1 Quick-Start/Commissioning
Just a few steps are required to start up your W&T Web-Thermometer and to make it visible in your network.
Power-over-Ethernet
The Web-Thermometers are designed for use in PoE (Powerover-Ethernet) environments in accordance with IEEE802.3af.
Power is provided by the network infrastructure using the
RJ45 terminal. The devices support both phantom power
using data pairs as well as power feed using the unused wire
pairs s. Power Supply).
!
Use of the Web-Thermometer is also possible in networks
without PoE power supply. In this case simply use an
external power supply attached to the screw terminal as
described in the chapter Power Supply. No additional configurations or settings are necessary.
1.1 Connecting the sensor (#57713, #57714, #57715,
#57718, #57720)
8
W&T
Plug the sensor included in the scope of delivery into the
9-pin IO terminal on the unit.
Information for Web-Thermometer Air Quality, #57718:
!
The measuring of the VOC value begins after an initialization time of 15 minutes after powering on the device.
In this time a VOC value of 450ppm will be displayed.
1.2 Connecting the PT100/PT1000 sensor and output
configuration (#57616)
The output of the Web-Thermograph Relay is switched internally using a relay contact (normally open). The consumer
is connected to the screw terminals 1 and 2. The maximum
switchable DC or AC voltage is 39V, with a maximum current
flow of 300mA.
The PT100 or PT1000 temperature sensor is connected to
screw terminals 3, 4, 5 and 6, whereby the wires of the same
color must lie adjacent to each other.
9
W&T
The incoming line to the PT100 4-wire sensor may be of virtually any practical length.
Connecting a PT100 3-wire sensor:
When connecting a PT100 3-wire sensor the same-color wires
are connected to the terminals marked with the corresponding colors. A jumper to the remaining free terminal is required for the single wire.
Connecting a PT100 2-wire sensor:
When connecting a PT100 2-wire sensor, one wire is brought
to the red terminal and the other to the black terminal. Jumpers must be placed here to the free terminals.
10
W&T
1.3 Ethernet connection (#57713, #57714, #57715,
#57716, #57718, #57720)
The Web-Thermometer incorporates an IEEE802.3-compatible
network interface on a shielded RJ45 connector. The pin assignments correspond to an MDI port, so that the connection
to the hub or switch is accomplished using a 1:1 shielded
patch cable.

2 Online measurement storage inside the W&T Cloud
With the cloud service W&T offers a comprehensive solution
that enables the backup of data in online storage in addition
to the long-term documentation of temperature and humidity
measurement data in the internal data logger. The measurement data will be sent directly from the measuring point to
the cloud, and is available online.
2.1 Auto connect
The cloud functionality is enabled by default on delivery. If
the device receives its network parameters via DHCP, or you
allow the device Internet access by entering the network parameters, it immediately begins the transmission of the collected values in the cloud.
The measuring data is first not assigned to a user account
and will be stored in an enclosed part of the cloud until
further use.
2.2 Create a user account
To personalize the measurement data, first a user account for
the cloud access must be created. To do this, go to the cloud
homepage
http://cloud.wut.de
and click on „create user account“.
After entering your e-mail address and a password you will
get access to the cloud.
15
W&T
2.3 Assign data by 4-digit access code in the cloud
Log in with your user account to http://cloud.wut.de and
enter the access code included with the device. The collected
data are now associated with your account and are available
for you immediately.
Alternative:
2.4 Assign measured data via user account in the device
After you have created a cloud user account, open the configuration menu of your device and login as admin user. Navigate to the page
Communication Paths -> Cloud
and enter your user data for the cloud access. After clicking
on the button „Bind“ all measurement data of this device,
from this moment, is stored into your user account.
By clicking on the button „Unbind“ the allocation of the data
from this moment is separated and no further values will be
stored in your account.
Click again on „Bind“ and a new series of measurements is
created in the cloud for your user account that contains all
the unassigned values of the sensor.
!
For further information about the service of the Cloud
functions you find instructions on http://cloud. wut. de

3.1 Configuring network parameters with WuTility
WuTility is the central inventorying and management tool for
all W&T network devices. In addition to convenient assigning
of the IP parameters, WuTility also provides quick access to
device configurations, the ability to perform firmware updates, managing configuration profiles, etc.
WuTility can be directly installed from the included product
CD. Current versions are always available on our website at
http://www.wut.de. From there you can navigate using the
menu tree on the left side.
