DIP switches — This bank of DIP switches, as illustrated below,
controls sync on green output, composite sync output, DDSP
(Digital Display Sync Processing), serration pulse output,
vertical sync pulse width, and composite sync routing. Moving
a switch up sets it "On" and moving it down sets it "Off".

N The default for all DIP switches, except for switch 7, is
Off (down).
1 — Sync on green
Off — The interface outputs separate horizontal and
vertical sync (on the H and V connectors) for
RGBHV.
On — The interface outputs sync on green (RGsB).
2 — Composite sync — This switch controls composite sync
output.
Off — The interface outputs RGBHV or RGsB video.
On — The interface outputs combined horizontal and
vertical sync for RGBS.
3 — DDSP (Digital Display Sync Processing) — This feature
may be necessary for digital display devices such as LCD,
DLP, and plasma displays. ADSP is the default. If the
image is not displayed properly after other options, such as
serration pulse (4) and vertical sync pulse width (5), have
been explored set this switch to On.
Off — The interface performs sync processing operations,
such as centering, with ADSP.
On — The interface uses DDSP.
N DDSP disables the horizontal shifting control.
4 — Serration pulse — Many LCD, DLP projectors and plasma
displays must have serration pulses removed from the sync
signal in order to display the image properly. Flagging or
bending at the top of the video image is a sign the serration
pulses should be removed.
Off — The interface does not output serration pulses.
On — The interface outputs serration pulses in the vertical
sync interval.
