THE SERIAL DISTRIBUTION SYSTEM
In addition to functioning as a single distribution amplifier, the DA1902SX may act as a building block in the Altinex Serial Distribution System. The Serial Distribution System provides a manner of distributing a video signal to several displays in an application where the displays are typically spread a few distances apart. When numerous runs are made from the displays back to a single distribution amplifier at a centralized location, it is known as the “homerun approach”. As an alternative to the “homerun approach”, the Serial Distribution System uses the concept of a video bus to provide greater ease of installation and greater flexibility.
In the Serial Distribution System, the DA1904SX acts as an output module. Ordinarily, the source signal is connected to the input of a DA1902SX and this becomes the starting point for the bus. The outputs are then connected to the output modules, DA1904SX, which are usually located at each display site. The output modules provide a way in which the display can be fed while still maintaining a video bus output, which can be connected to several monitors. A maximum of 30 DA1904SX units and a total system length of 300 feet or less are recommended for optimum performance. See the Serial Distribution System on the following page for an example of the manner in which the Serial Distribution System can be applied.
