Fronius IG Inverter Datalogger Easy Box
One Datalogger Box is required per DatCom system. The Datalogger coordinates data traffic and ensures that even large quantities of data are obtained and distributed flawlessly. It also stores the data collected from all FRONIUS IG inverters and any sensors in your weather station. Connection to a PC or an external modem allows you to monitor your PV system from anywhere in the world.
The simplest datalogging configuration for the Fronius IG inverter uses one (1) COM card, one (1) Datalogger Easy box, one (1) RS 485 / CAT 5 network cable (not supplied), two Termination plugs (supplied) and one null modem cable (not supplied).
The Com card plugs into the IG inverter, the CAT 5 cable is used to connect the COM card to the Datalogger Easy box, the Null modem cable connects the Datalogger Easy box to the computer. The Datalogger Easy box receives its power from the COM card via the CAT 5 cable (a separate power supply is not required). Note: the Datalogger Easy box does a power supply port that can be used for benchtesting the unit without the need for a IG inverter and COM card.
Both the CAT 5 cable and the Null modem cable are not supplied with the system due to the fact that there is no way of knowing how long the cables will need to be. And, these cables are standard, off-the-shelf, items available at any store carrying computer supplies.
