How does the Web Thermometer obtain the valid subnet mask and gateway address?

In order to be able to communicate beyond the local network, in addition to the IP address, the Web Thermometer also requires the subnet mask and gateway address applicable for the relevant sub-network. The two values must be requested from the network administrator responsible.

• Setting via the Telnet configuration menu (57601 only, Web-IO 1x Thermometer)
  If the Web Thermometer already has an IP address, then the subnet mask and gateway can be assigned and saved via the Telnet configuration (telnet [IP address] 1111] from a computer located in the same sub-network.
   
• Assignment via the serial interface
  For Web Thermometers starting from firmware version 1.37, the subnet mask and gateway address can also be configured via the serial interface. During the serial IP assignment, the values can also be specified separated by commas, with no separating spaces.
  Input example: 172.17.222.10,255.255.255.0, 172.17.222.1
   
• Assignment via BOOTP / DHCP
  In centrally administered networks, the subnet mask and the gateway can also be assigned together with the IP address via the BOOTP or DHCP server.
