Shielding
Always shield a Modbus over Serial Line Cable. At one end of each cable its shield must be
connected to protective ground. If a connector is used at this end, the shell of the connector
is connected to the shield of the cable.
Note
Cable specifications
A RS 485-Modbus must use a balanced pair (for D0-D1) and a third wire (for the Common).
For the balanced pairs used in an RS 485-system, a Characteristic Impedance with a value
between 100 and 120 Ohms must be used.
