DIP switches — This bank of DIP switches is used to configure
the interface. The switches control:
• DDSP or ADSP
• SOG (sync on green)
• Serration pulses
• Vertical sync pulse width
• Mono or stereo audio
• Backlight illumination.
• Monitor ID bit termination
N To set the sliding-type DIP
switches, use a Tweeker or small screwdriver to slide the
switch to the on/up/closed or off/down/open position.
The default for all DIP switches is Off (down).
1 — DDSP
DDSP disables all sync processing. This feature may be
necessary for digital display devices such as LCD, DLP
(digital light processor), and plasma displays. Use this
option if the image is not displayed properly after other
options, such as serration pulse and video termination
changes, have been tried.
Up — The interface uses DDSP instead of ADSP. DDSP
does not process the sync signal.
N DDSP disables the horizontal and vertical centering
controls.
Down — The interface performs sync processing
operations, such as centering, with ADSP.
2 — Sync on green
Up — The interface outputs a composite sync signal on top
of the green video signal (SOG) via the G output connector
(RGsB).
Down — The interface outputs separate horizontal and
vertical sync (on the H and V connectors) and composite
sync (on the S connector) for RGBHV or RGBS.
3 — Serration pulses — Many LCD and DLP projectors and
plasma displays will not display properly if serration
pulses are present in the sync signal. Flagging or bending
at the top of the video image is a sign that the serration
pulses should be removed.
