Extron electronic RGB 190FS, RGB 198 EU Ddsp, Mono audio output RGB 192 only, spare on RGB 190F

Installation and Operation, cont’d

4 — 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.

On — The interface uses DDSP, which does not process the sync signal.

DDSP disables the horizontal and vertical centering controls.

Off — The interface performs sync processing operations.

5 — No monitor (ID bit termination) — This switch controls the input assigned to the local monitor output and ID bit termination.

On — ID bits 4 and 11 are tied to ground.

Off — ID bits 4 and 11 are unterminated.

6 — Mono audio output (RGB 192 only, spare on RGB 190F)

On — Monaural audio is output on the left channel only. When mono is selected, the right and left inputs are combined and placed on the left output connectors.

Off — Normal stereo output.

7Power connector — Plug the external 12 V power supply into this 2-pole captive screw connector. The power supply is included with the unit. Figure 2-7 shows how to wire the connector.

Do not tin the stripped power supply leads before installing the captive screw connector. Tinned wires are not as secure in the captive screw connectors and could pull out.

Figure 2-7 — Power connector wiring

The two power cord wires must be kept separate while the power supply is plugged in. Remove power before continuing.

To verify the polarity before connection, check the no-load power supply output with a voltmeter.

8BNC output connectors — Connect a coaxial cable between the display (projector or monitor) and these rear panel BNC connectors.

For RGBHV (separate H and V sync) output, connect the cables to five BNCs.

RGBHV

For RGBS (composite sync), connect the cables to four BNCs.

RGBS

For RGsB (sync on green, SOG), connect the cables to three BNCs. Also select the SOG option on the front panel DIP switch (see item 6 , Dip switches, in this chapter.

RGsB

9Stereo audio output connector (RGB 192 and 198 only) — Connect an audio device, such as powered speakers, to this 3.5 mm, 5-pole captive screw connector for balanced or unbalanced stereo or mono audio output. Stereo or mono output is determined by a DIP switch setting on the front panel. See DIP

switch 6 in item 6 , DIP switches, on the previous page.

When mono is selected, the right and left inputs are combined and placed on the left output connectors.

Balanced or unbalanced outputs are available for mono and stereo.

The illustration here shows how to wire

the captive screw audio connector. The connector is included with the interface, but

you must obtain the cable. Insert the wires into the appropriate openings in the captive screw connector. Tighten the screws on top to fasten the wires.
