As default the distance is set to maximum 300 M. Changes in distance settings are
made inside the Tx Repeater/Rx300.
If the picture has visible vertical shadows it can be improved by adding internal or
external delay line.
To get the highest picture quality connect a monitor direct to the Tx units to calibrate
the EQ and Gain before moving on to the next repeater or receiver box.
After installation adjustments should only be carried out on the monitor settings and
Rx60/125/300 ends otherwise the pictures on the other boxes will change.
Video
No picture on the Tx1.
1) Is the Green LED lit on the unit? No power, no transmission
2) Bad picture quality with very long transmission lines—Daxten can, on special
order deliver Cat 5E cable optimized for VGA transmission. Adding a delay
line (skew delay compensator) will also help.
3) Is this receiver fitted with an UTP-in card ? Add one.
4) Is the transmitter first unit working? Check local out.
5) Check the cables.
6) No picture will be showed if you use the VGA input on a Tx fitted with an
UTP-in Module.
7) Check the UTP cabling if you have problems with the colours.
8) If the picture shakes and contains noise you have to isolate the problem by
removing the UTP cables to some of the UTP units in order to find the line and
box with the problems. Check the ground. Call an electric technician with
grounding skills and test equipment for proper grounding.
9) The UTP Cables are made the same way as used for networking
10) None of the cables for the Information system can be used to carry other data or
be connected to any networking equipment.
11) Noisy picture if ground problems occur over long distance. These problems are
solved by experiments with grounding the housings or adding ground loop
isolators. If the voltage potential is large enough, your equipment won’t be able
to handle the excess voltage and one of your ports will be damaged. You can’t
test for ground loops. You don’t know you have one until picture fails. A
ground loop is a current across a conductor, created by a difference in potential
between two grounded points, as in two buildings connected by a run of data
lines. When two devices are connected and their potentials are different, voltage
flows from high to low by travelling through the UTP cable.