Downloads r Web-Graphr Software-Tools
After extracting the ZIP file you install WuTility by doubleclicking on the file wutility_***.msi. Start WuTility using
Start r All Programs r W&T Software Toolkit r WuTility
3.1.1 Applications and prerequisites
IP assignment using WuTility works regardless of the current
network parameters of the device and the computer used.
This means that even if the device does not have IP parameters consistent with the respective network, WuTility can be
used to overwrite them. Likewise, WuTility can be used to
assign any values not consistent with the network the PC is
located in.
• The PC and device must be located in the same physical
network. This means you cannot assign values through a
router.
• Any firewalls and network security packages installed on
the PC must allow communication between WuTility and
the device based on UDP broadcasts. If necessary these
must be correspondingly configured or temporarily turned
off.
17
W&T
• If the device does not have its factory default settings and
there is a system password assigned, this must be known
in order to make changes using WuTility.
Step 1: Start the assignment dialog
WuTility automatically searches the local network for connected W&T network devices and creates an inventory list. This
search process can be repeated manually as often as desired
by clicking on the Scan button:
Within the inventory list you can identify the desired device based on its MAC address. For initial installations its IP
address is 0.0.0.0.
Select the device and click on the IP address button:
18
W&T
Step 2: Assign the IP parameters
The Static option allows you to assign fixed basic parameters
while simultaneously disabling the DHCP protocol in the device. Enter the desired values for IP address, subnet mask and
gateway address in the corresponding entry fields. The DHCP
option enables DHCP protocol in the device, and operation
with a static IP address is no longer possible (see IP Assign-
ment using DHCP Protocol for detailed information).
Clicking on the Next button assigns the network parameters
to the device. After acknowledging the resulting message, all
the columns in the WuTility device list are filled in with information.
If necessary, the remaining configuration of the device is done
using Web-Based-Management. Click on the Browser button.
Browser:
Additional information can be found in the section Configuration Accesses for the Web-Thermometer.
19
W&T
3.2 Assigning the IP using DHCP protocol
DHCP protocol is activated by the factory default settings, so
that in network environments dynamic IP assignment is sufficient for connecting the device to the network. The following
parameters can be assigned using DHCP:
• IP address
• Subnet mask
• Gateway address
• DNS-Server
3.2.1 Manual activation of DHCP
To prevent unintended address assignments or address changes, DHCP protocol is automatically deactivated when using
all other methods for assigning the IP parameters. The following methods are then available for later activation of DHCP.
• Management-Tool WuTility
Select the desired device from the device list and click on
the IP Address button. In the following dialog check the
option DHCP and then click on Next.
• WBM configuration
In the menu branch Basic settings r Network r TCP/IP
Settings you can activate DHCP protocol.
1
A set static IP address is deleted after DHCP is
activated and the associated automatic reset. The device
automatically sets this to 0.0.0.0 and starts sending DHCP
requests.
20
W&T
3.2.2 System name
To support any automatic updating of the DNS system by
the DHCP server, the device identifies itself within the DHCP
protocol with its system name. The factory default setting
for this is WEBIO- followed by the last three places of the
Ethernet address. For example the factory set system name of
a device with the Ethernet address 00:c0:3d:01:02:03 is WE-
BIO-010203. The system name of the device can be changed
in the configuration. For additional information refer to the
section Menu: Basic Settings r Language/Infos.
3.2.3 Lease time
The lease time determined and transmitted by the DHCP
server specifies the Time-To-Live of the assigned IP address.
After half the lease time has expired, the device attempts to
extend the time for the assigned DHCP server and up update
the address. If this is not possible by the time the lease time
expires, for example because the DHCP server can no longer
be reached, the device deletes the IP address and starts a new
cyclical search for alternate DHCP servers for the purpose of
assigning a new IP address.
Because of the absent clock, the lease time associated with
the current IP address is no longer available after a reset.
After the restart therefore a corresponding update request is
issued with the original DHCP server. If the latter is not resolvable at this point in time, the device deletes the IP address
and starts a new cyclical search for alternate DHCP servers.
If DHCP is activated, the remaining lease time together with
the current IP address is displayed in the menu item device
Information using the format hh:mm:ss.
21
W&T
3.3 Assigning the IP using the ARP command
Requirements
This method can only be used if the device does not already
have an IP address, i.e. the entry is 0.0.0.0. To change an
IP address, use one of the other methods described in this
section or use the configuration menu over web based management. If the device has any other value, this access is
disabled.
When the factory setting is in effect as well as after a manual
changeover from static to DHCP, the method for assigning
the IP described in this section functions only after a delay of
approx. 2 minutes after a reset or after power-up.
