There is a patch cable for each device and the computer.
Process:
1. 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.
Configuring the Router
The router is preset at the factory. You will find a label at the bottom side of the
router, on which IP address, user name, and password are printed. These infor-
mation help to open the router configuration.
Process:
1. To open the router configuration, start your Internet browser and enter the
IP address (not for all routers).
2. Enter user name and password.
3. Configure the router as DHCP server.
4. In the router configuration, check the IP address range and make changes if
necessary.
Result:
Once the router has assigned IP addresses to all devices, the chromatography
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.
Prerequisite:
There is a patch cable for the connection.
Process:
1. Check that the IP address range of the router and of the company network
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 net-
work.
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 chroma-
