With RFID3 API it's easy to trigger the read inventory when GPI port 'n' changes state to true or false - one just specify the port number and state to wait for, for example triggerInfo.StartTrigger.GPI.PortNumber =1; triggerInfo.StartTrigger.GPI.GPIEvent = true;

There are two GPI ports on FX7400 and customer wants to start inventory when either port 1 or port 2 becomes true. Is it possible and how? Thanks, Valery