This method does not work across networks, e.g. through
routers. This means the PC and device used for assigning
must be connected to the same physical network segment.
Only IP addresses whose Net-ID is identical to that of the assigning computer can be assigned.
1
To avoid unintended changes to the IP address, the
DHCP client of the Com-Server is automatically deactivated when configuring using a static ARP entry.
Step 1
Read off the Ethernet address of the device from the sticker
on the side of the housing.
58xxx [Typ]
EN=00c03d004a05
OK xxxxxx
Ethernet address
Insert a static entry into the ARP table of the computer using
the following command line:
arp -s [IP address] [Etherenet address]
22
W&T
E.g. under Windows:
arp -s 172.16.231.10 00-C0-3D-00-12-FF
E.g under UNIX/Linux:
arp -s 172.16.231.10 00:C0:3D:00:12:FF
1
The IP addresses must be without leading zeros in
all Windows environments. Otherwise the entry is incorrectly interpreted by the system and an incorrect IP address
is assigned to the device. In Windows Vista and newer the
prompt cmd.exe necessary for invoking the ARP command
must be started using Administrator rights.
Step 2
Use the following command line to ping the device with the
desired IP address:
ping 10.40.21.12
The device takes the IP address of the first network packet
sent to it as its own and saves it in non-volatile memory. The
ping requests of the PC are then replied.
It is not possible to configure the subnet mask and gateway
address using a static ARP entry. These need to be set in a
separate Telnet configuration session (see section Basic Confi-
guration of the device).
23
W&T
3.4 Assigning the IP using the serial port
After a device reset a time window of around 1-2 seconds is
available, during which you can assign a new IP address, subnet mask and gateway address by entering at least 3 „x“.
In contrast to other methods described above, this serial
method functions regardless of whether the device already
has an IP address, a password or not. The procedure can be
repeated as often as desired.
1
To avoid unintended changes to the IP address, the
DHCP client of the device is automatically deactivated
when configuring using the serial port.
Preparations/requirements
First connect the serial port A of the device to a computer. For
a standard PC or laptop, you will need a crossed RS232 cable
where only the pins 2,3, and 5 are connected.
Any serial terminal program can be used for assigning. The
following transmission parameters must be set regardless of
any other settings in the device:
9600 baud, no parity, 8 data bits, 1 Stop bit, no Handshake
Start the serial configuration mode
Reset the device by interrupting the power. While the device
is starting up, use the terminal program to send the letter x
at least three times. The device will then return the prompt
IPno.+<Enter>:.
Assigning the IP settings
Use the usual format (xxx.xxx.xxx.xxx) to enter the IP
address, and end the entry by pressing <Enter>. If the entry was accepted, the acknowledgement is the assigned IP
address. Otherwise you will get a FAIL message followed by
the last current IP address.
24
W&T
Together with the IP address, the subnet mask and gateway
address can also be assigned serially. The entry is separated
by commas and follows the IP address. Entering as shown in
the following example will assign IP address 172.17.231.99,
subnet mask 255.255.255.0 and gateway 172.17.231.52 to
the device.
Exampel: Assigning the IP address:
IP no.+<ENTER>: <- Web-Thermometer
172.17.231.99 -> Web-Thermometer
Example: Assigning IP address, Subnet mask and gateway
IP no.+<ENTER>: <- Web-Thermometer
172.17.231.99, 255.255.255.0,172.17.231.1 -> Web-Thermometer

4 Supply voltage
The Web-Thermometer can also be operated either using PoE
or from an external power supply.
The current draw can be found in the technical appendix.
4.1 Power over Ethernet
In PoE environments (Power-over-Ethernet, IEEE802.3af) power
is provided by the network infrastructure. The device supports both phantom power using data pairs 1/2 and 3/6 as
well as power feed using the unused wire pairs 4/5 and 7/8.
The Web-Thermometer is a device in PoE Power Class 1 (power consumption 0.44 to 3.84W).
4.2 External supply
As an alternative to PoE power supply the device can also be
powered by an external power supply connected to the screw
terminals on the underside of the housing. A half-wave rectifier makes the input reverse polarity protected. AC or DC
power may be used, whereby the following limit values must
be observed:
• AC: 18Vrms (- 10%) - 30Vrms (+10%)
• DC: 12V (-10%) - 48V (+10%)

8.5 Data storage
Configure at what time interval the measurement data should
be saved in the internal data logger and which sensors should
be included.
!
A change to these settings will clear the entire data
logger and the measurement recording will begin over
again.
