Connecting a device to a computer to a
Local Area Network (LAN)
Note:
HPLC devices made by KNAUER work only with IP adresses which
are assigned via IPv4. IPv6 is not supported.
This section describes how to set up an HPLC system in a local area net-
work (LAN) and how a network administrator can integrate this LAN into
your company network. The description applies to the operating system
Windows and all conventional routers.
To set up a LAN, we recommend to use a router. That means the following
steps are required:
Process
1. On the computer, go to the control panel and check the LAN proper-
ties.
2. Hook up the router to the devices and the computer.
3. On the computer, configure the router to set up the network.
4. Install the chromatography software from the data storage device.
5. Switch on the device and run the chromatography software.
Configuring the LAN Settings
The LAN uses only one server (which is normally the router) from that the
devices automatically receive their IP address.
Prerequisite
In Windows, power saving, hibernation, standby, and screen saver
must be deactived.
In case you use an USB-to-COM box, the option "Allow the computer to
turn off ths device to save power" in the devicemanager must be deac-
tivated for all USB hosts.
For all LAN devices: For the network adapter, the following option in
the Device Manager must be deactivated: "Allow the computer to turn
off this device to save power".
Process

6. Check the settings in the tab
General
. The correct settings for the DHCP
client are:
a)
Obtain IP address automatically
b)
Obtain DNS server address automatically
7. Click on the button
OK
.
Connecting the Cables
A router
3
has several LAN ports
2
and one WAN port
4
that can be
used to integrate the LAN into a wide area network (WAN), e.g. a com-
pany network or the Internet. In contrast, the LAN ports serve to set up a
network from devices
1
and a computer
5
. To avoid interference, we
recommend operating the HPLC system separately from the company
network.
