Figure 8. HDMI Connectors
HDMI 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 HDMI transmitter or the output of the FOXBOX HDMI receiver.
• Use only the cable designed for HDMI signals that is supplied by Extron.
• Limit or avoid the use of adapters.
• Use only cables specifically intended for HDMI or DVI signals. Use of non-HDMI or
non-DVI cables or modified cables can result in a missing video output.
To securely fasten an HDMI cable to a device:
1. Plug the HDMI cable into the panel connection (see a in figure 9).
