ensure the relays are kept
in peak operating performance. During this routine, if any position push button switch is pressed,
the routine will stop and the system will return to the last position that was selected prior to the
system being turned off.
The operator can manually turn this routine on or off by pressing a sequence of front panel buttons.
To turn the factory default OFF:
1. Turn power ON. Wait until the first and last LEDs stop blinking.
2. Press any two of the pushbutton switches simultaneously and hold them in (LEDs will start
to blink) until the blinking stops. The factory default is now turned off. If you turn power
OFF, wait about 8 seconds (allows internal capacitors to discharge), then turn power ON, the
system will not run the relay exercise routine.
To turn the factory default ON:
1. Turn power ON.
2. Press any two of the pushbutton switches simultaneously and hold them in (LEDs will start
to blink) until the blinking stops. The factory default is now turned on. If you turn power
OFF, wait about 8 seconds (allows internal capacitors to discharge), then turn power ON, the
system will run the relay exercise routine as described above.
When the "RADIO" signal is grounded you are in Transmit mode. If you press any of the
pushbutton switches, they will flash and the unit will not switch positions until you go from
Transmit to Receive mode. This avoids 'hot switching'.

Four Square Control Console Direction Label
A custom label with various compass directions is included for the Four Square Control Console.
You may either write the directions on the white blocks that are on the face of the Four Square
Control Console, or you can use the custom label that is included. The number one (default)
position on the Transmit Four Square Controller is the first red push button on the left.
Depending on your antenna set up, you can cut the desired compass directions from the label, peel
the back off, and place the label on the Four Square Control Console.
This is the typical set up for North America
# 1 is NE - #2 is SE - #3 is SW - #4 is NW

 12 VDC
A standard 2.1 mm plug connection for 12 Vdc. The current draw ranges from 30
mA to 700mA depending on the direction selected. If station power is used, it must
be 12 Vdc at 1 amp (fused) minimum. An optional 12 Vdc at 1 amp wall
transformer supply DXE-PSW-12D1A is available.
Outer connection is GROUND Center Pin is input for +12 Vdc.
A 2.1 mm power cord is supplied with unit. The wire with the white stripes is the +12 Vdc.
AMP
RCA type connector. If you are using a linear amplifier, the keying line should be routed through
the Four Square Control Console. This jack connects to your amplifier's keying or relay line input.
The keying signal has essentially no delay on pass through. If you switch antenna positions while
transmitting, the controller waits until you stop transmitting before switching antennas. Once the
controller starts to switch antenna relays, amplifier keying signals are inhibited until switching is
fully completed.
The controller always waits 30 ms before restoring amplifier control signals after any antenna relay
transfer.
The AMP circuit is capable of switching up to 75 volts open circuit (receiving) and can safely sink
500 mA maximum current when pulled to ground (transmit). This will handle most modern
amplifiers. It will not handle high voltage relays, AC relays, or negative voltage keying systems. If
you have such systems you probably already have a relay line buffer. Simply install that buffer
between the amplifier and this jack.

7
RADIO
RCA type connector. Connect this jack to your transceiver's amplifier keying, TX, or relay (RLY)
output even if you are not using an amplifier. This is a normally open connection that must be
pulled to ground. It accepts any open voltage up to 20 volts positive and sources 15 mA when
pulled to ground. It nominally supplies 12 Vdc positive open circuit. Anything below +2 Vdc is a
valid logic low, anything above +3 volts is a valid logic high.
While the "RADIO" input is grounded (transmit mode), if you press any of the pushbutton switches
the corresponding LED(s) will flash and the unit will not switch positions until you stop
transmitting. This avoids 'hot switching'.
Connector
Five wire connector block labeled G A B C G. Use DXE-CW9 CAT 5 UV resistant cable (or
equivalent) is recommended and it also has a PE (polyethylene) jacket for long lasting direct burial
to make the connection from the Transmit Four Square Control Console to the DX Engineering
Transmit Four Square System Phasing Unit. Wire A to A, B to B, C to C, and either G to either G
(both Gs are Ground).
For other systems that usually require a 3 conductor cable, we suggest the use of COM-CW4 Four
Conductor Control Cable four conductor control cable (recommended to allow for future upgrade
to DXE-TFS4 system)
Output current is 700 mA maximum on any or all ports. The output is relay protected for maximum
lightning and RF protection. This device is internally protected against short circuits.
The DXE-CW9 CAT5 cable has #24 AWG wire. Based on current and voltage drops, CAT 5
cable is capable of running 400 feet from the Four Square Control Console to the Four
Square Phasing Unit.
For control cable runs from 400 feet up to 750 feet, doubling up the wire pairs of the DXE-
CW9 CAT5 cable (two wires per connection) will effectively make the wire gage go from 24
AWG to 20 AWG, thus allowing longer runs between the Four Square Control Console and
the Four Square Phasing Unit.
This controller is compatible with other 12-15 volt dc four square systems. The output voltage
always equals the supply input voltage. It counts BCD from zero through 4, giving 5 total positions.
Output A Output B Output C
Position 1 000
Position 2 +12 to 15 Vdc 00
Position 3 0+12 to 15 Vdc 0
Position 4 +12 to 15 Vdc +12 to 15 Vdc 0
Omni 00+12 to 15 Vdc
