DISTRIBUTION AMPLIFIERS
THE SERIAL DISTRIBUTION SYSTEM
In addition to acting as a single distribution amplifier, the DA1904SX may act as a building block in the Altinex Serial Distribution System. The Serial Distribution system provides a method 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 home run approach. The Serial Distribution System, an alternative to the home run approach, 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.

Typically, 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 and provides a way in which the display can be fed while still maintaining a video bus output to several monitors. A maximum of 30 DA1904SX units and a total system length of no more than 300 hundred feet are recommended for optimum performance. See the Serial Distribution System diagram on the following page for an example of the way in which the Serial Distribution System can be applied.
