Sentera advises to use Shielded Twisted Pair (STP) or Unshielded Twisted Pair (UTP) cable to connect Sentera devices via Modbus RTU.
The wires should have the following characteristics: - Characteristic impedance: 120 Ω ±10% - Specific resistance depending on network length
Modbus RTU has a line topology - the Modbus RTU should be connected from device to device and branches should be minimised.
