Jumper top position provides 0Vdc or 0mA start point for Out(1), Out(2)
(0-20mA or 0-10V).
Jumper bottom position provides 2Vdc or 4mA start point for Out(1), Out(2)
(4-20mA or 2-10V).

Option - Network Adapter for Connection to RS-485-Network
The network adapter can be used to connect the sensor to a RS-485-network. The
adapter is a small printed circuit board which can be used with all sensors with the
housings large enough. The green LED flashes every time the adapter answers calls
from the network master.
The adapter should be mounted perpendicular to the main PCB. The adapter
should be put on the UART connector with all five pins connected. All five pins
of the UART must be connected. For aSENSE the adapter should be mounted with
the RS-485 terminal facing the other terminals and the LED facing the display.
