I had in the profilux 3 a second pH card and another RS-232 card to connect the LB Mitras.

I installed the two cards in profilux 4, recognizes them perfectly.

First problem: the pH card goes backwards, when calibrated in the liquid pH 4 starts to raise the pH value up to more than 8. When the CO2 is turned on it also raises the pH value.

Second problem: LB Miter does not work via RS232, the lighting channels do not apply.

Thanks
