Figure 8. Mode A Bit “0” & “1” Waveform

MODE B

The diagram below gives us the transmission code format for Mode B. Under this mode, the custom codes are

not selected, therefore the transmission code only consists of the 6 bits data code followed by a sync. bit. Please

refer to the diagram below:

Figure 10. Mode B Bit “0” & “1” Waveform Diagram

Under Mode B, a maximum of 32 different instructions may be provided simply by connecting the inputs KI0 to

KI3 with the Scan Outputs KO0 to KO7, thereby constructing a 4x8 key matrix. When two or more keys are pressed

at the same time, the transmission output Dout is set to and the no transmission occurs. Please refer to the table

below.
