Extron electronic RGB 464XI, RGB 468 Mxi, RGB 468xi 8RGB 460xi Series Installation and Operation

Installation and Operation, cont’d

5 — Vertical sync pulse width — Try adjusting the output vertical sync pulse width if no picture appears, the picture cuts in and out, or the picture is scrambled.

Off — The vertical sync pulse is wide. On — The vertical sync pulse is narrow.

NYou can also try switching from ADSP to DDSP, as explained in the description for DIP switch 3 on the previous page.

6 — Negative sync — This switch controls sync polarity.

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

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

7 & 8 — Composite sync routing — These switches work together to route local monitor signals for Macintosh 13” monitors and all other Macintosh and VGA-type monitors.

NTo be valid, these switches must be set so that one is Off and the other is On. If both are set to On or Off, composite sync routing will not function.

7 (On), 8 (Off) — Sync routing to 15-pin HD local monitor for all Macintosh (non-13") and VGA monitors (default).

7 (Off), 8 (On) — Sync routing to 15-pin HD local monitor for a Macintosh 13" monitor.

BRGB video output connectors —­ Attach coaxial cables from the interface to the display device via these female BNC connectors. These BNCs are on red, green, blue, black, and yellow pigtail wires secured to the interface by the tie wraps.

For RGBHV output: R is red, G is green, B is blue, H is black, and V is yellow.

For RGBS output: R is red, G is green, B is blue, and S is black.

For RGsB output: R is red, G is green, and B is blue.

CGain switch —­ To compensate for cable resistance and capacitance, slide this switch to select the level of video gain that yields the sharpest picture:

Normal (bottom position) — unity gain (no signal boost).

Medium (middle position) — mid-level peaking and gain.

Maximum (top position) — maximum amount of peaking and gain. (Select this for use with longer cables.)
