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

sensor

Plug the sensor included in the scope of delivery into the 9-pin IO terminal on the unit.

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:

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.

W&T

Subject to errors and changes

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

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.

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.

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.

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.

3.11.1 Basic Settings -> FTP

Here you will find the basic settings needed for FTP mode

FTP Server IP: Enter here the IP address or the host name of the FTP server you want to send the data to.

FTP Control Port: This is the port needed for the connection. The standard port for FTP access is 21. This port is already preset and should function on most systems at the first go. If you require a different port, please consult your network administrator.

User: Enter here the user name required for the FTP access.

Password: This is the password assigned to the user.

FTP Account: Some FTP servers require a special Account entry

for the login. If this is the case with your server, enter the Account name here.

Options / PASV: If this option is enabled, the server is instructed to operate in passive mode. This means the data connection is opened by the Web-Thermograph. If this option is disabled, the FTP server takes over opening of the data connection. If the server is protected by a firewall, it is recommended that the PASV option be enabled, since otherwise connection attempts could be blocked.

3.13 ASCII command strings via TCP Port 80

3.13.1 HTTP

When queried by means of an HTTP-Get command, the device can also send a header with IP address and device name in addition to the temperature. To do this, check the appropriate box. Only the temperature is sent if this function is deactivated.

W&T

Subject to errors and changes

The setting of the header which can be appended to the temperature in messages applies here as well.

3.14 ASCII command strings via UDP

In addition to TCP/IP comands, the device can also reply to UDP datagrams. For this you must set the port you want the device to „listen“ to. The default setting is 42279. The enable function activates UDP.

W&T

3.15 UP-/Download

In the download area you can download the XML configuration as well as the three user pages (home.htm, user.htm, log.htm) for further processing.

With XML-Download you can read out the settings of the WebThermo-Hygrograph and make any modifications, and XML Upload allows you to store the settings again in the device.

With some Web browsers the correct code is only output

using the path „View-> Display (Frame-) Source text“ after the „XML Download“ button has been clicked.

For XML upload you create or modify a text file with the corresponding parameters and load this file into the device. The configuration of the 8x Thermometer must beging with the expression

<io-ANTFB1.3>

and end with the expression

</io-ANTFB1.3>

The sequence of the parameters you set corresponds to the sequence of the configuration menu starting at „Device“.

The syntax for configuring via XML is as follows:

<parameter1> VALUE </parameter1>

<parameter2> VALUE </parameter2>

</option>

W&T

Subject to errors and changes

The individual options and parameters correspond to the configuration items in the browser menu.

Please note, especially in the case of mass updates and configurations, that the IP address stored in the XML file is also sent, which only needs has to be adapted.

In addition, you can exchange the user pages (user.htm, home.htm, log.htm) in the Upload area.

An example can be found in the Appendix (6.2).

Use the menu point„Upload -> GIF“ to replace the logo displayed in the menu and store it directly in the device.

4 Single querying of temperatures

4.1 Querying temperature via TCP/IP

It is possible to use a socket connection to manually query the current temperature values in CSV (comma-delineated data). This function is also used to query the individual data without the Web interface.

To do this, send the following string to Port 80:

GET /Thermo.csv

To query the individual, current temperature value, send the string:

GET /Single1

To query the individual, current rel. humidity value, send the string:

GET /Single2

To query the individual, current air pressure value, send the string:

GET /Single3

4.2 Temperature querying via UDP

Open a UDP connection to the device IP address or to the NetID as a broadcast and Port 42279 (default setting can be changed).

Then send the device one of the expressions given under 4.1 and the device will return the temperature to the port you are using.

W&T

Subject to errors and changes

4.3 Temperature querying using SNMP

The sensor can be queried directly using SNMP-Get requests. They reach the sensor via the following path:

<IP-address> 1.3.6.1.4.1.5040.1.2.16.1.3.1.1.1 = temperature as octet string

<IP-address> 1.3.6.1.4.1.5040.1.2.16.1.4.1.1.1 = temperature as 3 digit integer value, without conmma delineation.

