Configure the multiplexer

Use the S0, S1, S2 and S3 dropdowns to specify the board pins used. Set the Data dropdown to the board pin connected to the SIG pin on the breakout board.

Specify the size of the multiplexer using the Type dropdown. Use 8-bit multiplexer for 74HC4051 chips and 16-bit multiplexer for 74HC4067 chips.

Provide a meaningful name for the multiplexer in the Name field. This name is shown in the input configuration screens when assigning the multiplexer to a flight simulator input.

Tip

When connecting additional multiplexers to the same board, they can share the S0–S3 pins. Each multiplexer must use a dedicated Data pin.
