J2 and J4 (Molex, p/n 22-27-2041, 4A max) are provided for easy
connection of multiple devices, and are located at the left and
right sides. They carry the unregulated supply voltage and RS-485
bus signals.

J1 can be used to connect the supply voltage and the RS-485 bus
to the relay unit. These screw terminals are electrically identical to
the expansion connectors J2 and J4. In addition, a “reference
ground” and “Signal GND” pin is provided. Reference ground is
connected to the Signal ground of the Barionet R6 via a 100 Ohm
resistor and can be used for grounding applications. “Signal GND”
is the system ground of the R6 – which is NOT identical to the
supply “VSS” pin – and is used for measuring purposes only.
