General Information
The DAPS440-SW is a 4x4 Audio & Video input source distribution amplifier that will
remember and display four different audio/video input sources. In addition, the DAPS440-
SW supplies 3 Amps of 12VDC of power available for other cabin entertainment products
(i.e. Wireless Audio, DVD player, Glareshield Camera, or LCD monitors).
Front View
Additional Information
Traditionally, cabin entertainment switching equipment is very expensive to purchase and
can require long lead times depending on the complexity of the system. The cost for each
switch is about $1000. Flight Display Systems has designed a product that significantly
lowers the cost of switching, reduces lead times, and makes the overall installation simple.
Best of all, the operation of the equipment is very easy for the passengers to operate
As an example, if you have installed our Moving Map, Glareshield Camera and two DVD
players, the DAPS440-SW can sequence output from Moving Map, to Camera, to DVD1,
and then to DVD2.
The DAPS44-SW is set up so that all channels revert to input 1 upon power up (or power
cycle).
The DAPS440-SW is made of all metal components. DO-160 testing has been completed
and is available upon request.

Installation Instructions
All cabin entertainment equipment, such as the DAPS440-SW, should be installed on a
non-essential bus and have a dedicated circuit breaker. It is a requirement that a switch be
installed so that the pilot can de-energize the system should it become necessary.
There are six mounting slots located on the sides of the housing. Four holes are located at
the four corners of the back and two holes are located one on each side of the flange. It is
sufficient to mount the unit by two attach points. It is recommended that you leave about ¼
inch of space around the unit for air circulation.
Audio/Video inputs are paired and listed on the same side of the unit as the Power Input
DB-15. From left to right the video/audio inputs are line 1,2,3,4. Use the inputs
sequentially as you would like them selected by the operator.
On the opposite side of the unit is the output side. Here you will find four paired output
jacks.
Power
This is a 28VDC device that requires 1.0 Amps of power to operate.

Switch
The new DAPS440-SW works with an off the shelf low-cost, no lead time Eaton 4 position
micro switch (Eaton P/N 58210220) or Staco switch (P/N 982431). Each time the switch is
activated it cycles and displays the current equipment source (Example shown below:
“MAP, DVD1, DVD2, CAM”). The Eaton switch uses 28 volt lamps, and the Staco switch
uses LEDs.
The DAPPS440-SW will support the installation of four independent switches at four
different seat locations. Each time the switch is activated, it will illuminate the current
source selected.
The switch illustrated above is from Eaton. Eaton and Staco switches can be ordered from
Dallas Avionics (800-527-2581) and can be customized to the customer’s requirements.
Lead time is one week for customization. The DAPPS440-SW does not include the Eaton
or Staco switch.

Switch Wiring Suggestion:
The diagram below shows a suggested wiring of the switch. From the DB-25 connector,
use the Normally Open pin and a DC ground (switch common) to establish the switch
connection.
To control the indicators, supply 28V DC power to the common Anode of the indicators (or
the power side). Connect each Cathode (or ground side) for each indicator to the DB pins
as indicated in this manual.
If there is a ground difference between the unit and the aircraft, this might cause the
switches not to operate properly. The DB-25 connector includes 28V DC and ground to
supply to the switches if such problem arises.

Video Wiring Suggestions
All shields should be grounded to the connector at the source, and floating at the display.
Avoid routing video wiring parallel to:
•AC wiring
•Strobe wiring
•DC motor supply cables
•Inverter cabling
•Or any other potential noise source.
S-Video/Composite and Audio Wiring
Recommended cable for s-video/composite and audio purposes is PIC 75 Ohm Coax, P/N
V75268. This is a lightweight, flexible, and low signal loss cable which meets FAA
flammability requirements of FAR 23.1359(d), FAR 25.853(a) and FAR 25.869(a)(4).
Similar aviation coaxial cable can be used from other vendors, as well.
Some aircraft are prone to AC noise - we recommend adding to the composite source a
75Ohm video isolation transformer such as Deerfield Laboratory, Inc. Part No. 162-1
(www.deerfieldlab.com, (650) 632-4090). In most cases this should be added to the video
output of the source.
Power and Ground Wiring
22 AWG wire is recommended for Power and Ground applications.

Troubleshooting
Video Noise
Check for an incorrect ground in the installation wiring. See specific examples of video
noise below, or visit http://flightdisplay.com/Grounding.pdf
Snow or Sweeping Lines
Lines that slowly sweep up and down are a result of AC noise. This AC noise can be
generated by a power cart on the aircraft. Take the power cart off of the aircraft. Be careful
of inverter wiring, which can also cause noise. Stand off the wires, if necessary.
If snow or sweeping lines persist, it is possible that the ground is at an incorrect point in the
aircraft. Try moving the ground to another location.
No power to Monitor, or No video Input
• Verify correct wiring. Check the base receptacle connectors for possibly damaged pins.
• Check that the video source is:
1. Powered on,
2. In Play mode, and
3. Displaying video.
Color Distortion
• Adjust brightness and contrast settings using the buttons on the monitor.
Remote Control Inoperable
•Confirm that the infrared eye on the LCD screen is visible.
•Replace battery in remote control.
