Setting the IP address of the ChemWeb Server
Initialization of the ChemWeb Server after switching on the power supply or after a reset may take up to several minutes depending on the configuration! During this time the ChemWeb Server does not respond!
The ChemWeb Server must be installed completely before the initial startup!
Before starting the setup of a connection, it must be decided which type of connection is to be used for the connection to the ChemWeb Server. There are four different types of connection to the ChemWeb Server:
-Network connection in a LAN
-Direct network connection
-Switched connection via modem
-Null modem connection via serial interface
Network connection in a LAN
The connection to the ChemWeb Server can be set up from any laptop computer/PC in the network. It is assumed that the laptop computer/PC to be used is already installed as user of the network. As a fixed IP address and a network mask are always preset at the ChemWeb Server before leaving the factory, these must be adapted to the network. For this purpose, the supplied CD or floppy disk is required. The IP address and network mask preset at the ChemWeb Server in the factory are:
IP address: | 192.168.200.4 |
Network mask: | 255.255.255.0 |
The ChemWeb Server is connected to a network switch or hub using a standard patch cable. If an uplink port is available at the network switch or hub, the supplied crossed patch cable can also be used.
The required parameters (IP address, network mask, DHCP) must be provided by the network administrator. To change the IP address, the network mask or the DCHP operating mode of the ChemWeb Server,
Direct network connection
The connection is always set up between a laptop computer/PC with network board (10MB/s) and the ChemWeb Server via the supplied null modem cable. The supplied CD or floppy disk is only required if the fixed IP address and/or network mask preset at the ChemWeb Server in the factory cannot be used. A fixed IP address and network mask must be assigned to the laptop computer/PC. The ChemWeb Server and the laptop computer must always have the same network mask and an IP address in the same address range. The IP address must, however, not be identical for both.
Example: | Laptop computer/PC | |
| ||
192.168.200.4 | 192.168.200.1 | |
Network mask: | 255.255.255.0 | 255.255.255.0 |
If the IP address or/and the network mask of the ChemWeb Server are to be changed,
With WindowsXP, a network connection is set up automatically as soon as a network board is identified in the laptop computer/PC. Just a fixed IP address and a network mask have to be assigned manually.
