5 Establishing a connection to LDSWin
5.1 Configuring the LAN connection to LDSWin
5.1.1
Configuration of the LAN connection parameters
To communicate within a network, the LAN-Gateway needs an individual IP address, including the
corresponding subnet mask. This information is to be obtained from the network administrator
before
commissioning
the LAN gateway and is to be configured as described in chapter 4.5.1.
Only after this has been completed is the LAN gateway to be connected to the network!
For communication with LDSWin a configurable TCP/IP port is required. This can be freely selected from the
range of free ports (1024 - 65535) in accordance with the network conditions. As standard, LDSWin uses the
port 5000. If a different port is configured in the LAN gateway, then the corresponding LDSWin remote stations
must be adjusted accordingly.
For a direct network connection between the LAN gateway and a user PC, the IP address and subnet mask can
be freely selected from the private IP address range. The configuration of the PC for a direct connection of this
type is described in detail in the following chapter.
5.1.2 Direct connection with a PC via a network
A CAT5 crossover-patch cable is needed in order to make a direct connection between the LAN-Gateway and a
PC network interface.
The PC and the LAN-Gateway must be configured with an IP address from the private IP address range. The
PC, i.e. LAN gateway configuration described in the following is recommended:
A double or incorrect assignment of IP addresses and/or subnet masks can lead to
the failure of components within a network. Consequently, under all circumstances,
the LAN-Gateway must be provided with an appropriate IP address
before
connection
to the network.
In the event of a faulty port configuration no communication between LDSWin and
the LAN gateway is possible!
The use of a “Well Known Port” (0-1023) can lead to communication problems and
should be avoided!
If a connection is made via a firewall the configured TCP/IP port must be released for
the TCP/IP service.
