Passive Baluns & Active
Amplifiers for transmission of
VGA &
Component-Video over Cat5 Twisted Pair Cable
up to
300 metres.
Use existing (or easily install) Network Cabling in Homes &
Businesses to cost effectively distribute VGA signals from
Digital Video Recorders,
Computers (PC
& Apple) &
Component-Video signals (YUV
RGB YCbCr YPbPr)
up to 135 metres (BalUn) & up to 300 metres (Active
Amplifier/Extender/Distributor). Split signals up to five
ways & distribute to multiple areas,
eliminate the cost & difficulty associated with cumbersome
inflexible Coaxial Cable.

For use with VGA-Dist4+1 (above) and in situations
where
Skew
is a severe problem, simply replace VGA-RX included in above with
this device to reduce/eliminate severe Skew.
Also suitable for use in pairs (Daisy-Chained) to extend VGA
transmission distance beyond 300 metres.
Ideal for situations where Cat5e, Cat6 & other Low-Crosstalk Cabling
has already been been installed, low crosstalk TP is fine for a LAN
but causes & exacerbates Skew when used for transmission of VGA
signals. Crosstalk reduction in Cat-5e & Cat-6 is achieved in part
by deliberately twisting the individual pairs in a 4 pair Cable at
different rates to reduce coupling, the consequence of this is that
pair lengths are unequal causing Skew.

Results may vary
depending on:
Resolution/Refresh rate,
Cable-Length and Cable
characteristics.
Output level of Source device (PC,
DVR) and input sensitivity of Receiving device (Monitor).
&
In particular the length of RGB pairs,
variations may cause Skew that will become more
evident as Cable-Length, Resolution and Refresh rate are increased,
Skew-Correct can be used to reduce/eliminate
Skew.
Some brands/models of Monitors are very sensitive to
sync levels and may function poorly.
Skew
If all three
RGB Pairs are of equal length Skew will not occur, however in
practice the number of Twists in each Pair does vary, this variation
affects the timing of the signals arriving at the Receiver resulting
in a horizontal displacement of the Red
Green Blue
images on the Monitor.
Skew
increases with Cable
Length, Resolution and Refresh rate, reducing these will reduce
Skew,
in most situations
Skew-Correct or
VGAskewRX
will eliminate or significantly reduce Skew.
