Installation and Operation, cont’d

2 — SOG (sync on green)

On — The interface outputs sync on green.

Off — The interface outputs both separate horizontal and vertical sync (on the H and V connectors) and composite sync (on the S connector) for RGBHV or RGBS, respectively.

3 — Serr (serration pulse) — Many LCD and DLP projectors and plasma displays, must have serration pulses removed from the sync signal in order to be displayed 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.

4 — Neg Sync — This switch controls sync polarity.

On — Both the horizontal and the vertical sync signals are forced to negative polarity on output.

Off — Output sync polarity follows (is the same as) input polarity.

5 — V Sync Width (vertical sync pulse width) — For some digital display devices, if no picture appears, the picture cuts in and out, or it is scrambled, try adjusting the output vertical sync pulse width or switching from ADSP to DDSP.

On — The vertical sync pulse is narrow.

Off — The vertical sync pulse is wide.

6 & 7 — 75 Ohm (video input termination) — DIP switches 6 and 7 provide termination for video inputs 1 and 2, respectively. Video termination can be accomplished by using a laptop breakout cable, by connecting a termination adapter or a local monitor to a monitor breakout cable (MBC), by using an MBC buffer cable, or by setting a termination switch on the interface.

DIP switches 6 and 7 provide a termination method to prevent blooming when a monitor breakout cable is used but no local monitor or termination adapter is connected.

On — The interface provides 75 ohm video input termination.

Off — The interface provides high Z (high impedance) video input termination.

8 — No Backlight — This switch controls illumination of the LCD backlight.

On — The LCD backlight is off, except for three seconds at power-up.

Off — The LCD backlight is on while a signal is present at the selected input.

6BNC output connectors — These female BNC connectors are for red (R), green (G), and blue (B) video output, and

horizontal (H), vertical (V). and composite (S) sync output.

7Remote control connector — Connect a contact closure remote control device or an RS-232 device (control system or PC computer) to this 9-pin D female connector for remote switching between inputs.

Software for RS-232 control is included with the interface. See chapter 3, “Remote Control” for details.

8Stereo audio output connector — This 3.5 mm, 5-pole captive screw connector is for balanced audio output. See “Cabling” for a wiring guide.
