EVICES
Sound doesn’t seem to get through from the local site to the remote site or vice versa.
1. Check the audio cables, including those attached to your speakers. Are they
intact along their length and securely connected at both ends? Are all cables
running correctly from LINE OUT to LINE IN?
2. Is your sound card actually outputting anything? Check this by temporarily
attaching some speakers directly to the card.
Sound is distorted.
1. At what level is sound being output to the Extender? If it’s above line level
(5 volts peak-to-peak), sound will be distorted as it passes through the
Extender. The Extender doesn’t support devices that output above line level.
2. What type of speakers have you attached to the Extender? The Extender
doesn’t support the older, cheap, non-amplified speakers that could be
plugged into the “SPEAKERS” jack on old sound cards.
8.1.6 V
IDEO
The picture is not sharp, or is badly smeared.
1. The video compensation might not be set correctly. See
Section 6.4
.
2. Check the interconnect cable between the Extender’s Local and Remote
Units. Is it solid-core cable, rated as Category 5? (It might be possible to use
CAT5e at distances up to 120 m [400 ft.], but video will degrade if it’s run
across lengths of CAT5e greater than that.) Is the cable intact along its length
and securely connected at both ends? And is it wired correctly? (Compare the
cable’s specs with those listed in
Section 4.2.4
and its wiring with that shown
in
Appendix A
.)
3. Check the video-extension cabling, patch-panel video connections, and other
video connections in the system. Make sure everything is properly and
securely attached.
4. Are you using an LCD panel? You might need to reduce the refresh rate of
your graphics card’s output.