<IP-address> 1.3.6.1.4.1.5040.1.2.16.1.3.1.1.2 = relative humidity as octet string

<IP-address> 1.3.6.1.4.1.5040.1.2.16.1.4.1.1.2 = relative humidity as a 3-digit integer value, without comma delineation.

<IP-address> 1.3.6.1.4.1.5040.1.2.16.1.3.1.1.3 = air pressure as octet string

<IP-address> 1.3.6.1.4.1.5040.1.2.16.1.4.1.1.3 = air pressure as a 5-digit integer value, without comma delineation.

For querying, specify the configured SNMP Read

or Read/Write community.

An MIB for incorporation into management applications can be downloaded from the data sheeet page for the device at the WuT homepage http://www.wut.de.

When using multiple devices, it may be practical for broadcast transmissions to include the name and IP address of the device as well. To do this,

activate „GET Header enable“ under „Config >> Device >> Basic Settings >> HTTP“.

W&T

If you want to make changes in the device via SNMP (IP address, subnet mask, etc.) you must first start a session on the device using your SNMP manager.

m If you have assigned an administrator password, you must

enter it in your manager software as a „community string“!

Entering the administrator passwortd in the variable

wtWebGraphThermoBaroSessCntrlPassword

opens a session. By reading out the variable

wtWebGraphThermoBaroSessCntrlConfigMode

you can check whether the session was successfully opened.

1 = Session opened, device in configuration mode. 0 = Opening of the session failed. Check whether you entered

the password incorrectly.

After successfully opening the session, you can use the variables defined in the private MIB to make any configuration changes.

Once you have finished with configuration, write the variable

wtWebGraphThermoBaroSessCntrlLogout

to close the session.

wtWebGraphThermoBaroSessCntrlLogout =

1 All changes are saved 2 Quit without saving

W&T

Subject to errors and changes

If no SNMP communication takes place over a period of 5 minutes during an open session, the device unilaterally ends the session and all changes are cancelled.

Opening an SNMP session has priority over an HTTP login. This means: A user with Config or Administrator rights loses his browser access as

soon as an SNMP session is opened.

The description for the individual SNMP variables, OIDs etc. can be found in the Private-MIB.

W&T

The RGB value is given as a 24-bit hex value.

e.g.:Value="#2F3C09" This is not case-sensitive.

This is not case-sensitive.

If a parameter is omitted or incorrectly set, the following standard values are used

5 Placing the temperature into your own web page

It is possible to use an implemented Java applet to integrate the temperature on your own Web page. The applet is refreshed every 60s. An example for this applet is already in the device:

http://172.0.0.10/app.htm

To incorporate the applet for temperature monitoring into the HTML page, the following HTMP tag must be inserted at the point where the applet will be incorporated:

<Applet Archive="A.jar" Code="A.class" Codebase="Http://

WebTherm

Width="

The sensor is selected using the parameter

The unit (for example for the humidity sensor) is specified by the parameter

The parameter is a string type. If it is not specified, a „C“ is automatically set.

If you want to use your own Java functions which access multiple device applets, you can use the parameter

to number the applets for each device begining with 0.

Turning polling of the sensors off and on is accomplished using the parameter

or „off“. The default setting is „on“.

If you use a different polling rate than the default 60 seconds, use the parameter

in units of ms. Note that no sooner than every 60 seconds for the Web-Thermograph and every 4 seconds for the Web-Thermograph 2x/8x a new value is available.

W&T

To output an error message when there are problems opening a connection, use the parameter

or „off“ to turn this on or off. The default value is „off“.

Once all the parameters are defined, you must close the HTMP tag with </Applet>.

Example:

<Applet Archive="A.jar" CODE="A.class"

Codebase="http://192.168.0.10" Width="300" Height="100">

</Applet>

The font size is automatically determined by the size of the applet.

