Has anyone who might be using Dupline products built their own Dupline to serial port interface?
The data has a 8 millisecond synch pulses and up to 128 pulses every millisecond there after depending on how many channels are bring used. then it repeats. No other layers of data so far as I have read. Carlo Gavazzi refers to this data stream as Field-/Installationbus
Its serial in nature as only two wires are used, on for data and one for common. The pulses appear to be negative going between 8.2 - 2.2 volts with the active sensor pulling that low voltage to 0.7 volts on a per pulse basis. so if one channel is active only one pulse of that available number of pulses with be going to 0.7 volts.
I have two systems with over 2000 water level sensors attached.I would like to be able to monitor for an intermittent water sensor using a PC that would store when the sensor was active.
I am aware Dupline does make some interface products, but none seem to fit my needs or are configured that I can utilize them.
It never hurts to ask if somebody here has crossed this bridge.
Thanks
