I have a customer that wants to control their access control system (Rosslare ACC225) with an RTI system. More specifically they would like to have the ability to momentarily unlock 1 of 5 doors temporarily and 2 of those 5 doors need to be unlocked indefinitely until they decide to lock them back. The button that controls the 3 that will be temporarily unlocked needs to keep them unlocked the duration of the button press however long that is. I would prefer to control this via rs232 or via ip control but have been unable to find any codes and/or drivers for either of them. Does anyone have any ideas on how I should go about integrating this?

Thanks!
