Going fully digital is often the better strategy: compared to wiring the analog output signals to a central location, using the digital output of the M3 transmitter provides the following benefits:

► Better accuracy because no signal conversion is required
► Wiring is easier to implement
► Data transmission over long distances is more reliable
► A large number of transmitters can be put on the same network.

Example: LAN (TCP/IP) and RS-485 network

Up to 63 M3 transmitters and one HygroClip DI-4 interface can be connected together in an RS-485 multi-drop network (for details, click on the picture below). The DI-4 interface is connected to the same LAN as the PC. Depending on the number of free ports available on the LAN, up to 253 DI-4 interfaces may be used. One or several local area networks as well as the Internet can be used to the purpose of centralizing data from remote locations.

The ROTRONIC HW4 software displays the data as a table of as a graph and provides additional functions such as data logging, alarms, etc.
