NOTE: The missing pins on the included DVI cable are not required for the single link
of DVI-D data supported by the FOXBOX DVI. The analog video pins are not
connected. All of these unused pins are shaded gray in the figure above.
DVI signals run at a very high frequency and are especially prone to errors caused by 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
FOXBOX DVI transmitter or the output of the FOXBOX DVI receiver.
• Use only the cable designed for DVI signals that is supplied by Extron.
• Limit or avoid the use of adapters.
• Use only cables specifically intended for DVI or HDMI signals. Use of non-DVI or non-
HDMI cables or modified cables can result in a missing video output.
