  • Page 11: Assigning The Ip Address

    W&T Assigning the IP address The LAN-Modem is factory set to IP address 0.0.0.0. Before you can make the entry in the LAN-Modem, you need to specify an IP address that is valid for your network. You system administrator will provide you with this. If you have only a small network with no routing, use the IP address of your PC and simply change the last digit.

    W&T Assigning the IP address Configuring network parameters with WuTility The Windows tool WuTility version 3.0 and higher allows not only inventorying of LAN-Modem, Com-Server and Web-IO installations, but also convenient assignment of the following network-side basic parameters: • IP address •...

This search process can be repeated manually as often as desired by clicking on the Scan button: Within the inventory list you can identify the desired LAN-Mo- dem based on its MAC address.
  • Page 14 W&T Assigning the IP address Clicking on the Next button assigns the network parameters to the LAN-Modem. After acknowledging the resulting message, all the columns in the WuTility device list are filled in with information. This concludes the network-side startup of the LAN-Modem. With the exception of a few special settings, the rest of the configuration is done as for a standard dial-up modem using the serial port and AT commands.

  • Page 15: Serial Assigning Of Ip, Subnet Mask And Gateway

    W&T Assigning the IP address Serial assigning of IP, subnet mask and gateway After a LAN-Modem reset a time window of around 2 seconds is available, during which you can assign a new IP address, subnet mask and gateway address by entering at least 3 „x“. This serial method functions regardless of whether the LAN-Modem already has an IP address or not.
  • Page 16 W&T Assigning the IP address the following example will assign IP address 172.17.231.99, subnet mask 255.255.255.0 and gateway 172.17.231.52 to the LAN-Modem. -> LAN-Modem IP no.+<ENTER>: <- LAN-Modem 172.17.231.99,255.255.255.0,172.17.231.52 -> LAN-Modem 172.17.231.99,255.255.255.0,172.17.231.52-1 <- LAN-Modem 2.2.2 Activating/Deactivating DHCP, BOOTP/RARP The DHCP and BOOTP/RARP function of the LAN-Modem can be turned off as part of assigning the IP address serially.

  • Page 17: Assigning The Ip Using Dhcp Protocol

    W&T Assigning the IP address Assigning the IP using DHCP protocol Many networks use DHCP (Dynamic Host Configuration Protocol) or its predecessor BOOTP described in the following section for centralized and dynamic assignment of the network parameters. DHCP protocol is activated by the factory default settings, so that in network environments dynamic IP assignment is sufficient for connecting the LAN-Modem to the network.
  • Page 18 W&T Assigning the IP address • Serial port As part of serial IP assignment, the following options for deactivating/activating DHCP and BOOTP can be selected directly following the address string: -0 r Deactivates DHCP and BOOTP/RARP -1 r Activates BOOTP/RARP -2 r Activates DHCP A detailed description of the procedure can be found in the section on Serial assignment of IP, subnet mask and...
  • Page 19 W&T Assigning the IP address restart therefore a corresponding update request is issued with the original DHCP server. If the latter is not resolvable at this point in time, the LAN-Modem deletes the IP address and starts a new cyclical search for alternate DHCP servers. If after the assigned lease time has expired the DHCP server is not reachable, the LAN-Modem deletes its IP address.

  • Page 20: Assigning The Ip Using Bootp Protocol

    W&T Assigning the IP address Assigning the IP using BOOTP protocol Many networks use BOOTP as predecessor of DHCP protocol for centralized and dynamic assignment of IP addresses. The factory default setting is for BOOTP turned off. You can activate it e.g.
  • Page 21 W&T Assigning the IP address Once the administrator has made the necessary entries, the LAN-Modem obtains the desired IP address automatically after each reset. To ensure accessibility of the LAN-Modem even should the BOOTP server go down, the previous IP address is retained should there be no reply.

    W&T Modem Operation After the network configuration is complete, the LAN-Modem behaves on the serial side just like a dial-up modem with an AT command set, except that the TCP/IP LAN takes the place of the telephone line. As far as the controlling application or controlling device is concerned, all that needs to happen is that the previously used telephone number is replaced by the IP address of the distant terminal.
