1. An IR transmitting and receiving device having a signal communicator, comprising:
- an IR transmitter to output IR light;
an IR receiver used to receive the IR light from the IR transmitter and output electronic signals according to the IR light, wherein the IR receiver has an output;
an RF transmitter unit connected to the output of the IR receiver and comprising;
an analog to digital converter connected to the output of the IR receiver to convert the electronic signals from the output of the IR receiver to different digital signals;
an encoder connected to the analog to digital converter to encode the digital signals from the analog to digital converter to the encoded signals; and
an RF transmitter connected to the encoder to turn the encoded signals to radio signals; and
an RF receiver unit communicating with the RF transmitter unit comprising;
an RF receiver to receive the radio signals from the RF transmitter, wherein the RF receiver turns the radio signals into the encoded signals liked the encoded signals output from the encoder of the RF transmitter unit;
a decoder connected to the RF receiver to decode the encoded signals from the RF receiver to the different digital signals, each of which is presented to a strength of the corresponding electronic signal; and
a display device connected to the decoder to show the different digital signals;
whereby since a strength of the electronic signal output from the IR receiver is changed according to a strength of the IR light received by the IR receiver, the display shows different values according to the different digital signals corresponding to the electronic signals to an operator, wherein the operator adjusts angle of the IR light of the IR transmitter according to the values shown on the display to make the IR receiver receive a largest strength of the IR light.

Abstract
An IR transmitting and receiving device with a signal communicator has an RF transmitter unit connected to an IR receiver and an RF receiver communicating with the RF transmitter unit. The RF receiver is able to get the status of the signal at the IR receiver through the RF transmitter unit and then show the status on a display device. Therefore when a user sets the IR transmitting and receiving device, the user easily adjusts one position of the IR transmitter and the IR receiver, until the IR receiver received the max light strength from the IR transmitter.
