How to install CU-960

When to use CU-960

The CU-960 controller is an interface to connect chromatography or synthesis instruments to a PC. CU-960 is used primarily together with ÄKTAprocess instruments. It features a Profibus interface, a standardized and efficient serial fieldbus which is optimized for process automation applications.

The LEDs on CU-960

There are three LEDs on the front of the CU-960 which can be in three different states:

  • Off (no light)

  • Flashing, with different flash rates

  • On (steady light)

The table below describes what the state of each LED means.

  • Flash rate 2 Hz: No contact with ÄKTA system

  • Flash rate 0.5 Hz: No contact with Profibus system

  • Flash rate 1 Hz: No contact with both ÄKTA and Profibus systems

Contact with systems established

BIT = Built-in test

Note: The system LED will flash while the system is scanning to identify all components. At the same time the run data instruments in the System Control module will read Scanning. When the scanning process is completed, the system LED will stop flashing and the instruments will read Ready. If any instrument component causes an error or is missing, this will be indicated in the UNICORN System Control module during the test.
CU-960 USB and CU-960 Advanced

There are two versions of the CU-960 controller, USB and Advanced. The table below describes how they connect and how many that can be connected to the PC.

Step

Action

1

  • Start and log on to the PC.

  • Connect the CU-960 power cable to the mains socket and wait until the LEDs show that it has started up:

    Power LED: On (steady light)

    PC LED: Flashing

    System LED: Flashing

  • Connect the USB cable to the CU-960 and the PC.

2

Since this is the first time you connect the CU-960, the Found New Hardware Wizard is started.

  • Select the option Install the software automatically.

  • Click the Next button.

3

  • Select Search for the best driver in these locations.

  • Select only Include this location in the search.

  • Insert the UNICORN CD into the CD-ROM drive of the PC.

  • Click the Browse button and locate the folder \\Drivers\Cu950 Cu960.

  • Click the Next button.

    Result: The necessary files are copied to the hard disk.

The Completing the Found New Hardware Wizard screen is displayed.

  • Click the Finish button to complete the installation.

Note: CU-960 uses the same driver as CU-950.
CU-960 system installation

To be able to control a system (an instrument) with the CU-960 controller the UNICORN software has to be set up accordingly. Usually this is done when the UNICORN software is installed for the first time, but it can also be done afterwards.

System installation during UNICORN software installation

The system installation part of the UNICORN software installation is described in Step 11 - System Installation.

System installation after UNICORN software installation

The table below describes how to perform a CU-960 system installation after the UNICORN software has been installed.

Step

Action

1

  • Insert the UNICORN CD in the CD-ROM drive.

Result: The Setup wizard starts and displays the Welcome screen.

  • Click the Next button.

2

The Select Components screen is displayed.

  • Make sure that the System Installation option is selected. You should deselect the other check boxes unless you want to install other components.

  • Click the Next button.

3

The Program Options screen is displayed.

  • Specify the number of System Control Windows you want to be available, normally the number of instruments that will be simultaneously connected to the PC.

    Maximum value is

    1 for CU-960 USB

    4 for CU-960 Advanced.

  • Click the Next button.

4

The Start Copying Files screen is displayed.

  • Click the Next button.

5

The System installation screen is displayed.

CU-960 Advanced port numbers

The TCP ports used by UNICORN for the CU-960 Advanced are numbered 60X01-60X33, where X is the CU ID minus 1.

Example

  • The CU ID = 1 (default)

  • => X = 1 - 1 = 0

=> The TCP port numbers used on the PC and on the CU = 60001-60033
