1 Overview
Docking station model DS-U4WEB allows connection of the HygroLog NT data logger to an
Ethernet local area network (TCP/IP) and communication with a PC with the ROTRONIC HW4
software installed. This docking station has 4 probe inputs and 2 digital inputs that can be used to
monitor a contact.
The DS-U4WEB also features a Web Server that can be accessed directly from a standard web
browser just like any web site by typing the IP address of the docking station. This Web Server
can display current measurement data, schedule recording by the data logger, download log files
and configure both the data logger and docking station from any PC, even a PC on which the
HW4 software has not been installed. The Web Server can also generate a number of XML
pages which allow data integration into other applications.

2.2 Probe inputs
Depending on the model of docking station, the signals from up to 4 additional probes can be
processed by the HygroLog NT. These probes can be either HygroClip digital probes or analog
probes (including pres sur e pr obes) . An y input used tog ether with an ana lo g probe s houl d be
configured with the ROTRONIC HW4 software. Detailed configuration instructions are provided in
document IN-E-DS-Aconf_10.doc.
HygroClip probes
An adapter cable is required to connect a probe to inputs 4, 5, 7 and 7 of the docking station. Use
cable MOK-02-B5 (or similar) for probes with a 5-pi n DAT-05 connector. Use cable T7-03-B5 (or
similar) for probes with a 7-pin T7 connector.
Analog and pressure probes
The probe inputs of a docking station can be configured to accept an analog probe. Analog
probes cannot be used with the probe inputs of the HygroLog NT and these inputs are designed
for use with the HygroClip probes only. An analog probe can be used to measure with the
HygroLog NT a parameter other than humidity or temperature. For example, an analog pressure
probe may used to provide the value of barometric pressure required for the calculation of
parameters such as the wet bulb temperature, mixing ratio or enthalpy.
The following requirements and restrictions apply to analog probes:
● ROTRONIC analog humidity-temperature probes with the standard temperature output signal of
– 0.5…2.0 V = -50…200°C: because the HygroLog NT cannot read a negative voltage signal,
temperature measurement is generally limited to values above freezing.
● Third-party analog probes: single channel probes (one signal), voltage output signal within the
range of 0 to 2.5 VDC, supply voltage: 7.6…9 VDC (direct from the HygroLog NT battery) or 12
VDC when using an AC adapter, maximum current consumption: 10 mA.
Docking station model DS-U4-4-20 accepts up to four 3-wire single channel analog probes with
a 4-20 mA current output signal. Each probe input uses an internal 150 Ohm resistor to convert
4…20 mA to 600…3000 mV (nominal). The HW4 software allows a 2-point adjustment of the
mA to mV conversion to compensate for the tolerance on the 150 Ohm resistor (use Device
Manager in HW4). The probes are powered by the docking station (supply voltage: 7.6…9
VDC (direct from HygroLog NT battery) or 12 VDC when using an AC adapter, maximum
current draw: 10 mA / probe). It is also possible to use a 2-wire single channel probe but in that
case only one probe can be connected to the docking station (use any of the two probe inputs).
Connecting two 2-wire probes at the same time would create a current loop and result in
erroneous measurements.
● Resolution is limited by the 10-bit A/D converter used for the analog inputs. This converter
provides a theoretical maximum of 1024 counts for an input voltage span of 2.5 VDC. In theory,
this gives a resolution of 2.5 / 1024 = 0.00244 V. In practice, it is not possible to get 100% of
the counts from an A/D converter and the actual resolution should be about 0.0027 V (typical).
For example, if a probe with a temperature signal of 0...1V = 0…100°C is being used, the
signal resolution will be about 100 x 1 x 0.0027 = 0.27°C

2.5 Operating limits
The docking station operating limits are the same as for the HygroLog NT data logger:
HygroLog NT without display:
● -10…50°C with the factory supplied alkaline batt ery
● -30…70°C with a lithium battery or an external AC adapter
HygroLog NT with display:
● -10…50°C with the factory supplied alkaline battery
● -10…60°C with a lithium battery or an external AC adapter
The HygroClip probes have generally wider operating limits (see individual probe specifications).

4 ROTRONIC device configuration certificate
ROTRONIC docking stations with an Ethernet interface (both wired and wireless) are shipped
with a Device Configuration Certificate that provides information about the factory configuration
settings, in particular the TCP/IP settings. See example below:
Setting Value
Note: the Baud rate setting of the DS-U4WEB internal Ethernet module cannot be changed and
is always 57600 bps. Consequently, any HygroLog NT used with this docking station should also
be set to a Baud rate of 57600 bps to enable communication between the logger and docking
station.

