I am installing an EPM II, one of the more recent Indoor/Outdor RFID readers, and I am not sure which wires need to be connected to what. I know in the older ones, the station wires go in 1 and 2, and so on. On this one, the wires are attached to the circuit board and I need to know which is the common and NC connectors. Also, does the EPM II have a jumper to switch it from NO to NC? Any help would be greatly appreciated. Thanks!
