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.
