  • Page 13: Assigning The Ip Address

    W&T Assigning the IP address The Com-Server is factory set to IP address 0.0.0.0. Before you can make the entry in the Com-Server, 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 Assigning the IP using the ARP command This method can only be used if the Com-Server 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 Telnet.
  • Page 19 W&T Assigning the IP address The Com-Server takes the IP address of the first network packet sent to it as its own and saves it in non-volatile memory. The Telnet connection will be established and the configuration menu is displayed in the Telnet window. All further settings are made here (see Basic configuration of the Com-Server).

  • Page 24: 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 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 Com-Server to the network.

  • Page 26 W&T Assigning the IP address 2.4.3 Lease-Time The lease time determined and transmitted by the DHCP server specifies the Time-To-Live of the assigned IP address. After half the lease time has expired, the Com-Server attempts to extend the time for the assigned DHCP server and up update the address.
  • Page 27 W&T Assigning the IP address 2.4.4 Reserved IP addresses If the Com-Server is used as a TCP server or UDP peer, it provides services which other clients in the network can also make use of as needed. To open a connection, they of course need the current IP address for the Com-Server, so that in such situations it makes sense to reserve a particular IP address for the Com-Server on the DHCP server.

  • Page 28: Assigning The Ip Using Bootp Protocol

    W&T Expanded services of the Com-Server 20.4 Uploading/downloading configuration data (Port numbers 8003/read, 8004/write) These services allow you to read out the configuration data for the Com-Server stored in the non-volatile memory and send it to another Com-Server. Especially when installing a large number of Com-Servers having the same settings this methjod eliminates having to open a Telnet configuration connection for each individual unit.
  • Page 182 W&T Expanded services of the Com-Server Writing configuration data on port 8004 Uploading to a Com-Server is analogous to reading out the configuration data. After opening a TCP connection to Port 8004 of the Com-Server, the latter expects the 1024 bytes for a new configuration.

    W&T Firmware update of the Com-Server 21.3 Network firmware update under UNIX Required is a computer with a network connection and a TCP/IP stack that provides Telnet and TFTP network protocols. When updating with TFTP protocol the firmware is split into 6 files that are send to the Com-Server one after the other.
