Installation and Operation, cont'd
Most laptop or notebook computers have an external
video port, but they require special commands to output
the video to that connector. Also, a laptop's screen shuts
off once that port is activated. See the computer's user's
guide for details, or contact Extron for a list of laptop
keyboard commands.
Audio inputs 1 and 2 — Connect the unbalanced stereo audio
2
sources (such as the computers or a CD player) to these 3.5 mm
mini stereo jacks for unbalanced audio input. Figure 2-7 shows
how to wire the audio jack.

other device to this 15-pin HD female connector.
BNC output connectors — Connect a coaxial cable between the

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

Audio output connector — Connect an audio device, such as
5
powered speakers, to this 3.5 mm, 5-pole captive screw
connector for balanced or unbalanced audio output.
Figure 2-8 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.

DIP switches — This bank of DIP switches is used to configure
6
the interface. The switches control:
• DDSP or ADSP
• SOG (sync on green)
1 2 3 4 5 6 7 8
• Serration pulses
• Vertical sync pulse width
• Monitor follows
• Mono audio left
• Auto-switching
• Backlight illumination.
The default for all DIP switches is Off (down).
1 — 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 instead of ADSP.
DDSP does not process the sync signal.
DDSP disables the horizontal and vertical centering
controls.
Off — The interface performs sync processing operations,
such as centering, with ADSP.