In addition, you can download the contents of the data logger
as a CSV file for further processing. On this page you can also
clear the data logger.
8.6 Password
Set up optional password protection for access to the configuration.
You can set a password for an administrator-user and for an
operator-user.
The operator-user has no access rights to system settings for
the device, such as changing network parameters etc.
!
If you assign an administrator password, it must be
stored for IP address changes via WuTility or firmware
updates.

9 Communication paths
This device can communicate over various network protocols
and services. Here you configure all the parameters necessary
for this.
9.1 Web pages
This device has three preset pages which can be selected as
the start page.
The default homepage shows you the current values of the
individual sensors, which are updated cyclically.
The visualization page makes it possible to represent the
measurement values graphically.
The user page can be individually designed. To do this it can
37
W&T
be downloaded from the device, edited by you and again
uploaded.
To display the measurement values on the user.htm page you
can use the following tags in the source text, which are replaced with the corresponding values when the page is opened:
<w&t_tags=t1>
Shows the current temperature (°C) of the first temperature
sensor. When multiple sensors are used this index is numbered in sequence.
<w&t_tags=h1>
Shows the current relative humidity (%) for models 57713 and
57720.
<w&t_tags=ah>
Shows the current absolute humidity (g/m³) for models 57713
and 57720.
<w&t_tags=pa>
Shows the absolute air pressure (hPa) for model 57713.
<w&t_tags=pNN>
Shows the calculated air pressure (hPa) above sea level for
model 57713 (meteorlogical value).
<w&t_tags=al>
Shows the set altitude of the location of the device for model
57713. (m)
<w&t_tags=time>

Background color:
For values shown in tables you use use corresponding background colors depending on the sensor state:
<w&t_tag=bct>
Describes a background color (BGColor), which depends on
the alarm status of the temperature sensor. If a limit has been
38
W&T
violated, this color is red. Otherwise the tag does not describe
any explicit color. This tag is necessary for example for showing limit violations in red in the log table. (°C)
<w&t_tag=bch>
Background color for the relative humidity value
<w&t_tag=bcah>
Background color for the absolute humidity value
<w&t_tag=bcrc>
Background color for the current rate of change
<w&t_tags=sensorx>
Inserts the name of sensor x in the page.
<w&t_tags=device_name>
Inserts the assigned device name.
<w&t_tags=device_text>
Inserts the freely configurable, descriptive text for the device.
<w&t_tags=location>

14 Individual request of measurement values
14.1 Request via TCP/IP
It is possible to manually request the current measurement
values in CSV format (comma-separated data) through a sokket connection. This function is used for requesting individual
data without using the web interface.
To do this, send the following string to Port 80:
GET /Thermo.csv
This expression can also include additional parameters which
determine the contents:
start=ttmmjjjjThhmmss
Start-date and –time for the measurement data to be loaded
end=ttmmjjjjThhmmss
End-date and –time for the measurement data to be loaded
DTb=x&
Output interval, where x =
1 -> 15 Sek.
2 -> 30 Sek.
3 -> 1 Min.
4 -> 5 Min.
5 -> 15 Min.
6 -> 60 Min.
The expression must begin with “?” after the file name, where
the individual variables are separated by a “&”.
48
W&T
Example:
http://<ip-adresse>/thermo.csv?start=01012010T123000&end=30032010T200000&DTb=3&
The above expression generates a CSV file which contains
the measurement data from 01.01.2010, 12:30 p.m. until
03.30.2010, 8:00 p.m. in 1 minute intervals.
To request the individual current measurement value, send:
GET /Single1
for the 1st measuring channel
GET /Single2
for the 2nd measuring channel, etc.
To receive an output for all measuring channels, send:
GET /Single
without Index.
14.2 Requesting via UDP
Open a UDP connection to the IP address of the device or
to the Net-ID as a broadcast and Port 42279 (preset can be
changed).
Then send one of the above GET /Single expressions to the
device and the device will return the measurement values on
the port you are using.
i
When using multiple devices it may make sense to also
have the name and IP address of the device included
with broadcast messages. To do this, select “Enable GET
Header” under “Communication paths >> Socket access”.
49
W&T
14.3 Requesting via SNMP
The sensors can be queried directly using SNMP instructions.
The paths of the different model variations are:
#57713 Web-Thermo-Hygrobarometer:
1.3.6.1.4.1.5040.1.2.37....
#57714Web-Thermometer NTC:
1.3.6.1.4.1.5040.1.2.38....
