For an extended configuration of the Time Server 8030HEPTA/GPS through a browser via
WebGUI the following base parameters are required:
•
Host Name
e.g. hopf8030hepta
•
Network Configuration Type
e.g. Static IP Address or DHCP
•
IP Address
e.g. 192.168.0.20
•
Netmask
e.g. 255.255.224.0
•
Gateway
e.g. 192.168.224.1
The
hostname
must
meet the following conditions:
•
The hostname may only contain the characters 'A'-'Z', '0'-'9', '-'
and '.' . There should be no distinction between upper-and lower-
case letters.
•
The character '.' may only appear as a separator between labels
in domain names.
•
The sign '-' must not appear as first or last character of a label.
The network parameters being assigned should be pre-determined with
the network administrator in order to avoid problems on the network (e.g.
duplicate IP address).
IP Address (IPv4)
An IP address is a 32 bit value divided into four 8 bit numbers. The standard presenta-
tion is 4 decimal numbers (in the range 0...255) separated from each other by dots
(dotted quad notation).
Example: 192.002.001.123
The IP address consists of a leading network ID followed by the host ID. Four common
network classes were defined in order to cover different requirements. Depending on
the network class, the last one, two or three bytes define the host while the rest define
the network (network ID) in each case.
In the following text the "x" stands for the host part of the IP address.
Class A Networks
IP addresses 001.xxx.xxx.xxx to 127.xxx.xxx.xxx
There is a maximum of 127 different networks in this class. This allows the possibility to
connect a very high number of devices (max. 16.777.216)
Example: 100.000.000.001, (Network 100, Host 000.000.001)
Class B Networks
IP addresses 128.000.xxx.xxx to 191.255.xxx.xxx
Each of these networks can consist of up to 65534 devices.
Example: 172.001.003.002 (Network 172.001, Host 003.002)
