ADAM-4000/5000 System Grounding Installation
The shielding material of the wires should only be grounded on
one end as illustrated in the following diagram. This is to avoid
ground loop.

Since shielded twisted-pair has been adopted for signal wires, only
DATA+ and DATA- of ADAM-5000 system should be connected.
And the shielding materials should be treated in the same manner
as with AI and AO signal wires, i.e. it should be connected to
Ground on only one end through the COM port on computer or on
ADAM-5000 system such as illustrated in the following diagram:
