ABSTRACT:
A control system for an actuator used to actuate a device. A receiver in the control system receives different transmitter identifiers from multiple transmitters. A central processor coupled to the receiver uses a received transmitter identifier as the address of a memory location. If the control system is set to a write mode when the transmitter identifier is received, a valid bit is set in the addressed memory location to indicate that the transmitter identifier is valid. If the control system is set to read mode when the transmitter identifier is received, the addressed memory location is examined to determine if a valid bit has been set. If the valid bit has been set, the central processor transmits a signal for actuating the device.
