Installation
Many monitors will not support all of the resolutions and refresh
rates shown. If you get no display, try a different rate.
c.
Install a blank panel (included in the rack kit) or another 1U
half-rack unit on the unused side of the rack.
3.
4.
Connect the input, loop-through and output cables. See Rear Panel
Connections and Controls.
SOG (Sync on Green) On/Off switch— Set this switch to the On
(up) position to enable SOG for RGsB video.

The maximum permissible length of the DVI input and output
cables is 16.4 feet (5 meters). Ensure that the cables do not exceed
the maximum permissible length, otherwise images may be
distorted or missing. Extron does not guarantee signal integrity
beyond 16.4 feet.
Set this switch to the Off (down) position to disable SOG for
RGBS or RGBHV video.
AC power connector — Plug a standard IEC power cord into this
connector to connect the converter to a 100 to 240VAC, 50 Hz or
60 Hz power source.
Configure the DDC, Output Resolution, and SOG switches. See
Rear Panel Connections and Controls.

•
At the control’s midpoint, the converter outputs video at 0.7
volts p-p (unity level).

Select a level setting of 0.7 volts and above to compensate for the
signal level decrease that occurs with long cables. Set the level at
the maximum setting for cable lengths over 500 feet.

compensate for detail (mid- and high-frequency) loss from low
bandwidth system components or capacitance in long cables. The
minimum setting (at the counterclockwise limit) provides no
peaking. The maximum setting (at the clockwise limit) provides
100% peaking. Adjust this control while viewing the displayed
image to obtain the optimum picture sharpness.

The computer reads the DDC on power up to determine the direct
digital video resolution and refresh rate to output. Ensure that
the local DVI monitor and the RGBHV monitor can both display
the selected resolution and refresh rate, otherwise images may be
distorted or missing.
• Use only the cable designed for DVI signals supplied by Extron.
• Limit or avoid the use of adapters.
• Use only approved DVI/DFP connectors.
Ensure that the computer and local DVI monitor are connected to
the DVI-RGB 100, and the DVI-RGB 100 and local monitor have
power applied, before applying power to the computer. If the other
devices are not turned on before the computer is, the image will
not appear.
Use only cables specifically intended for DVI or DFP
interfaces. Use of non-DVI or non-DFP cables or modified
cables can cause the DVI-RGB 100 to fail.

DVI/DFP signals run at a very high frequency and are especially prone
to bad video connections, too many adapters, or excessive cable length.
To avoid the loss of an image or jitter, follow these guidelines:
• Do not exceed 16.4 feet (5 meters) on the input or buffered loop-
through of the converter.
