Abstract

A multi brand remote control transmitter includes a programmable memory for configuring the transmitter to transmit the IR control codes for a plurality of controllable devices of different manufacturers, each of which is identified by series of digits. Provision is made for recovering the series of digits from the programmed transmitter by a series of keyboard operations. The digits are read out by flashing an LED that corresponds to the controllable device.

Claims

1. A method of identifying the brand code programmed into a remote control transmitter, the transmitter including an LED for each of a plurality of different types of remotely controllable devices comprising:

entering the programming mode of the remote control transmitter;

initiating the read out of the brand code programmed into the remote control transmitter for a selected one of the types of different remotely controllable devices; and

flashing the corresponding one of the LEDs in groupings corresponding to the digits of the programmed brand code.

2. The method of claim 1, further comprising introducing a predetermined delay between the groupings.

3. The method of claim 2, further comprising flashing at a substantially constant rate for the digits 1 through 9 and flashing at a faster rate to indicate a zero.

4. The method of claim 1, wherein the initiating step further comprises:

simultaneously depressing a pair of selected keys on the remote control keyboard until one of the LEDs is illuminated;

performing a predetermined sequence of key operations to enter the programming mode; and

performing further key operations to select the LED corresponding to the desired remotely controllable device and to initiate brand code readout.

5. A programmable remote control transmitter including a plurality of keys comprising:

memory means for storing command codes for a plurality of remotely controllable devices, said memory means being programmable in a programming mode in response to the input of a series of brand identification code digits from corresponding ones of said keys;

a plurality of LEDs for identifying each of said plurality of different types of remotely controllable devices;

means for activating a corresponding one of said LEDs in a read out mode to read out the programmed brand identification code digits that have been programmed in said remote control transmitter for the selected one of said remotely controllable devices; and

said corresponding LED being flashed in groupings to identify the digits of said programmed brand identification code.

6. The control transmitter of claim 5, wherein selective operation of certain of said keys accesses said programming mode.

7. The control transmitter of claim 6, wherein said transmitter includes:

mode means for selecting a desired one of said remotely controllable devices, a corresponding one of said LEDs being illuminated to indicate the selected device.

8. The control transmitter of claim 7, wherein said corresponding LED is flashed at a substantially constant rate for the digits 1 through 9 and wherein said corresponding LED is flashed at a faster rate to indicate a zero.
