Safety for Users12
More safety-relevant information is listed below:
flammability: Organic solvents are highly flammable. Since capillaries can
detach from their screw fittings and allow solvent to escape, it is prohibited to have any open flames near the analytical system.
solvent tray: Risk of electrical shock or short circuit if liquids get into the
device's interior. For this reason, place all bottles in a solvent tray.
solvent lines: Install capillaries and tubing in such a way that liquids can-
not get into the interior in case of a leak.
leaks: Regularly check if any system components are leaking.
power cable: Defective power cables are not to be used to connect the
device and the power supply system.
self-ignition point: Only use eluents that have a self-ignition point higher
than 150 °C under normal ambient conditions.
power strip: If several devices are connected to one power strip, always
consider the maximum power consumption of each device.
power supply: Only connect devices to voltage sources, whose voltage
equals the device's voltage.
toxicity: Organic eluents are toxic above a certain concentration. Ensure
that work areas are always well-ventilated! Wear protective gloves and
safety glasses when working on the device!

Computer Control
This section describes how to set up an HPLC system in a local area network
(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.
Note: To set up a LAN, we recommend to use a router. That means the following steps are required:
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 deactivated for all USB hosts.
Only for Windows 7: For the network adapter, the option "Allow the
computer to turn off this device to save power" in the Device Manager
must be deactivated.
Process1. In Windows 7 choose Start

2. Double-click on LAN Connection.
3. Click on the button Properties.
4. Select Internet Protocol version 4 (TCP/IPv4).
5. Click on the button Properties.
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 company net-
work or the Internet. In contrast, the LAN ports serve to set up a network
from devices
operating the HPLC system separately from the company network.

which is not supplied within the scope of delivery.
There is a patch cable for each device and the computer.
Process1. Use the patch cable to connect the router and the computer. Repeat this
step to connect all devices.
2. Use the power supply to connect the router to the mains power system.

25Installation
4. In the router configuration, check the IP address range and make
changes if necessary.
ResultOnce the router has assigned IP addresses to all devices, the chromatogra-
phy software can be used to remotely control the system.
Integrating the LAN into a Company Network
A network administrator can integrate the LAN into your company network.
In this case you use the WAN port of the router.
PrerequisiteThere is a patch cable for the connection.
Process1. Check that the IP address range of the router and of the company net-
work do not overlap.
2. In case of an overlap, change the IP address range of the router.
3. Use the patch cable to connect the router WAN port to the company network.
4. Restart all devices, including the computer.
Controlling Several Systems Separately in a LAN
Devices connected to a LAN communicate through ports, which are part of
the IP address. If more than one HPLC system is connected to the same LAN
and you plan on controlling them separately, you can use different ports to
avoid interference. Therefore, the port number for each device must be
changed and this same number must be entered into the device configuration of the chromatography software. We recommend to use the same port
number for all devices in the same system.
Note: The port is set to 10001 at the factory. You must use the same numbers in the device configuration of the chromatography software as in the
device, otherwise the connection fails.
Process1. Find out port number and change it on the device.
2. Enter the port number in the chromatography software.
ResultThe connection is established.
Setting a Static IP Address
Note: Please inform yourself about the IT safety standards valid for your lab-
oratory, before changing the LAN settings.
The device is factory set to a dynamic IP address (DHCP). To ensure a per-
manent LAN connection between the chromatography software and the
device, we recommend to set a static IP address for certain applications.
Prerequisites The device has been switched on.
Mobile Control has been installed and started.
The connection between the Mobile Control and the device has been
established.
