Digital communication of Control Unit with the group of remote objects

Digital communication of Control Unit with the group of remote objects

A circuit on fig.1 * is used for the galvanic partition between the group of remote objects (Control Units, or units of reception/transmission of data). In the initial state In k = ,,1”, Out 1 =…Out n =,,1”. At any time the In 1 =,,0” (In n =,,0”), then Out k =,,0” and a data is passing by the data line. After this In k =,,0”, In 1 =,,1” (In n =,,1”) – the system is return in the initial state.

This circuit is used with the data line. Look more Communication of computer with remote objects.