5 Baud rate compatibility requirements
The default factory Baud rate for both the HygroLog NT and docking stations with Ethernet
interface is 57600 bps.
Devices with mismatched Baud ra te will not communicate together. A Baud rate mismatch
can become an issue when an existing da ta log ger is u sed wit h a new docking station.
Prior to using an existing data logger with a new docking station, you should verify that the Baud
rate of the data logger is set to 57600 bps. On a data logger with display and keypad, the Ba ud
rate can be displayed by using the keypad: MENU > Instrument.
The Baud rate settings of the HygroLog NT can only be changed with the Device Manager
function (Digital Interface tab) available from within the HW4 software. Depending on the
situation, you may have to use a docking station with either an RS-232 (COM port) or USB
interface to connect the logger to the HW4 PC. Communication between the HygroLog NT and a
docking station with either RS-232 or USB interface is not affected by the baud rate of the data
logger.
6 Configuration of the internal Ethernet module
• Place a HygroLog NT on the docking station. Use an AC adapter to power both the data
logger and docking station.
IMPORTANT: Prior to using a new docking station with a previously configured data logger,
you should verify the Baud rate used by the data logger and, if necessary, use HW4 Device
Manager to change the Baud rate of the data logger to the factory standard of 57600 bps.
• Prior to connecting the docking station to the local area network, please read the Dev ice
Configuration Certificate supplied with the docking station as well as document
IN-E-TCPIP-Conf_11. This document provides detailed instruction for configuring the internal
Ethernet (TCP/IP) module of the docking station to make it compatible wit h your local area
network.
Notes:
• The utility Finder.exe is provided on the HW4 software CD. This utility can be used to
discover the internal Ethernet module of the DS-U4WEB docking station and changing its
TCP/IP settings. To start Finder.exe, double click on the file with the mouse. The following
password is required: Netsilicon
• The internal Ethernet module of the DS-U4WEB is not compatible with the Digi Device
Discovery utility mentioned in document IN-E-TCPIP-Conf_11
• Configuration of the TCP/IP settings can also be done with the docking station Web Server
(provided that the TCP/IP settings of the DS-U4WEB are compatible with the LAN to which
the docking station is attached and the IP address of the DS-U4WEB is known).

7 Other configuration settings
Either the HW4 software or the Web Server can be used to configure both the HygroLog NT data
logger and docking station. Unlike HW4, the Web Server does not generate an authent icate d
configuration protocol. For this reason, using HW4 should be the preferred configuration method.
With the exception of the TCP/IP settings and other settings of the docking station internal
Ethernet module, all configuration data is retained in the HygroLog NT non-volatile memory. In
particular, no input configuration data is retained in the docking station proper. Therefore, it is
important to observe the following:
• Prior to configuring the data logger and docking station with the HW4 software, we strongly
recommend enabling HW4 to generate and save protocols (see below). After using Device
Manager in HW4 to configure the data logger and docking station, print the configuration
protocol for your records. This protocol includes information that will eventually be usef ul
such as serial number and firmware version of the data logger, serial number and firmware
version of the docking station as well as detailed configuration settings (logger and docking
station).
• Search for the data logger with HW4 and use Device Manager to configure both the data
logger and any available probe or logical input of the docking station as required by the
intended application.

8.2 Additional information
• The Web Server graph data is lost when power is turned off.
• When the IP address of the data logger is accesses via Internet, be cautious when
synchronizing the data logger time and date with your PC since you may not be in the same
time zone as the data logger.
• After synchronizing the data logger time and date with the PC, go to Web Server Settings and
click on “Apply”. This erases all data from the docking station volatile memory and prevents
potential conflict between the old and new time.
• Except for the log file header, HW4 is required to read the data from any downloaded log file
in binary (LOG) format.
• HW4 is required to view the data from any downloaded log file in graphic form.
• The data logger cannot be interrogated or writt en to du ring a file do wnlo ad. Me as u rement
data displayed by the Web Server is not updated.
• Direct connection via TCP Port 2101: to maintain compatibility with HW4, connectivity with
the data logger is possible using the TCP Protocol. This function cannot be disabled or
password protected.
• RS-485 network: not supported, with or withou t HW4.
