Prevention of Mutual Interference

Radiation from the transmitter and receiver is in the form of divergent cones with an angle of 4˚. The
diameter of the radiated light beam thus increases with increasing distance and irradiates the
receiver accordingly. Mutual interference and hence functional disturbance can result if a second
receiver is positioned within this range.
Two differing transmission channels can be set by means of the DIP switch S2 in order to prevent
this. The units can be mounted in opposite directions or be separated by appropriate shielding.
