NOTICE
1.
Vanco High Speed HDMI cables are strongly recommended for use with this product to
ensure best results.
2. Incorrect placement of IR Blaster and Receiver may result in the failure of the unit.
Please check carefully before plugging in the IR accessories into the respective IR
sockets.
3.
If your HDMI display has multiple HDMI inputs, it is found that the first HDMI input [HDMI
input #1] generally can produce better transmission performance among all HDMI
inputs.
TROUBLE-SHOOTING
1. Best results are usually achieved when the source and display resolutions are the same.
If resolutions differ, the extenders will try to adjust the signal to match the resolution of
the HDTV with the lowest resolution. This will result in a picture with a lower resolution
on the other HDTV sets.
2.
If you do not get audio and video, access the “setup” menu on the TV to adjust the audio
and video settings. If the HDMI control circuit cannot establish a handshake, then there
usually will be no audio or video in addition to a blue or black screen with a statement
similar to “this protocol not supported” or “weak signal”.
3.
If the above mentioned messages display, reset the receiver by disconnecting the power
supply. You can also disconnect all of the HDMI and power cables, wait 15 minutes for
any voltages to decay and then reconnect all of the cables.
4.
If you are still encountering issues, attempt the “hot-plug concept. With all of the HDMI
cables disconnected, turn on the source and plug in the HDMI cable into it’s output,
then power up the Vanco unit and plug the HDMI cable into it’s input, finally turn on the
display and plug the HDMI cable from the receiver into it. This activates all of the devices
in corresponding order and results in a signal being plugged into a device that is on and
will attempt to connect the signal.
5.
Most of the major source and display manufacturers employ a proprietary control
channel to communicate between devices from the same manufacturer. Sometimes this
can interfere with the HDMI control circuit or the authentication of the signal. Call the
manufacturer if you experience this issue. Sometimes a player, an audio/video receiver,
or a cable/satellite box may not have the latest software update, usually this can be
downloaded from the manufacturer’s website.
6.
If you have problems with the IR control circuit, make sure that the IR RX pigtail is
plugged into extender receiver and pointed at the display, and the IR TX pigtail is
attached to the extender sender and pointed at the source.
