Antenna plug
For screwing on the WLAN antenna
Modbus termination switch (for Modbus RTU)
Internal bus termination with 120-ohm resistance (yes/no)
Switch in "on" position: Termination resistance of 120 Ohm active
Switch in "off" position: No termination resistance active
IMPORTANT! The termination resistance must be active for the first and last device
in an RS-485 bus.
For switching between master and slave mode within a Fronius Solar Net ring
IMPORTANT! All LEDs on the Fronius Datamanager 2.0 plug-in card are off in
slave mode.
