Glossary

ANALOGUE	A command that can vary between the minimum and maximum value of a voltage or current.
RECEIVING UNIT	A device which, when connected to the machine to be controlled, decodes the digital data sequence and transforms it into electrical impulses which the machine needs in order to carry out the command selected by the operator on the portable transmitting unit
TRANSMITTING UNIT	A portable unit which communicates, to the receiving unit, the sequence of digital data that forms the command selected by the operator using the transmitting unit command devices (pushbuttons, selectors, joysticks).
APPLICATION	Sector where the radio remote control is used.
ACTUATOR	Electromechanical device which transforms a mechanical movement into an electric signal.
COMMAND	An individual instruction which must be given to the machine in order to carry out a single movement or task.
FUNCTION	A set of commands which carry out the same movement in its different directions or shifts.
UNSTABLE	A command which returns to its rest position.
RANGE	Maximum transmitting distance possible between the transmitting unit and its receiving unit.
PROPORTIONAL	A command that can vary between a minimum and a maximum voltage or current value according to the movement of an actuator.
