Applicability:
This manual is valid for docking stations with firmware version 1.4 or higher, a nd with web server
version 1.0 or higher. Changes to the last digit of the version number reflect minor changes that
do not affect the manner in which the instrument should be operated.

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

2.3 Logical inputs (on / off)
Several models of docking station allow the HygroLog NT to process up to 2 logical inputs.
Typically this is used to monitor a relay contact, a door contact, etc.

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).
