Pre-installation testing/troubleshooting
Before completing the installation, test the system to make sure
that the connections and interface settings are correct.
1. Turn on the input device(s) (computer) and output
device(s) (projector and/or monitor). The image should
now display on the screen.
2. If the image is not displayed at all, double-check cable
connections, and ensure that all devices have power and
are turned on. For the RGB 500 series and RGB 508 series,
try changing the video termination toggle switch setting.
For the RGB 560 series and RGB 568 series, if no local
monitor is present, change the ID bit termination via the
front panel DIP switch, then reboot the computer.
3. If the image appears, but it looks scrambled or cuts in and
out, check the bottom and front panel DIP switch and
jumper settings. If all switches are already set to what
should be the correct settings for the connected input and
output devices, try different settings.
If the display device is digital (including LCD, DLP, and
plasma devices), try changing the vertical sync pulse width
(using the bottom panel jumper).
Next try changing the sync options (sync on green,
composite sync), sync polarity, or serration pulse options,
or switch from ADSP to DDSP. You may need to use a
combination of settings to achieve a proper display.
4. If the image appears and is stable, but it appears faint or
fuzzy, increase the output gain/peaking by changing the
top panel jumpers. If the image is too bright, decrease the
gain/peaking level.
5. If the image displays and is stable, but it has a greenish
tint, it may be a result of using video input with sync on
green. Incoming sync on green will not be stripped from
the green signal by the interface.
6. If the image appears and is stable, but it has ghosting or
blooming, change the video input termination. If
changing the termination doesn’t solve the problem, try
using a different input cable.
7. For further assistance, call the Extron S
3
Sales & Technical
Support Hotline.
8. Once the image displays correctly on screen, you may
adjust the horizontal centering using the front panel knob,
though this adjustment must be made each time the
interface is turned on.
Mounting the interface to the mounting bracket
1. Temporarily disconnect the computer video and audio
input cables and (for the RGB 560 series and RGB 568
series) the local monitor output cable from the front panel
of the interface.
2. For all models, attach the interface to the mounting
bracket with one 3/8” (0.95 cm) long #4-40 machine screw
(provided) inserted through the tab at the top of the
enclosure, as shown below.
