The VDO terminals have the same digital output functions (1 to 41) as the DO terminals do. The VDO can be used together with
VDIx to implement some simple logic control.

Here use the AI terminals as DI. When the AI input voltage is higher than 7 V, the AI is in the high level state. When the AI input
voltage is lower than 3 V, the AI is in the low level state. The AI is in the hysteresis state between 3 V and 7 V.
