Digital Outputs (DIG.OUT)
These four outputs are electromechanical relays with single pole switch (SPDT)
meaning they are to be used as NO (normally open, connectors 2 – 3. see front
view) or as NC (normally closed, connectors 1 – 2, see front view). You can pro-
gram sampled signals or steady rate signals. A sampled signal has a duration of
appr. 1 s, the length of the steady rate signal is not predetermined.
Installation
Power Supply
The interface box is connected to a computer with an USB cable and receives
electricity from it. The USB cable is part of the accessories kit of the interface
box.
Computer defect
No electrical isolation is provided for the Interface Box. Voltages above 10 V
could damage connected computers.
Take protective measures.
Use the device according to the specifications.
Connecting the Interface Box to a Computer
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 Win-
dows device manager.
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.
