Digital Output Holding Function

A yellow mini jumper is added to the PCB, the major function of which is to hold the digital output value at its last status so that it won't be erased when the RESET button of your system is pressed or your system software going into reset.

To enble your Digital Output Holding Funciton, you must first set the yellow mini jumper on. When the Digital Output Holding Function is enabled, the digital output value of ADAM-5060D will first be cleared during system power-on. When the RESET button is pressed or when a system software reset occurs, its digital output value will be held at the last value.

To disable your Digital Output Holding Funciton, you must set the mini jumper off. When the jumper is off, it's functions just like an ADAM-5056.
