Use of the MTA service connector is limited to configuring the instrument (unit system, output
range, display, etc.). Both the HygroLab 2 and HygroLab 3 can also be configured via one of the
external digital ports.
Instrument configuration requires a PC with the HW4 software installed. Instructions for configuring
the HygroLab are provided in the software manual.
4.2 Baud rate compatibility requirements
Depending on the model, devices from ROTRONIC use one of the following Baud rates as the
factory default:
• 57600 bps: HygroLog NT data logger and docking stations
• 19200 bps: HygroPalm and HygroLab indicators, HygroFlex and M33 transmitters, HygroClip
Alarm programmable alarm card, HygroClip DI interface, HygroStat MB Thermo-Hygrostat
The factory default Baud rate of the HygroLab is compatible both with both the ROTRONIC HW4
and HW3 software and is the recommended Baud rate for the HygroLab.
IMPORTANT:
• All devices connected to a RS-485 multi-drop network (master and slaves) must use the
same Baud rate
• Models with the optional Ethernet (TCP/IP) interface: after using HW4 – Device Manager to
change the Baud rate, you should also change the configuration of the internal Ethernet
module to the new Baud rate (see separate HW4 manual).
Devices and internal Ethernet modules with mismatched Baud rate will not communicate together.
• The Baud rate configuration of a ROTRONIC device can be changed with the Device
Manager function (Digital Interface tab) available from within the HW4 software.
• The Baud rate of a Digi Module can be changed only from the module web interface. See
separate document IN-E-TCPIP-Conf_11 (available in PDF format).
4.3 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 models with an Ethernet (TCP/IP) interface should be
configured to be compatible with the local area network. Detailed instructions are provided
separately in document IN-E-TCPIP-Conf_11 (available in PDF format).
Models with an Ethernet (TCP/IP) interface 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:
