This new port on the unit allows local connection to a PLC or any control and measurement device to the WAVEJOKER/P units in order to share data (meters, flows, ...), as well as the data from the WAVEJOKER/T tank units.
This port is added to the serial transparent port that allows the link between local units (PLC or any other) with the control center, using the WAVEJOKER as a radio-modem.
