2.3 Typical
Interfaces
2.3.1 Video Input (Analog)
Typical interfaces include various types of video source equipment.
This unit is capable of interfacing and accepting input from all Audio
International and standard Commercial-Off-The-Shelf video source
equipment including but not limited to: Camcorder, Live-Feed
Camera, DVD, VCP and VCR players as well as Moving Map
Systems (i.e., Airshow, JetMAP, etc), and Personal Game
Systems. All video inputs have configurable 75
Ω
input termination.
All common video standards (i.e. NTSC, PAL, SECAM) are
supported. Video signal is composite (CVBS).
2.3.2 Video Output (Analog)
Typical interfaces include various video distribution and/or signal
manipulation devices. This unit is capable of interfacing and
providing output to all Audio International and standard
Commercial-Off-The-Shelf video devices and/or equipment
including but not limited to: Video Crosspoint Distribution Modules
(i.e., A/V-9691, AV-3232), LCD display monitors, Plasma display
monitors, Projectors, Personal Display Devices (i.e., Sony
Glasstron) and Touch Screen ECU Modules. The video output is a
series 75
Ω
back-termination. Unit has a fixed video signal gain of
two, and is intended to drive a 75
Ω
cable into a 75
Ω
input.
2.3.3 Discrete Interface(s)
Typical interfaces include existing aircraft and Commercial-Off-The-
Shelf control and/or indication devices and systems. This unit can
interface, accept, and provide input to and from all such devices
and systems incorporating similar interfaces for communication,
control, and/or status indication. All discrete inputs are ground-
active and optically isolated. Approximately 5mA of current activate
the input. Sufficient input ground potential is up to about +3V
relative to module’s power ground pin.
Status outputs are open-drain type, with customer-supplied current
limiting. Sink current of 10-20mA is recommended and should
never exceed 50mA.
