Description of Equipment

Split Screen
Section III
The Model DD618CS provides five different versions of split screen, mix (overlap), or subtraction
functions for on e or two live Single-Link DVI-D (HDMI) video signals.
HDMI signals at the inputs are acceptable provided they are not HDCP Encrypted. The DD618CS
will not pass any audio that may be present in an HDMI signal.
The Model DD618CS accepts one or two DVI-D Single- Link Video inputs, performs the userselected split screen, mixing, or subtraction function, and provides a DVI-D Single-Link Video output for display
on a compatible monitor.
The DD618CS, constructed in an ABS plastic and aluminum chassis with an internal EMI shield
coating, is free standing with a sloping face for bench top use. It requires an external power supply to provide 5
Volts DC regulated, 1.5 Amps, at its 5.5x2.5mm coaxial power connector.
The Input/Output connectors are physically compatible with all DVI cables. The signal must be
DVI-D Single Link or HDMI without HDCP Encryption. Passive adapters and cables to interconnect DVI and
HDMI equipment are widely available. Generally, cameras are free of HDCP but DVD, Blu-Ray, and Satellite
sources are frequently encrypted. If a source is found to be encrypted, setting its output resolution to less than 720p
should deactivate the encryption.

Power: Coaxial 5.5mm x 2.5mm
Connect a camera or other source of a DVI-D or HDMI video signal to
the A “input” connector nearest the power connector on the rear of the
DD618CS. This input must always be used. If the video source provides
HDMI, a simple HDMI-DVI adapter or cable will be required. HDCP
encrypted video is not permitted and any audio will not pass through the
DD618CS. Use of the B “input” connector for a second source is optional.
When using both inputs, the sources must provide signals with identical
resolution specifications.
Connect a DVI-D video monitor to the “output” connector. HDMI
monitors are also suitable with use of a DVI-HDMI adapter or cable.
Connect the coaxial power input to a regulated 5VDC, >1500mA, center
pin positive regulated power source. The “Input A OK” LED should appear
steady. If the LED flashes, power is present but the signal at the video input is
absent, encrypted, or otherwise incompatible.
If using the DD618CS with only one video source, press the “Input”
button to cause either of the LEDs in the “A Only” column to light. If using two
video sources either “A Only” or A vs B” input modes may be used.
If using both inputs, both DVI Input connectors must be connected to DVI
sources of identical resolution. Check that either the “A vs B” or “B vs A” LED
is lighted. If not press the “Input” button. The “Input A OK” and “Input B OK”
LEDs should be lighted steadily, indicating valid input signals.
Split-Screen Tap the “Mode” button until a “L|R Squeeze”, “L|R”, or
“T/B” LED lights. Press the “Sub-Mode” button to select the desired type of
Split-Screen, as indicated by one of these three LEDs. For “L|R” and “T/B”
sub-modes, adjust the split position using the knob. The position and visible
portions of the inputs can be swapped by pressing the “Swap” button to select
“A vs B” or “B vs A”. Either input can be frozen by pressing the “Freeze A” or
“Freeze B” buttons.
Pressing the “Input” button to obtain the “A Only” function will put the A
input on one side of the split and the A input delayed by one frame on the other
side. Pressing the “Freeze A” button will freeze only one side of the split so
that a portion of live A can be displayed with a portion of frozen A.
Mix To obtain a double exposure display, tap the “Mode” button until the
“Mix” LED lights. The amount of each input present in the display can be
adjusted with the knob. These amounts can be swapped by pressing the “Swap”
button. Either input can be frozen by pressing the “Freeze A” or “Freeze B”
Pressing the “Input” button to obtain the “A Only” function will mix the A
input with the A input delayed by one frame (to little effect). Subsequently
pressing the “Freeze A” button will mix live A with frozen A, thereby making
positional changes noticeable and quantifiable.
Subtract To compare DVI video pictures by subtracting one from the
other, tap the “Mode” button until either the “Subtract” LED or the “Absolute
Value” LED lights. Select between “Absolute Value” or “Subtract” by tapping
the “Sub-Mode” button.
“Subtract” gives Gx(A/2-B/2)+50%. Therefore, areas of no difference
yield a 50% gray, areas where A is brighter than B yield more than 50% , and
areas where A is darker than B yield less than 50%. Pressing the “Swap” button
reverses the effects of A and B. “G” is gain, set by the knob, useful for setting the
contrast of the resultant picture.
“Absolute Value” gives Gx|A-B|. Therefore areas of little difference are
dark and areas of great difference are bright. Since |A-B=|B-A|, the “Swap”
button has no effect.“G” is gain, set by the knob, useful for setting the contrast of
the resultant picture.
Pressing the “Input” button to obtain the “A Only” function will subtract
the A input from itself delayed by one frame. Comparing successive frames in
this manner is very effective for showing only movement or change. Motionless,
unchanged objects are invisible.
View Either input can be viewed directly, regardless of other selections, by
pressing their respective “View” buttons.
Freeze Either input can be frozen. If using only the A input, the
Comparator will treat frozen A as one video source and live A as the other. Only
one input can be frozen at a time.
