1 Quick-Start/Commissioning
Just a few steps are required to start up your W&T Web-ThermoHygrobarograph and to make it visible in your network.
1.1 Connecting the power supply 57612
Connect the AC adaptor provided to the terminal provided for the
12-24V AC/DC operating power. Polarity does not need to be
observed.
1.2 PoE power supply 57613
The Web-Thermo-Hygrobarograph PoE 57613 is designed for
use in PoE (Power-over-Ethernet) environments in accordance
with IEEE802.3af. Power is provided by the network
infrastructure using the RJ45 terminal. 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.
To enable power management for the supplying components,
the Web-Thermo-Hygrobarograph is identified as a Power Class
1 device with a power consumption of 0.44 to 3.84W.

W&T
Subject to errors and changes
As an alternative to PoE power supply, the Web-ThermoHygrobarograph PoE can also be powered by an external power
supply connected to the screw terminals on the underside of
the housing. DC voltage of any polarity as well as AC voltage
may be used.
!
Use of the model Web-Thermo-Hygrobarograph PoE 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 above. No additional
configurations or settings are necessary.
1.3 Connecting the temperature-humidity-air pressure

1.5 Assigning the IP address using „WuTility“
Once the hardware has been connected to the supply voltage
as described above, you must assign the IP address needed for
operation in a TCP/IP network. You can obtain the correct value
for this parameter from your system administrator.
!
The IP address must be unique throughout the network.
There are various ways of assigning the IP address. To make it
as convenient as possible, we have developed the „WuTility“
tool, which you can download from the WuT homepage at
http://www.wut.de. This procedure is described in the
following. A summary of the alternatives can be found in the
Appendix to this manual under 7.1.
Be sure that the PC you are using to assign the IP address is
located in the same sub-network as the module and that both
the PC and the module are connected to the network.
When it starts, WuTility automatically searches the local
network for connected W&T network devices and generates an
inventory list. This search process can be repeated manually as
often as desired by clicking the Scan button:
Select from the displayed list your Web-ThermoHygrobarograph based on the MAC address:
10
W&T
Click on the „IP address“ symbol:
In the resulting window enter the desired network parameters
for the device and confirm by clicking on „Continue“.
The DHCP client of the Web-Thermo-Hygrobarograph can be
activated in the following window.
Clicking on the Continue button assigns the network
parameters to the Web-Thermo-Hygrobarograph. All the
columns in the device list in WuTility are filled with information.
After clicking on the globe in the WuTility menu list your
standard browser is opened and you will see the start page for
the device.

1.6 IP assignment using DHCP protocol
Many networks use DHCY (Dynamic Host Configuration
Protocol) or its predecessor BOOTP described in the following
section for centralized, dynamic assignment of network
parameters. By default DHCP protocol is activated, so that in
network environments with dynamic IP assignment you only
need to connect the Web-Thermo-Hygrobarograph to the
network. The following parameters can be assigned using
DHCP:
• IP address
• Subnet mask
• Gateway address
• DNS server
• Lease time
1
To prevent undesired address assignment
or address changes, we recommend deactivating DHCP,
BOOTP and RARP unless these are expressly used in the
respective network environment. Web-Thermo-Hygrobarographs with incorrectly assigned IP address can be
conveniently found and reconfigured after the fact using the
scan function of the WuTility management tool.
1.6.1 Activating/deactivating DHCP
By default DHCP is activated. The following methods are
available for deactivating or later reactivating DHCP protocol.
• Management tool WuTility
Select the desired Web-Thermo-Hygrobarograph from the
device list and click on the IP address button. In the first
dialog window enter the new network parameters and then
click on Next.
12
W&T
In the following dialog window deactivate the options
BOOTP and DHCP. Click on Next to send the new
configuration data to the Web-Thermo-Hygrobarograph.
• Serial interface
As part of serial IP assignment you can specify the following
options for deactivating/activating the DHCP and BOOTP
protocols directly following the address string:
-0 r Deactivates DHCP and BOOTP
-1 r Activates BOOTP/RARP
-2 r Activates DHCP
A detailed description of this procedure can be found in the
section Alternative IP address assignment 7.1
• Web Based Management
In Config r Device r Basic Settings r Network you can
alternately activate or deactivate both the protocols. Detailed
information about this can be found in section Assigning the
basic network parameters 1.5.
1.6.2 System Name
To support any automated updating of the DNS system by the
DHCP server, the Web-Thermo-Hygrobarograph identifies itself
within the DHCP protocol with its system name. The factory
setting for this is WEBIO- followed by the last three places of
the Ethernet address. For example, the default system name of
a Web-Thermo-Hygrobarograph having Ethernet address
00:c0:3d:01:02:03 is WEBIO-010203. The system name of the
Web-Thermo-Hygrobarograph can be changed using Web Based
Management.

W&T
Subject to errors and changes
1.6.3 Lease time
The lease time determined and sent by the DHCP server
specifies how long the IP address will remain in use. After half
the lease time has expired the Web-Thermo-Hygrobarograph
attempts to extend the time for the assigning DHCP server and
to 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 Web-Thermo-Hygrobarograph deletes
the IP address and starts a cyclical search for alternative DHCP
servers in order to assign a new IP address.
Because the clock is missing, the lease time associated with the
current IP address is no longer available after a reset. Therefore,
after the restart an update query is generated for the original
DHCP server. If it is not available at this time, the Web-ThermoHygrobarograph deletes the IP address and starts a cyclical
search for alternative DHCP servers.
If DHCP is activated, the remaining lease time together with the
current IP address is shown in seconds in the menu branch
Home r Doc r Property.
1
If after the assigned lease time has expired the DHCP
server cannot be reached, the Web-Thermo-Hygrobarograph deletes its IP address. All existing TCP/UDP connections
between the Web-Thermograph and other network clients are
closed. To prevent disturbances of this kind, we recommend
setting the lease time in the DHCP server to infinite.
14
W&T
1.6.4 Reserved IP addresses
The Web-Thermo-Hygrobarograph provides services which can
make use of other clients in the network as needed. To open a
connection they of course need the current IP address of the
Web-Thermo-Hygrobarograph, so that in these applications it
makes sense to reserve a particular IP address for the Web-Thermo-Hygrobarograph on the DHCP server. As a rule this is done
by joining the IP address to the worldwide unique Ethernet
address of the device, which can be found on the sticker on
the housing.
1.6.5 Dynamic IP addresses
Fully dynamic IP address assignment, in which the Web-Thermo-Hygrobarograph gets a different IP address after each
restart or after the lease time has expired, is only useful in
network environments with automatic cross-connection
between the DHCP and DNS services. This means when a new IP
address is assigned to the Web-Thermo-Hygrobarograph, the
DHCP server then automatically updates the DNS system as well.
The new address is assigned to the respective domain name.
For detailed information about your network environment,
consult your system administrator if in doubt.
Dynamic, changing IP addresses can also be used for time
server queries, sending of e-mails or other client applications
in which the device itself searches for active connection to
server services located in the network.
