1 Quick-Start/Commissioning
Just a few steps are required to start up your W&T Web-Ther-
mometer and to make it visible in your network.
Power-over-Ethernet
The Web-Thermometers are 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 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 congurations or settings
are necessary.

The output of the Web-Thermograph Relay is switched inter-
nally 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
ow 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.
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.

1.4 Ethernet connection
The Web-Thermometer incorporates an IEEE802.3-compatible
network interface on a shielded RJ45 connector.The pin assign-
ments correspond to an MDI port, so that the connection to the
hub or switch is accomplished using a 1:1 shielded patch cable.

Error-LED
The Error-LED shows errors of the device.
All LEDs on = Self-test error
The self-test performed after each start or reset of the device
could not be correctly nished.
This error can occur when you have prematurely broken off a
software update and the full operating software could not be
transferred. The device is no longer capable of being operated
in this condition. Repeat the software update over the network
(see Firmware update), and address the device using its
assigned IP address.
If this does not eliminate the error or should the error occur
irrespective of any prior software update, please return the unit
to W&T for service.
Speed Link/Activity
Speed (yellow)
OFF: Simultaneous illumination/ashing of the Link/Activity
LED means there is a link to a device at a rate of 10 MBit/s
(10BaseT).

LED means there is a link to a device at a rate of 100 MBit/s
(100BaseT).

device up again by interrupting supply voltage. If the condition
persists, please return the unit for inspection.
1If the Web-Thermometer has no IP address or Address 0.0.0.0, the on error and system error LEDs
remain on! The system error LED ashes 3x after a brief time. The
LEDs do not turn off until an IP address has been assigned.

2 Supply voltage
The Web-Thermometer can also be operated either using PoE
or from an external power supply.
1Connecting an external supply voltage and a PoE infra- structure at the same time is not permitted.
The current draw can be found in the technical appendix.
2.1 PoE-supply
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).
2.2 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 rectier
makes the input reverse polarity protected. AC or DC power
may be used, whereby the following limit values must be
observed:
•AC: 18Veff (- 10%) - 30Veff (+10%)
•DC: 12V (-10%) - 48V (+10%)
When powering with DC voltage polarity must be observed:

3.1 IP conguration 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 congurations, the ability to perform rmware updates,
managing conguration proles, 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 -> Web-Thermometer -> WuTility
After extracting the ZIP le you install WuTility by double-cli-
cking on the le e-5wwww-22-swww-***.exe. Start WuTility
using:
Start -> All Programs -> W&T Software Toolkit -> 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 rewalls 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 congured or temporarily turned
off.

19
Subject to error and alteration
• 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:

20
Step 2: Assign the IP parameters
The Static option allows you to assign xed 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 elds.
The DHCP option enables DHCP protocol in the device, and
operation with a static IP address is no longer possible (see IP
Assignment 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 lled in with information.
If necessary, the remaining conguration of the device is done
using Web-Based-Management. Click on the Browser button.
Additional information can be found in the section Cong. via
Web-Based Management.