5.1 Controlling the Java applet with JavaScript

To be able to use control of the Java applet with JavaScript, the addition „mayscript“ must be specified in invoking the applet:

<Applet Archive="A.jar" CODE="A.class"

Codebase="http://192.168.0.10" Width="300" Height="100"

mayscript>

In order to work with the applet the corresponding JavaScript function must be declared in the header of the Web page.

W&T

Subject to errors and changes

The following reading function is used for this:

function sensorChanged( iDevice, iSensor, iVal )

{ Program code run when there is a change on the inputs

The above function is invoked by the applet when a temperature change on the sensors is detected. iDevice specifies for which Web-Thermograph a value changed. iSensor is used to indicate which sensor changed. The variable iVal transmits the current temperature value.

Please note that the names of the functions are

case-sensitive

The following source text shows a small example for dynamic display of Sensor 1.

6 Data logger

The Web-Thermo-Hygrobarograph stores all the measured values in a non-volatile ring memory, so that they are retained even after loss of power or actuating the reset button.

The measured data in the data logger are recalled

through the user page of the device (Home -> User or http://xxx.xxx.xxx.xxx/user.htm).

Under Config -> Device -> Data Logger -> Memory you can clear the memory.

An interruption of the timeline, caused for example by a reset or subsequent time server synchronization, is shown on the data logger page as a yellow line.

When alarm limit values are set, temperatures which

are not within the valid range are highlighted in red.

time line interruption: yellow marked line

7 Appendix

7.1 Alternate methods of IP address assignment

7.1.2 ...Using ARP command

The prerequisite is a PC which is located in the same network segment as the Web-Graph 1x Thermo-Hygrometer and on which TCP/IP protocol is installed. Read off the MAC address of the device from the nameplate (e.g. EN=00C03D0012FF). Under Windows you will first ping another network station and then use the command line described below to make a static entry in the computer‘s ARP table:

arp -s <IP-Adresse> <MAC-Adresse>

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

Now ping the device again (in our example, ping 172.0.0.10). The IP address is now stored in non-volatile memory.

This method can only be used if no IP address has as yet been assigned to the Web-Graph 1x Thermo-Hygrometer,

in other words the entry is 0.0.0.0. To change an already existing IP address, you must open the configuration menu from your browser or use the serial method (see below).

W&T

Subject to errors and changes

7.1.3 ...Using a serial interface

In contrast to the procedure described above, you can use the serial port to change an already existing IP address for the WebGraph 1x Thermo-Hygrometer.

Connect the RS232 port on the device to a PC (null modem cable, with the Web-Graph 1x Thermo-Hygrometer only pins 2, 3 and 5 are allowed to be connected) and start a terminal program (e.g., Hyperterminal). Establish a direct connection in the program through your COM port and set the serial properties to 9600 baud, no parity, 8 bits, 1 stop bit, no protocol. Force a reset by interrupting power while holding down the „x“ key until the reply „IPno.+<Enter>“ appears. Enter the IP address using conventional notation (xxx.xxx.xxx.xxx) and finish the entry with <Enter>. You can also enter the subnet mask and gateway and turn the BOOTP client off directly by using the following syntax after the entry prompt (IPno.+<Enter>):

<IP-Adresse>,<subnetmask>,<gateway>-0

If you make a typing error when entering, the text cannot

be corrected using the Backspace key. The procedure must be repeated.

If the entry was correct, this is acknowledged by the assigned parameters, otherwise the monitor displays the current IP address together with the message „Fail“. This procedure may be repeated as often as desired.

To turn off the BOOTP (DHCP) functionality directly, enter the expression „-0“ directly following the parameters (e.g.

