0-20mA Interface.
A typical circuit diagram is shown below.
When the sensor need a power source to convert its sensing el-
ement to current, the coupling is referred to as a“passive” type
connection. A typical passive connection diagram is shown
below.
When the sensor source its own power in the convertion proc-
ess, the coupling is referred to as an“active”connection. A typi-
cal active connection diagram is shown below.

0-20mA Calibration
It will be better to install the local unit, “UNIT-X”, on the current
loop transmitting side and the remote unit,“UNIT-Y”, on the
receiving side. Only the remote side will be congurable.
Set up the units and let them run for a short while.
Check if the output of the receiving unit, on the remote
side, correspond to the desired output.
If there is an error with the output, calibration is needed.
Connect a PC and the same network as the remote unit.
Open hyper terminal and give the connection some name.
In the “Connect to” window select the TCP/IP (Winsock) in
the “Connect using” eld.
In the “host adress” box, enter the remote IP adress and in
the “port number” box, enter “10001”.
When the two netshield units are operational, hyper termi-
nal will not make a connection and will give an “unable to
connect” error.
Switch o the transmitting unit (UNIT-X) and wait for one
(1) minute.
Click on the call button. There should not be any er-
rors after one (1) minute. When two minutes has lapst and
no new connection is made, the unit will default to zero
mA.
When a connection has been established, enter‘Ctrl’+
‘Shift’ + ‘6’ and a menu will appear with the commands for
the calibration.
When done with the calibration enter the‘s’ket to save and
exit.
Disconnect the call from on hyper terminal.
Connect the local unit (UNIT-X).
