1.1 Ethernet connection
The network connection is provided in the form of an IEEE-8023-compatible terminal on a shielded RSJ45 plug located on the
front of the unit. Here the Web-IO 8x Thermometer can be connected to a hub or switch. The pin configuration corresponds
to a standard MDI interface (AT&T258), so that a 1:1 cable with
a length of maximum 100 meters can be used.
10BaseT, 10MBit/s or autosensing 100BaseT, 100/10MBit/s are
supported:
Please note that all plugs must be connected and disconnected only with the terminal devices are turned off.
!
Be sure that the network cable for the Web-IO does not
exceed a maximum permissible length of 100m.

After a reset the device is restored to its factory default set-
tings. Make your network settings again as necessary. For
more information on menu guided configuration, see section 3. and following.
Power-LED + Status-LED + Error LED on = selftest failure
The self-test, which is performed after each start or reset of the
Web-IO 8x Thermometer, could not be correcly finished due to
an incomplete firmware update. The device is no longer operational in this state. Please return the unit.

2 TCP/IP Configuration
Once the hardware has been configured as described above,
the IP address necessary for operating in a TCP/IP network
must be assigned. Please request the correct value for this parameter from your system administrator.
!
The IP address must be unique throughout the network.
2.1 Assigning the IP address ...
There are five ways to first assign the IP address for the Web-IO
8x Thermometer:
2.1.1 ... using WuTility
First download the „WuTility“ tool from the WuT Homepage:
(http://www.wut.de)
Be sure that the PC you are using to assign the IP address is in
the same subnetwork as the device and that both the PC and
the device are connected to the network.
- Start „WuTility“ and click on the scan icon:
- Select your Web-IO Thermometer from the displayed list using
the MAC address:
W&T
14
2.1.2 ... using DHCP-/BOOTP protocol
Many networks use DHCP (Dynamic Host Configuration Protocol) or BOOTP for centralized and dynamic assignment of the
IP addresses. Which of the two protocols are used makes not
difference to the Web-IO devices, since DHCP is simply a downward compatible extension of BOOTP. DHCP servers thus also
use the requirements of BOOTP clients.
The MAC address is found on the label affixed to the housing:
- Click on the „Assign IP Address“ symbol:
- In the resulting window,k enter the desired IP address for the
device and confirm with „OK“: :
The device acknowledges the entry with an audible tone (2x/
8x Thermometer only) and accepts the set IP address. After
clicking again on the Scan button, this address is displayed in
the WuTility.
5xxxx [Typ]
EN=00c03d004a05
OK xxxxxx
Ethernet-address
W&T
Subject to errors and modifications
15
The following parameters can be assigned to the Web-IO 8x
Thermometer using these protocols:
■ IP address
■ Subnet mask
■ Gateway address
It is not possible to assign other parameters or a lease time.
Functionality
To obtain an IP address, the device sends after every new start
a corresponding BOOTP request as a broadcast to the network.
The resulting reply generated by the DHCP/BOOTP server contains in addition to the IP address the subnet mask and gateway address. The Web-IO 8x Thermometer immediately places
this information in its non-volatile memory.
When placing the unit into service in DHCP/BOOTP networks,
please consult with your system administrator. If DHCP will be
used for assigning the address, you must mention that a reserved IP address is required. To maintain the respective address
database, the administrator needs the Ethernet address of the
Web-IO 8x Thermometer, which can be found on the sticker on
the housing.
Once the necessary entries have been made, the device automatically obtains the desired IP address after each reset. To ensure that the Web-IO 8x Thermometer can also be reached if
the DHCP/BOOTP server fails, the previous IP address is retained if no reply follows.
W&T
16
!
In DHCP environments the IP address to be assigned
must be reserved by means of a fixed link to the
Ethernet address of the Web-IO 8x Thermometer.
Under Windows NT this is done in the DHCP Manager
under menu item „Reservations“. Linux provides the file
„dhcpd.conf.“ for this purpose, in which a corresponding
entry must be made.
2.1.3 ... using ARP command
The requirement is a PC which is located in the same network segment as the Web-IO 8x Thermometer and which
has TCP/IP protocol installed. Read the MAC address of
the device on the device (e.g.. EN=00C03D0012FF). Under
Windows you first ping another network station and then
insert the command line shown below into the ARP table
as a static entry:
arp -s <IP-address> <MAC-address>
e.g. under Windows:
arp -s 172.0.0.10 00-C0-3D-00-12-FF
e.g. under SCO UNIX:
arp -s 172.0.0.10 00:C0:3D:00:12:FF
Next ping the device again (in our example ping
172.0.0.10). The address is now stored in non-volatile memory.
!
This method can only be used if no IP address has yet
been assigned to the Web-IO 8x Thermometer, i.e. the
entry is 0.0.0.0. To change an already existing IP
address, you must open the configuration menu through telnet
or select the serial path (2.1.4).
W&T
Subject to errors and modifications
17
2.1.4 ... over the serial interface
In contrast to the procedure described above, you can change
an already existing IP address for the Web-IO 8x Thermometer
over the serial interface.
Connect the RS232 port on the unit to a PC and start a terminal
program (e.g. Hyperterminal). Establish a direct connection
through your COM port and set the serial properties 9600 baud,
no parity, 8 bits, 1 stop bit, no protocol. Perform a reset by interrupting the supply voltage on the unit. When the green Status LED comes on, enter (on the terminal) the letter „x“ at least
three times until the message „IPno.+<Enter>“ appears. Now
enter the IP address in the usual decimal format
(xxx.xxx.xxx.xxx) and confirm your entry with <Enter>.
!
Backspacing will not correct an error in entering text.
The procedure must be repeated.
If the entry was correct, the assigned IP address is acknowledged, otherwise the monitor shows the current IP address along
with the message „FAIL“. This procedure may be repeated as
often as desired.
If you want to shut down the BOOTP (DHCP) functionality in
this status directly, type a „-0“ behind the IP-address
(192.168.5.12-0).
You will need a null modem cable for connecting to a terminal:
xxx -> Web-IO Thermometer
IP no.+<ENTER>: <- Web-IO Thermometer
172.17.231.99-0 -> Web-IO Thermometer
172.17.231.99 <- Web-IO Thermometer
W&T
18
2.1.5 ... using an RARP server (UNIX only)
Working with an RARP server activated under UNIX is based on entries in the configuration files /etc/ethers and
/etc/hosts. First add a line to /etc/ethers with the allocation of
the Ethernet address of the Web-IO 8x Thermometer to the
desired IP address. In /etc/hosts the link with an alias name is
then created. Once you have connected the device in the network segment of the RARP server, you can assign the desired IP
address over the network.
Example:
Your Web-IO 8x Thermometer has MAC address
EN=00C03D0012FF (sticker on the unit). You want it to
have IP address 172.0.0.10 and the alias name WT_1.
Entry in file /etc/hosts: 172.0.0.10 WT_1
Entry in file /etc/ethers: 00:C0:3D:00:12:FF WT_1
If the RARP deamon is still not activated, you must start it
using the command „rarpd -a“.
A crossed serial cable is needed to connect the device to a terminal:

!
To make the subnet mask and gateway settings, the con
figuration PC must be located in the same IP sub-network
as the Web-IO Thermometer. Otherwise no communicati-
on with the device will be possible.
Once you have assigned the IP address, set the subnet mask
and gateway as follows:
1. Open a Web browser and enter the IP address of the device
in the address line.
2. Select Config. in the configuration menu
3. Since no password has yet been assigned, leave this line
blank and confirm by clicking on the Login button and then
„OK“.
4. Select the following path in the menu:
Config -> Device -> Network
5. Now enter the subnet mask and gateway and confirm using
the Send button.
2.2 Setting the subnet mask and gateway
When working in routed environments, the Web-IO Thermometer must also be told which subnet mask is valid for the respective network segment and which router is being employed. You
can obtain the valid values for both parameters from your system administrator.
The subnet mask and gateway can be set after assigning the IP
address using the Web-Based Management tool (3.2.1).

6. Select the following path in the menu:
Config -> Session Control -> LogOut
and click on the Save button.
The device has now saved your settings.
2.3 Connecting the Web-IO 8x Thermometer
In an Intranet
Once all the settings have been made, the Web-IO 8x Thermometer can be accessed through any desired Web browser. Enter
as an address the IP address or (if you have specified a corresponding DNS entry) the host name for the device. The device
will then send its information back to the browser.
In the Internet
To make the Web-IO 8x Thermometer accessible from the Internet, you will need a free, external and static IP address which
your router can reach from the Internet. Ask your ISP to provide
you with a DNS entry so that the Web Thermometer can be accessed by means of a URL. Then you need only to divert HTTP
port 80 in your router to the IP address of the Web-IO 8x Thermometer. This is done by means of an entry in the NAT table,
such as:
http 172.0.0.10

3 Configuring the Web-IO 8x Thermometer
Once all the hardware settings are made, you can go to the Web
configuration of the Web-IO 8x Thermometer. Start a Web browser and in the address line enter the IP address of the device:
http://172.0.0.10/
The Web-IO 8x Thermometer starts with the following display:
After clicking on „Login“ in the menu, you are asked to
enter a password.
