Step 7 — Contact closure

For contact closure, connect an optional contact closure device to the front panel 5-pin, captive screw connector. Making contact closure between pins A and B transmits a channel signal through the rear panel RS-232 port. The RGB 580xi SI/CCSI AAP models provide one-button contact closure operation. Wire the male connector as shown below on the left. The Extron VGA and control cable assembly comes with the male control connector prewired, as shown at right.

serration pulse output, SOG (sync on green) output, vertical sync width,

and moving it down sets it to Off.
and moving it down sets it to Off.

NThe default for all DIP switches is Off (down).

1 — DDSP (Digital Display Sync Processing) — This feature may be necessary for digital display devices such as LCD, DLP (digital light processing) and plasma displays. Use this option if the image is not displayed properly after other options, such as serration pulse and vertical sync pulse width, have been explored.

On — The interface uses DDSP instead of ADSP. DDSP does not process the sync signal.

NDDSP disables the horizontal shifting control.

Off — The interface performs sync processing operations, such as centering, with ADSP.

2 — Serr (serration pulse) — Many LCD and DLP projectors and plasma displays must have serration pulses removed from the sync signal in order to display properly. Flagging or bending at the top of the video image is a sign that the serration pulses should be removed.

On — The interface outputs serration pulses in the vertical sync interval. Off — The interface does not output serration pulses.
