W&T 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.
-
W&T 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.
-
W&T 1.4 Ethernet connection The Web-Thermo-Hygrobarograph incorporates an IEEE 802.3compatible network interface on a shielded RJ45 connector. The pin assignments correspond to an MDI port, so that the connection to the hub or switch is accomplished using a 1:1 shielded patch cable. Error Serial Port Power Status U Network Power-over-Ethernet The Web-Thermo-Hygrobarograph PoE 57613 can obtain power as defined in IEEE802.3af/Power-over-Ethernet.
-
W&T 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.
-
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.
-
W&T 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.
-
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.
-
W&T 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.
-
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.
