• The input cable should be no more than 40 meters long and the
output cable no more than 5 meters long.
• Make certain that the 1391A is receiving power by looking at the
power LED.
• Attempt to isolate the problem by rst connecting the source
device directly to the destination device using the same cables you
are using with the expanded system.
• Premium cables are required for maximum distances; be sure the
cables provide low loss, high bandwidth signal handling.
• Inspect the cables for damage.
• Try using a cable two meters or less to varify that the units work
together under optimal circumstances. If you are unable to obtain
a signal using this simplied path, suspect the cables, the source
device or the destination device. Remember that HDMI devices
communicate with one another so the source device and all
destination devices must be fully HDMI capable. In addition, HDCP
encryption requires processing dependent on the equipment you
have connected to both the source and destination devices.
If the problem still persists after trying the above suggestions,
