    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.

  • Page 18: Ip Configuration With Wutility

    3.1 IP configuration 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 configurations, the ability to perform firmware updates, managing configuration profiles, etc.

  • Page 19: Step 1: Start The Assignment Dialog

    • 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.

  • Page 20: Step 2: Assign The Ip Parameters

    Step 2: Assign the IP parameters The Static option allows you to assign fixed 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 fields. 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).

  • Page 21: Ip Assignment Using Dhcp Protocol

    3.2 IP assignment using DHCP Protocol DHCP protocol is activated by the factory default settings, so that in network environments dynamic IP assignment is suffi- cient for connecting the device to the network. The following parameters can be assigned using DHCP: •...

  • Page 22: System Name

    3.2.2 System name the DHCP server, the device identifies itself within the DHCP protocol with its system name. The factory default setting for this is WEBIO- followed by the last three places of the Ethernet address. For example the factory set system name of a device with the Ethernet address 00:c0:3d:01:02:03 is WEBIO-010203.

  • Page 23: Ip Assignment Using Arp Command

    3.3 IP assignment using ARP command Requirements This method can only be used if the device does not already have an IP address, i.e. the entry is 0.0.0.0. To change an IP address, use one of the other methods described in this section or use the configuration menu over web based management.

  • Page 24: Step 2

    Insert a static entry into the ARP table of the computer using the following command line: arp -s [IP address] [Etherenet address] E.g. under Windows: arp -s 172.16.231.10 00-C0-3D-00-12-FF E.g under UNIX/Linux: arp -s 172.16.231.10 00:C0:3D:00:12:FF 1 T h e I P a d d r e s s e s m u s t b e w i t h o u t l e a d i n g z e r o s i n all Windows environments.
  • Page 25 The device takes the IP address of the first network packet sent to it as its own and saves it in non-volatile memory. The ping requests of the PC are then replied. It is not possible to configure the subnet mask and gateway address using a static ARP entry.

  • Page 26: Ethernet Interface

    4 Ethernet interface The Web-Thermometer incorporates an IEEE 802.3-compatible network interface. 4.1 Link status The Link status is indicated on the two LEDs built into the RJ45 jack. • Link/Activity (green) ON indicates a valid link to a hub or switch port. The LED flashes when there is data traffic.
