3.3.3 X3/EN & X4/AR Digital Inputs
The diagram below shows how to connect the X3/En & X4/AR Inputs to commonly used device.
Note: X3/En & X4/AR inputs have been internally pulled up to logical 3.3 VDC
Note: If the input voltage is between 5-24 VDC, or the input is not connected, the logic
state of that input is HIGH. If the input voltage is below 1VDC, the logic state of that input
is LOW.
