The blink modifier alternates the output value between the specified Alternate value (typically 0) when the original value is 0 and 1 when the original value is 1.

The Alternate value field specifies what value should be sent when the blink sequence is in the 0 state.

The Blink sequence specifies how many milliseconds the value should be On followed by how many milliseconds the value should be Off. Multiple sequences can be added using the Add blink interval button to create complex blink patterns.
