Thank you for purchasing the new ex•tend•it VDL•1000 by Gefen, Inc.
The VDL•1000 improves the quality of picture transmission over CAT5, CAT5e, or CAT6
UTPorSTPcables andmay beusedwithanyextender. CAT5/6cable hasbeen optimized
for network data transmission and has four separate twisted pairs each with a different
number of turns per unit length to reduce crosstalk between pairs. This results in each
pair being a slightly different overall length.
When this type of cable is used for high quality video transmission, usually the Red, Green
and Blue signals are each sent down a separate pair (within one 4-pair cable). This may
have a significant effect, similar to misconvergence, as signals take a slightly different
time to arrive at the receiving end and as a result suffer visible colour separation between
Red, Green and Blue.
This distortion is worse for higher resolution signals and is often called SKEW - the ef-
fects are removed by adding a short, wide bandwidth delay to the signals that arrive at
the monitor first.
Adding the VDL•1000 frequently results in much clearer pictures.
The unit is placed in series with the monitor lead and has three separate delay lines, each
switchable with 4 binary bits of 3nS so the delay is adjustable from 0 to 45nS in 3nS in-
crements.
The unit does not require a separate power supply.
