Galaxy is a VGA/Video/Audio transmission system for Cat5 cables. The system supports up to 300 displays along 3km of cat5 cables effectively and with ease. Furthermore, the Galaxy system makes transmission of high quality streaming video to multiple displays a viable option for business. Moreover, with Resolutions up to 1600x1200 over cable lengths of up to 1000m, with several kilometers of total capacity; Galaxy is a system with immense potential and capacity.
"Digital Signage" and "Retail Active Display" are concepts that include live displays for advertising and information fitted in any location from convenience-stores to airports.
The Galaxy system allows video distribution from a single computer to hundreds of monitors. The base units function as transmitters or repeaters for the image signals. Video equalisation and skew compensation, what equalises the video image between cable data pairs, allows video distribution for longer distances without lost of signals. Thanks to the modular design, it is a very flexible system allowing various different combinations of driving/splitting the video signal within your organisation. The max. distance between transmitter and receiver is up to 300m. A further distance can be reached by the use of a daisy chain card. The configuration shows the use of the Galaxy system for 8 monitors, e.g. in a shopping mall, 4 monitors with a max. distance of 60m and 4 monitors with a max. distance of 125m. The 2 transmitters are connected with a VGA cableto the computers video card. The system supports monitor integrated loudspeakers, is operating system independent and resistant against electric or magnetic interferences.

By distribution of VGA-signals over longer distances delay of single colours may occur, with shades as a consequence.
To help this problem, we recommend using Daxten's external 30ns skew delay line, which is placed between the remote unit and the monitor.
