Abstract
When the connection of a cable to a control interface is confirmed, and thereafter a write command is received, a data write process is executed to renew contents of a conversion table stored in a memory based on link data attached to the write command. Furthermore, when a read command is received, a data read process is executed to retrieve the contents of the conversion table stored in the memory and thereafter to transmit the retrieved data to an external device through the control interface. Then, when disconnection of the cable is detected, the processes, each of which is executed according to the corresponding command transmitted from the external device, are bypassed.
Claims6
A portable transmitter for remotely operating a plurality of vehicular devices, each of which provides a corresponding one of a plurality of functions, the portable transmitter comprising:
- a plurality of switches, each of which is linked with a corresponding one of the functions;
- an operation command generating means for generating an operation command that causes a corresponding one of the vehicular devices to provide a selected one of the functions, which is selected upon operation of a corresponding one of the switches;
- a transmitting means for performing wireless transmission of the operation command upon reception of the operation command from the operation command generating means;
- a storage means for storing link data, which includes a plurality of links, wherein each link connects between a corresponding one the switches and a corresponding one of the functions;
- an interface means for receiving an external command outputted from an external device;
- and
- a write control means for writing the link data in the storage means based on the external command received through the interface means, wherein the operation command generating means generates the operation command based on the link data stored in the storage means.
