I just bought a Expansion card that named PL-0871 wich is 1 bnc input for ph or redox and one input for level.
The redox probe shows the right values, but when i try to setup ATO with one sensor i dont seems that the card or computer detects the sensor.
How can i control if the sensor i recognised by the computer at all ?
i just detected that if i connect an optical sensor into the expansioncard the computer sees it, but if i connect mechanical floatsensor it wont work ?
