Wiring:
A send
module (UDS-HDMI
or US-HDMI) needs
to be connected to a
Knoll receive module
(UDR-HDMI or UR-
HDMI) to work
correctly. The send
and receive module
are connected using two cat 5e or cat 6 wires using all 8 conductors in
each. Connection is made with the RJ45 connector (RJ45 plug not
supplied). Always use standard 568-A cat 5 wiring practices (shown
above). Using the correct wire pairs and polarity is
VERY
important.
Make absolutely sure the XA port on the send unit is connected to the
XA port on the receive unit. Likewise the XB port on the send unit is
connected to the XB port on the receive unit. Both wires are needed.
Please note the maximum cat5e or cat6 wire length for reliable
operation of 1080p is 115 feet or 35 meters.
Do not attempt
a longer length as it may not be reliable. For lower resolutions
such as 720p or 1080i the maximum length is 135 feet or 42
meters. Cat 5e and cat 6 wires should be as short as possible.
Never run the cat 5e or cat 6 wires near or along side high
voltage wires. If high voltage lines are near by cross the cat 5e
or cat 6 wires to them at 90 degree angles.
Never coil up cat 5e or cat 6 wires. This can increase the
inductance of the wire and may give an unreliable picture.
Connection to HDMI source equipment
: Connect the UDS-HDMI or
US-HDMI HDMI connectors with as short as possible HDMI cord to the
source equipment. Less than 2 meters (6’) is best. The maximum
length the HDMI cables to the input and output combined is about 35’
(10 meters).
Make sure a good quality RJ45 8-8 crimper is used
to
connect the RJ45 connector to the cat 5 wire. Poor crimping
and mismatched wires are the most frequent cause of
installation problems.
Power requirements:
The Knoll HDMI balun system requires a single
PS1205 power supply connected to the send or receive unit.
Note: If the cat 5 wire length exceeds 70’ (21m) we strongly
suggest connecting the power supply to the receive side only.
Note: The HDMI decora style and enclosure style
Models can be mixed or matched as desired.
Connection to the Projector, TV or other components:
Connect
short as possible HDMI cable from the receive balun to the projector,
TV or other component. The maximum length the HDMI cables to the
input and output combined is about 35’ (10 meters).
Setting the HDMI switch:
There is a switch on the receive unit that
adjusts the Knoll HDMI balun system. In our testing experience we find
that a setting of 1 or 2 for anything below 5 metres setting 3 for 5 – 21
metres and 4 is best setting generally for all 1080p material from 22 -
29 metres (98.43 ft), usually a setting of 6 or 7 for distances above 30
– 35 metres (115 ft). Feel free to experiment with other settings. To
see this effect turn a 1080p image on and try adjusting the switch.
Lower resolution images (480i/p, 720p, 1080i) are not affected as
much by changing the settings.
