11.4 2-Wire Communication
Using the 2-wire communication reduces wiring cost in comparison to the 4-wire communications.
2-wire communications is available for network installations, in situations where other sensors are
only able to communicate via 2 wires (e.g. MI sensor). For setting the Interface Converter into the
2-wire communication mode, use the Network Communication Setup Software, found on the software
CD.
