8.1.1 Remote Switching Solutions
Using the Data Distribution Board LBB 3512/00 an interface facility is provided for the control of
external equipment such as loudspeaker group switching and other special switching facilities (FIG 8-
6).
Application 1.
Application 1, gives a typical solution when using the data distribution board in combination with an
interpreter desk. The interpreter desk includes an external message key, this key when pressed can
alert for example, some one in the secretariat via an LED indication panel or as a ‘speak-to-fast’
indication to the chairman.
Application 2.
Application 2, shows a typical example using the DCN system as a transparent control path using two
data distribution boards LBB 3512. Using this example a variety of switching solutions are possible- for
example, to switch lights on or off, or even to drive a motor that will open or close curtains as used
in large congress halls etc.
