9. Ethernet local area network
ROTRONIC devices with an Ethernet (TCP/IP) interface presently use an internal module
manufactured by Digi International (Digi Connect ME for a wired connection, Digi Connect WI-ME
for a wireless connection). Both types of module feature a web interface that is used to configure
the module.
IMPORTANT: The TCP/IP settings of both the HygroClip DI-4 and DI-4-WL should be configured
to be compatible with the local area network. Detailed instructions are provided separately in
document IN-E-TCPIP-Conf_10.doc (also available in PDF format).
Both the HygroClip DI-4 and DI-4-WL are shipped with a Device Configuration Certificate that
provides information about the factory configuration settings of both the Ethernet module and
device. See example below:

10. RS-485 multi-drop network
All models of HygroClip DI feature a RS-485 connector. When the number of available PC ports
is limited, this connector can be used to connect together up to 64 HygroClip DI (or other devices)
in a multi-dropped arrangement. In principle, an unlimited number of such networks can be
monitored with the HW4 software, but each RS-485 multi-drop network is limited to 64 devices.
The HygroClip DI can be used either as a slave or a master, without special configuration. The
master is automatically the device that is directly connected to the PC or LAN by means of a USB
port or TCP/IP port.
RS-485 Address: the RS-485 address is used to identify the individual devices that are
connected to a RS-485 multi-drop and must be unique to each device. This address is part of the
HygroClip DI communications protocol. The factory default for the RS-485 address is 00. In
general, this address should not be changed manually (see note below). As far as HW4 is
concerned, all masters can share the same RS-485 address. When the HW4 command “Search