192.168.1.2-0)

7.1.4 ...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 expand /etc/ethers by one line with the assignment of the Ethernet address of the Web-Thermo-Hygrobarograph to the desired IP address. In /etc/hosts the link with an alias is then specified. After you have connected the device in the network segment of the RARP server, you can assign the desired IP address to the device over the network.

Example:

Your Web-Thermo-Hygrobarograph has MAC address EN=00C03D0012FF (sticker on the housing). You want it to have IP-Address 172.0.0.10 and the alias WT_1 .

Entry in the file /etc/hosts: 172.0.0.10 WT_1

Entry in the file /etc/ethers: 00:C0:3D:00:12:FF WT_1

If the RARP daemon is not yet activated, you must start it using the command „rarpd -a“.

W&T

7.2 Example for creating your own Web pages

You can freely configure the standard display pages of the device (user.htm, home.htm, log.htm). Special control elements let you insert tags into the page. The following shows an example for creating the „user.htm“ page.

Create an HTML file which must begin with the expression

<user.htm> (or log.htm oder home.htm)

Then enter the HTML code.

You can display the following parameters on your pages:

<w&t_tags=t1>

7.3 Firmware Update

The Web-Thermo-Hygrobarograph firmware is under continuous development. The following section describes the procedure for uploading new firmware as it becomes available.

. Where to I obtain the current firmware?

. Firmware update over the network using Windows

7.3.1 Where do I obtain the current firmware?

The most up-to-date firmware including the necessary update tools and a revision history are published on our Web pages under the following address: http://www.wut.de

Before downloading, write down the 50digit type number for the Web-Thermo-Hygrobarograph found on the part label. From the homepage you go to the product overview, which is sorted by article number and from which you can get directly to the data sheet for your unit. From there follow the link to the current firmware version.

7.3.2 Firmware-Update over the network

using Windows

The prerequisite is a PC running under Windows 9x/NT/2000/XP with a network connection and activated TCP/IP stack. For the update process you will need twofiles whyich, as already described, can be downloaded from the homepage http:// www.wut.de.

· The executable update tool for sending the firmware to the Web-Thermo-Hygrobarograph

· The file with the new firmware which you want to send to the Web-Thermo-Hygrobarograph

W&T

Subject to errors and changes

No special preparation of the Web-Thermo-Hygrobarograph is necessary to perform the firmware update.

The WuTility used for the update detects all the WuT devices in your network and is essentially self-explanatory. If you do have any questions or if anything is unclear, please use the associated documentation or our online help.

Never intentionally interrupt the update process by

disconnecting the supply voltage or pressing the Reset button. After an incomplete update the Web-Graph Thermo-Hygrometer will be incapable of functioning.

Never mix files having different version numbers in the file name. This will result in malfunction of the device.

The Web-Thermo-Hygrobarograph automatically recognizes when transmission of the new firmware is complete and automatically performs a reset.

W&T

7.3.3 LED indicators

■ Power-LED: Indicates presence of supply voltage. If the LED

does not come on, please check that the power supply is properly connected.

■ Status-LED: Flashes whenever there is network activity of the

Web-Thermo-Hygrometer. Periodic flashing indicates that the unit is ready.

■ Error-LED: The Error LED uses various flash codes to indicate

error conditions on the device or network port.

1x flashing of the Error-LED = Check network connection. The Web-Thermo-Hygrograph is not receiving a link pulse from a hub or switch. Check the cable or the hub/switch port.

2x bzw. 3x flashing of theError-LED = Perform a reset by interrrupting power. If the error cannot be cleared, reset the device to its factory defaults. Since this resets all network settings, you should first write down the existing network settings.

Config -> Session Control -> LogOut -> Restore Defaults

After a reset the device is restored to its factory defaults. Reconfigure your network settings.

Power-LED +Status-LED +Error-LED an = Self-test error

The self-test which is performed after every start or reset of the Web-Thermo-Hygrobarograph could not be correctly finished, for example due to an incomplete update of the firmware. When in this state the device is no longer operational. Please return the unit for service.