#57715 Web-Thermometer Pt100/Pt1000:
1.3.6.1.4.1.5040.1.2.39....
#57716 Web-Thermometer Relay:
1.3.6.1.4.1.5040.1.2.40....
#57718 Web-Thermometer Air Quality:
1.3.6.1.4.1.5040.1.2.41....
#57720 Web-Thermo-Hygrometer
1.3.6.1.4.1.5040.1.2.42....
Access the sensors through the following path:
<IP-Adresse> 1.3.6.1.4.1.5040.1.2.X.1.3.1.1.1 = First channel
with a decimal point with comma separation
<IP-Adresse> 1.3.6.1.4.1.5040.1.2.X.1.4.1.1.1 = First channel
as three place integer value, without comma separation
<IP-Adresse> 1.3.6.1.4.1.5040.1.2.X.1.8.1.1.1 = First channel
with one decimal place with decimal point separation
50
W&T
The last index describes the channel number you are
querying.
!
For querying indicate the configured SNMP read or read/
write community.
An MIB for incorporating into management applications is
available for downloading on the datasheet page of the device
on the W&T homepage http://www.wut.de or in the device
itself at http://<ip-address>/mib.zip.
If you wish to change device settings via SNMP (IP address,
subnet mask, etc.) you must first start a session on the device
using your SNMP manager.
Entering the administrator password in the variable
wtWebGraphThermoBaroSessCntrlPassword
opens a session. By reading the variable
wtWebGraphThermoBaroSessCntrlConfigMode
you can check whether the session was successfully opened.
1 = Session opened, device is in configuration mode.
0 = Opening of the session failed. Check whether an incor-
rect password was entered.
After successfully opening the session, you can make any
desired configuration changes using the variables defined in
the private MIB.
After configuration is finished, close the session by writing
the variables
wtWebGraphThermoBaroSessCntrlLogout
wtWebGraphThermoBaroSessCntrlLogout =
51
W&T
1 All changes are saved
2 Quit without saving
If while a session is open no SNMP communication takes place
for a period of 5 minutes, the device itself will close the session and all changes are discarded.
1
Opening an SNMP session has priority over an HTTP
login. This means: A user with operator or administrator rights loses his browser access as soon as an
SNMP session is opened.
The description of the individual SNMP variables, OIDs etc.
can be found in the private MIB.

15 Firmware Update
The operating software for the Web-Thermometer is being
continuously improved. The following section describes the
procedure for uploading new firmware.
. Where is the latest firmware available?
. Firmware update under Windows
15.1 Where is the latest firmware available?
The most current firmware including the available update
tools and a revision list are published on our website at the
following address: http://www.wut.de
Please first write down the 5-digit model number located on
the Web-Thermometer before downloading. From the homepage you can then reach the product overview sorted by
article numbers, which takes you directly to the datasheet for
the device. Here you follow the link to the current version of
the firmware.
15.2 Firmware update over the network under Windows
Prerequisite is a PC running Windows XP/Vista/7/8/8.1/10
with a network connection and activated TCP/IP stack. The
update process requires two files which are as noted above
are available for downloading on the homepage at http://
www.wut.de:
· The executable WuTility tool for sending the firmware to the
Web-Thermometer
· The file with the new firmware for sending to the device.
No special preparation of the Web-Thermometer is necessary
for the firmware update.
53
W&T
The WuTility tool used for the update detects all WuT devices
located in your network and is for the most part self-explanatory. If any questions arise, please use the associated documentation or go to online help.
!
Do not intentionally interrupt the update process by disconnecting power or pressing the Reset button if one is
present. The Web-Thermometer will be inoperable after
an incomplete update
Never mix files with different version numbers in file names.
This will cause the device to become inoperable.
The Web-Thermometer automatically detects when the transfer of the new operating software is complete and then performs an automatic reset.
54
W&T
16 Hardware-Reset to factory defaults
A reset of the device to its factory defaults can be done via
hardware. For this purpose the device has a jumper on the
board. For normal operation this jumper must be out. To set
the factory defaults, proceed as follows:
• Power off the device and open the enclosure
• Close the jumper and reconnect the supply voltage. An
internal self-test will be performed during which messages
will be issued on serial port. The Fail messages in the lines
Port A: and TP Test: can be ignored.
• The self-test will be finished in approx. 20s, at which point
the factory defaults are active.
• Turn off the device, open the jumper and close up the
housing again.
1
Resetting the non-volatile memory results in a loss
of all the settings which are different from the factory
defaults, including the IP address, passwords and all measured values.
