SYSTEM AND METHOD FOR REMOTE ACTIVATION USING A TRANSMITTER SWITCH ARRAY
First Claim
1. A remote control unit for activation of one or more vehicle functions, the remote control unit comprising:
- a user interface for selecting a command associated with the one or more vehicle functions;
a controller for processing the selected command, the controller having a plurality of input ports; and
a switch array having a plurality of switches corresponding to the one or more vehicle functions, the plurality of switches including a first set and a second set, each of the first set of switches connected between a fixed voltage and one of the plurality of input ports and each of the second set of switches connected between two of the plurality of input ports;
wherein at least one of the plurality of input ports connected to the second set of switches is convertible to an output port for sending a data message upon actuation of at least one of the plurality of switches for determining the selected command.

Abstract
A system and method for remote activation of a device includes, in one embodiment, a user interface for selecting a command associated with the one or more vehicle functions, a controller for processing the selected command, the controller having a plurality of input ports, and a switch array including a plurality of switches corresponding to the one or more vehicle functions. The plurality of switches can be divided into a first set and a second set with the first set of switches being connected across a fixed voltage and a controller input port and the second set of switches being connected across multiple controller input ports. The at least one of the controller input ports connecting the second set of switches may be temporarily configurable to an output port for determining which of the plurality of switches has been actuated.
