Installation and Operation, cont’d
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 12V power supply into this
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.

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
Alternatively, an Extron P/S 100 Universal 12VDC Power Supply can power up to six RGB 190F or RGB 192 interfaces using only one AC power connector.
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.

9Stereo audio output connector (RGB 192 and 198 only) — Connect an audio device, such as powered speakers, to this 3.5mm,
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.
