  • Page 15: Tcp/Ip Configuration

    W&T TCP/IP Configuration Following the hardware installation, this section describes the logical integration of the LAN-Modem into the TCP/IP network. Assigning the IP address Setting the Subnet-Mask and Gateway You can obtain all the parameters from the system administrator of your network.

  • Page 16: Assigning The Ip Using The „Arp" Command

    W&T TCP/IP Configuration 3.1 Assigning the IP using the „ARP“ command This method can only be used if the LAN-Modem does not yet have an IP address, i.e. the current 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 via TELNET.
  • Page 17 W&T TCP/IP Configuration The LAN-Modem accepts the IP address of the first network packet sent to it as its own and saves it in non-volatile RAM. Every IP address must Only now is the Telnet connection established and the be used only once in the network.

  • Page 18: Assigning The Ip Through The Serial Port

    W&T TCP/IP Configuration 3.2 Assigning the IP through the serial port After the LAN-Modem has been reset, a time window of approx. 1-2 seconds is provided during which you can assign a new IP address by entering at least three „x“. In contrast to the previously described using ARP, this serial path works regardless of whether the L A N - M o d e m a l r e a d y h a s a n I P a d d r e s s o r n o t .

  • Page 19: Serially Deactivating The Dhcp-/Bootp-Client

    W&T TCP/IP Configuration 3.2.1 Serially deactivating the DHCP-/BOOTP-Client The DHCP-/BOOTP function of the LAN-Modem can be turned off when serially assigning the IP address. We recommend doing this in all cases where it is not absolutely necessary to use DHCP/BOOTP to assign the IP. To deactivate the DHCP-/BOOTP client, attach the option „-0“...

  • Page 20: Assigning The Ip Using An Rarp Server

    W&T TCP/IP Configuration 3.3 Assigning the IP using an RARP server UNIX environments in particular often use the RARP protocol for centralized assignment of IP addresses. This means that TCP/IP devices that want to obtain an IP address send RARP requests with their Ethernet address as a broadcast over the network.

  • Page 21: Assigning The Ip Using Dhcp-/Bootp Protocol

  • Page 22: Deactivating The Dhcp-/Bootp Protocol

    W&T TCP/IP Configuration After the administrator has made the necessary entries, the LAN-Modem will automatically obtain the desired IP address after each reset. To ensure the availability of the LAN-Mo- dem even should the DHCP/BOOTP server fail, the previous IP address is kept if no reply comes. In DHCP environments the IP address to be assigned must be reserved by means of a fixed link to the Ethernet address of the LAN-Modem.
  • Page 23 W&T TCP/IP Configuration • The serial port is used to assign the IP address for the LAN-Modem. By sending „xxx“ to the LAN-Modem during a restart, you arrive at the input mode for a new IP address. If you enter this followed by the string „-0“, the BOOTP client of the LAN-Modem will be deactivated (see Older Windows systems will only...

  • Page 24: Configuring The Subnet Mask And Gateway

    W&T TCP/IP Configuration 3.5 Configuring the subnet mask and gateway When working in routed environments, the LAN-Modem must be told the responsible router in addition to the subnet mask which is valid for the respective network segment. Valid values for both parameters can be obtained from your systems administrator.
  • Page 25 W&T TCP/IP Configuration The entry fields for the subnet mask and the gateway address are reached through the following menu path: 1. INFO Com Server 2. SETUP System 1. Setup TCP/IP 1. IP-Address 2. Set Password 2. Subnet Mask 3. SETUP Port 0 3.

  • Page 27: Modem Operation

    W&T Modem Operation After the netework 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.

    W&T Appendix The Modem Protocol on the TCP Level Normally LAN-Modems will be used only to connect to each other. It is however conceivable that an application program uses TCP/IP programming to direct dial an individual LAN-Modem or to be called by the LAN-Modem. The information required for doing this can be obtained on request.
