Using the Development Boards

After unpacking the development system, attach an antenna to the 
decoder board, install the 9V battery and turn on the power switch. 

The 

encoder and decoder are set at the factory to work straight out of the 
box. 

To create a new operational setup, follow these steps:

1.  On the decoder board, press and hold the LEARN button and then 

press the CREATE_KEY button to enter Create Key Mode. Release 
the LEARN button and press the CREATE_KEY button ten times to 
generate the KEY.

2.  Press the GET_KEY button on the back of the transmitter to activate 

the IR receiver. Hold the back of the transmitter close to the decoder 
boards's IR key transfer area until the MODE_IND LED turns on.

3.  Set Control Permissions by pressing the LEARN button on the decoder 

board.

4.  While the decoder's MODE_IND line is flashing, press each button on 

the transmitter that is to be granted recognition permission.

5.  After all the desired data lines have been transmitted, press the 

LEARN button again, or wait until the 15 second time-out occurs. The 
permissions are now saved in the decoder.

6.  Transmit with one or all of the authorized data lines to confirm that the 

learn process was successful.

Troubleshooting

If the boards fail to work out of the box, then try the following:

• 

Check the batteries to make sure they are not dead and that the 
antenna is connected.

• 

Make sure the baud rate switch is set correctly on the decoder board.

• 

Make sure the Encryption Key is set correctly. It is created by 
the decoder and must be sent to the encoder before they can 
communicate.

• 

Make sure that the Control Permissions are set correctly. If the 
transmitter has not been set to use a particular line, then when a 
button on the transmitter is pressed, the MODE_IND LED on the 
decoder board lights up, but the data line LED does not light up.

If all of these appear to be in order, then call +1 800 736 6677 or e-mail 
[email protected] for technical support.
