1 Quick-Start/Commissioning

Just a few steps are required to start up your W&T Web-Thermo-

Hygrobarograph 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.

Subject to errors and changes

As an alternative to PoE power supply, the Web-Thermo-

Hygrobarograph 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

sensor

Plug the sensor included in the scope of delivery into the 9-pin

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-Thermo-

Hygrobarograph 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

1To 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-Hygrobaro-

graphs 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.

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-Thermo-

Hygrobarograph 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.

1If after the assigned lease time has expired the DHCP

server cannot be reached, the Web-Thermo-Hygrobaro-

graph 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-Ther-

mo-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-Ther-

mo-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.
