3.2 Power supply
For power supply, use the distribution box or its respective main adapter
if no additional auxiliary device has to be powered.
Inspect the provided power cable beforehand to ensure that it is appro-
ved for your country. Replace defective power cables only with acces-
sories from KNAUER. Detachable power cables are not allowed to be
replaced with other cable types. The maximum power input is 36VA.
Device defect
No electrical insulation is provided for the interface box. Voltages
above 10 V could damage connected devices.
ÎTake protective measures.
ÎUse the device according to the specifications.
3.3 Connecting the Interface Box to acomputer
To establish a connection between the interface box and the computer,
you take the USB cable from the accessories kit and plug it into both
devices.
It is possible that your computer does not feature the correct drivers. In
this case, go to the website of the product and download the correct
drivers. The computer identifies the interface box as a serial device even
though it was connected using the USB interface. Now check for the COM
ports in the Windows device manager.
3.3.1 Including the interface box in KNAUER
chromatography software
Note: Read this segment carefully if the serial number of your interface
box is > 65000 and if you use OpenLAB®, ChromGate® or EuroChrom®
2000 for Windows. OpenLAB® and ChromGate®: Upon registration you
are asked to enter the serial number of the interface box of which you
need to enter the last 5 digits only. EuroChrom®: When the software
requests the serial number of the interface box in the hardware module,
only the last 5 digits can be seen.

Interface Box IFU 2.1 LAN Instructions V6795
3.4 Analog inputs
If the analog output of a device (e. g. 1 V integrator output of a detector)
should be connected to the analog input of the interface box, use a Cinch
cable supplied or recommended by KNAUER. Alternatively use a mat-
ching cable included with the interface box accessory kit.
Electronic defect
If the allowed maximum voltage is exceeded, the interface box
can be damaged.
ÎPay attention to the allowed maximum voltage.
3.5 Analog outputs
The analog output have to match the control input of the connected
device. The respective information has to be checked in the device inst-
ructions. Particular attention has to be paid to the allowed maximum vol-
tage, since the non-compliance of limits can damage the device. KNAUER
can not be held reliable in this case. The required components of the
remote connector are part of the accessories kit of the interface box.
3.6 Digital connections
Digital inputs can be used to forward trigger signals coming from the
injection unit. The connector for the trigger signal is the digital input of
the channel, which also serves for recording data from the detector.
Digital outputs can be programmed via control software.
The required components of the remote connector are part of the acces-
sories kit of the interface box. If you require a NO connect the contacts 1
and 2 or the contacts 2 and 3 if a NC is required, respectively (front view,
Fig. 2).
Note: If the analog input of a channel is used, it is not possible to pro-
gram the digital output of the same channel. In this case, the digital
output sends a sampled signal at the start of run that e.g. can be used as
autozero signal for a detector.
3.7 Mounting the remote connector
Follow the instructions below if you are to connect cables to the remote
connector.
1. Guide the blunt side of the depressor tool into the square opening of
the desired connector.
2. Press down the lever as indicated by the arrow.
3. Guide the non-insulated end of the cable into the opening below the
lever.

10 Unpacking and setup
Interface Box IFU 2.1 LAN Instructions V6795
4. At first let go of the lever and secondly remove the depressor tool
from the plug.
5. The cable is now well-connected to the remote connector.
3.7.1 Cable plan
The exemplary cable plan shows a possible connection scheme for the
connectors. Pay attention to the fact that the digital output and analog
input of a channel can not be used at the same time, except the analog
input is used for autozero of a detector.
