Differential Input Signals
Signals of this type are required to have connections to plus and minus. Analog ground is a
function of the input signal and is connected as required. Refer to the figure below for this type
of connection.

4.2.4
Current Input Signals
Signals of this type are required to be connected: plus to plus; minus to I. In addition the minus
pole must be connected externally to minus of the CON2 connector. Refer to the figure below
for this type of connection.
