LEADER CODE
The leader code is located at the beginning of the transmission code and is made up of 8.4ms HIGH & 4.2ms
LOW pulse and is modulated in 38KHz providing easy identification of the reception code head bit at the receiver.
CUSTOM CODE
Custom Code may be selected by connection CS Input with Scan Output (KO0 to KO4). An example of a
custom code selection is shown in the diagram below.

DATA CODE
D0 to D7 of the transmission code are the data code bits. When CS Input and the Scan Output (KO5 to
KO7) are connected, data bits—D5 to D7 becomes the system extended code bits. An example of the
Extended code Bits Selection is given in the diagram below:

2. SEPARATOR
The separator demarcates the custom code and the data code. It consists of a 4.2ms LOW pulse interval and
can be determined at the receiver so theat any interference with other remote control system may be avoided.
Please refer to Figure 2.
