50 Setup and Control of Knauer HPLC Systems
All LAN-controlled devices can be added and configured
automatically using the Auto Configuration button on the
configuration main window. Beside this, you can let the software
search for your already connected and switched-on device from the
devices configuration window. The option “Use S/N to identify the
instrument” must be enabled. Click on the button to start the
search for all connected LAN devices of the currently configured
type. If more than one will be found, all hits will be shown in the
window. Select the desired device from the shown list. The software
will read-out the information as serial number and will fill it
automatically into the configuration screen. For all Knauer LAN
devices port 10001 is selected by default. Don’t change this setting,
otherwise no communication can be established. To search for an
instrument, the device must be connected, switched on and must
have a valid IP address.
As an option, you can enter the IP address of your device, if the
option “Use S/N to identify the instrument” is disabled. Please note,
that in case the device receives the IP address from a DHCP server,
e.g. a router, the IP address may change if the device is switched off
and switched on.
Channels (available not for all detectors)
For multi-wavelength detectors more than one channel can be activated.
According to the selected number, the channel fields become accessible
for editing. The channel name will be shown later in the method window
and in the result reports. Only channels, which have been activated in the
detector configuration, will be available in the method setup later for data
acquisition.
Serial Number
If you have read-out the device via LAN, the serial number has been
added automatically. Otherwise type in the serial number of the detector
you are using. The serial number of network controlled detectors is used
for the device identification and addressing during communication. This
serial number must match the serial number of the defined pump. If not,
you will get an appropriate error message if you later try to start in run.
Y-Axis Units
Select the type of units to be displayed on the y-axis of your
chromatogram from the drop-down list. For the UV and diode array
detectors the choices are AU (Absorption Units), mAU (0.001 AU) or
µAU (0.000001 AU). For the RI detectors, the only choice is µRIU and for
the spectrofluorometric detector the units are given as a.u. (arbitrary
units).
For DAD’s you have additionally also the choice ADC counts.
Selecting this, the signal mode in the Instrument setup (page 102)
will be indicated as ‘Intensity’ without access for changing it. This
change you can perform in the configuration window only.
Flow Cell
Enter a description for the flow cell you are using. The description will be
printed out when you print the instrument configuration.
Add. Info
Click the button Add. Info... to enter more detailed description of the
detector.
