Revision!E,!December!2009!
General Information
The DAPS440 is a Video/Audio Switcher which takes 4 composite sources, and
amplifies and switches each to 4 outputs. In addition, the DAPS440 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
The DAPS440 has 4 Audio & Video input source connections and four individual
Audio & Video output connections for each input. Switching is accomplished
with a ground switching system. The DAPS440 will support the installation of
four independent switches at four different seat locations. Each individual at
each of the four seat positions can independently access up to four audio and
video sources by pushing their button. Every time the button is pushed, the
audio and video source will sequence through sources 1, 2, 3 and 4.
For example, if you have installed our Moving Map, Glareshield Camera and two
DVD players, the DAPS440 can sequence output from Moving Map, to Camera,
to DVD1 and then to DVD2.
The DAPS440 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, 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 four holes are located two on each
side of the flange. It is sufficient to mount the display by two attach points. It is
recommended that you leave about ¼inch 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. The momentary ground is pined to the DB-15 to accomplish the
switch of the Audio/Video source.
Power
This is a 28VDC device that requires 1.0 Amps of power to operate.

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, [phone]). 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.
