Thank you for choosing the Galaxy ™ system, designed for Distributing and daisy
chain high-resolution video signals over long distances via CAT 5 cables. By choosing
Galaxy, you have assured that your installation is equipped for the ever-increasing
demands made in a modern computer-based information environment.
The Galaxy system allows the info-computer to transmit this monitor image to a
number of receiver monitors in large environments such as subway stations, bus
terminals, airports, restaurants, malls, banks etc.
The Galaxy Tx1 is a base unit with one VGA output and one UTP output.
The Galaxy Tx4 is a base unit with one VGA output and four UTP outputs.
The Tx1 and Tx4 can be fitted with different option cards:
• UTP-in Card for up to 125m distance
• UTP-in Card for up to 300m distance
• A skew compensator board
• Sound board on request and requirements
Features
• Up to 300 meters in one line without repeater
• Up to 1000 meters with 10 Galaxy Repeaters in 800 x 600 @ 75 HZ
• Compatible with the Galaxy Rx60 Receiver for building in and the external
Rx60, Rx125 or Rx300 version
• Sound or remote operation of monitors ON/OFF on request
Operation
The Galaxy is simple to operate, but need planning before installation, to obtain the best
picture quality.
Compatibility
This product has been tested with a wide variety of hardware. However, it is impossible
to guarantee correct operation with every monitor currently on the market.
The Galaxy is compatible with the following equipment:
• Monitor: VGA, SVGA, XGA, SXGA, UXGA
• Computers: all computers using a HD-15 VGA output and standard VGA signals
RGB and two sync signals H/V

Galaxy Rx60 DC jack connectors— There are two DC jack connectors on the Rx60,
both of which can accept power supplies giving between 9-20vdc. The second jack
connector is available for use in contexts where a TFT screen, for example, is powered
by a 19vdc mains adapter. Since the Rx60 only uses 200ma, the TFT mains adapter
will normally be able to power the Rx60 as well. This is done by plugging the DC jack
from the TFT mains adapter (possibly with the help of a DC jack adapter) into one of
the Rx60 DC jack connectors. A jack-jack cable, which must be obtained from a
stockist or constructed from components, can then be used to take the 19vdc current
from the Rx60 to the TFT screen. This obviates the necessity of a second mains adapter
for the Rx60.

Galaxy Transmitter and Galaxy receivers.
When planning large installations please chose the right boxes and configuration.
When working with Daisy chains please make a drawing with cable lengths of your
system and give the boxes a numbers so it is possible to locate the boxes on the
drawing. Write down the configuration for the box if it contains a delayline so you can
put in a spare box with the right settings.
Begin installation from the info-computer.
Connect a Galaxy Tx1 or Tx4 (without UTP-in module) to the Info-PC.
Put on a still test image on the info-computer.
A) Connect a Rx60 receiver to the first Galaxy. Connect a monitor to the Rx60;
adjust the R G B for the best picture.
B) OR Connect a Tx1/4 Repeater Station or a Rx125/300; adjust the EQ and Gain
for the best picture.
The Galaxy products are made in many versions for special requirements: With and
without UTP in modules, with and without delay lines.
The UTP in modules differ in equalizing: the 125M-module work with UTP lines up to
125M. For longer distances use the 300M Version with UTP-in for distances between
125 and 300 m
The 125M version has no inside distance switches.
The 300 version has inside switches for distance adjustment.
Galaxy Repeater station TX1/TX4 300M and Rx300
Please Notice! The distance of the cat5 cable is set by micro switches inside the Galaxy
Repeater 300M/Rx300.

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.
TROUBLE SHOOTING

12
How long distance is it possible to make one line?
The Tx1 and Tx4 has been tested with 900 meters without delay lines at 800x600. To
go long distance you need a delay-line compensator to restore the signal.
In information systems it is common to work in low resolution. Users are in distance of
the display and need larger types. Daylight makes it difficult to work with monitors and
displays outdoor. Using smaller displays needs larger types. Try reading your
information in two meters is it readable?
If you are running long distance and high resolution pictures with small text you might
see that Black don’t turn into White. The texts on the monitor have small shadows
Put on a test image on the central computer. The best test picture is made of red green
and blue lines above each other. If the 3 colour lines do not match on the monitors you
need delay-line compensating equipment.
The improvement can be made using an internal or external skew compensator.
The Tx1 and Tx4 repeaters can use an internal compensator type Galaxy-TXSK.
Maintenance and repair
The units do not contain any user-serviceable parts inside. Any malfunction of the unit
should be reported to a factory-authorised repair centre for service. Any discrepancies
in the operation of the unit according to this manual should be reported to the Technical
Support Department of Daxten.
Technical support
If you cannot determine the nature of a problem, please call Daxten and ask for
Technical Support.
If possible call from a phone located near the unit - we may be able to solve your
problem directly over the phone. If we cannot solve your problem, and the fault is
supposed to be in the unit, we will issue a Return Material Authorisation (RMA)
number that must appear on the outside of all returned products. The unit should be
double-packed in the original container, insured, and shipped to the address given to
you by our Technical Support representative.
