can be determined at the receiver so theat any interference with other remote control system may be avoided.
Please refer to Figure 2.
The separator demarcates the custom code and the data code. It consists of a 4.2ms LOW pulse interval and
Custom Code may be selected by connection CS Input with Scan Output (KO0 to KO4). An example of a
D0 to D7 of the transmission code are the data code bits. When CS Input and the Scan Output (KO5 to
The leader code is located at the beginning of the transmission code and is made up of 8.4ms HIGH & 4.2ms
