Knauer 2600 UV Detector: Installation

Hardware Installation

Device Connection:

Use a null modem cable (see  Null Modem Cable (RS-232-Cable) in the Appendix of the Hardware Installation section) to connect the Knauer detector. From the two RS-232 ports on the instrument's rear panel, use port 1.

Device Settings:

To configure the instrument on the Setup menu, follow the steps below:

  1. Use the arrow keys to move the cursor to the Setup menu.

  2. Press the down arrow key seven times.

  3. The Control menu is displayed.

  4. Press the right arrow key once, and then press the down arrow key until RS-232 is displayed. The other options are KNAUER.NET, RS-485, and analog.

  5. Press the right arrow key again to set the baud rate.

  6. Press the down arrow key until 9600 baud is displayed.

  7. Press the right arrow key once, and then press the left arrow key to return to the main status menu.

Restrictions:

No restrictions known.

 

Software Installation

Install the Device Driver in the Chromeleon Server Configuration. (For more information about the program, refer to Software Installation and Communication  The Server Configuration Program.)

  1. Start the Chromeleon server.

  2. Start the Server Configuration program.

  3. Add the detector to the timebase. Select Add Device on the Edit or context menu, and then select Knauer from the Manufacturers list box and Knauer_UV_Detector_2600 from the Devices list box.

  4. The following settings are required:

On the Knauer_UV_Detector_2600 tab page, verify that the Demo Mode is disabled.

On the UV_VIS_1 (UV_VIS_2) tab page, keep the name UV_VIS_1 or UV_VIS_2, respectively. Select the COM port to which the detector is connected, as well as the channel to be used for data acquisition.

On the UV tab page, keep the name UV. Select the COM port to which the detector is connected.

The Error Levels tab page classifies the severity of any errors that occur. It is generally not necessary to change the default settings.

  1. To control the Knauer 2600 UV Detector, connect the KNA_UV_2600.pan Control Panel in the Chromeleon client to the corresponding timebase.

Application

 Note:

The two analog outputs on the detector allow simultaneous acquisition of two wavelengths. As with the  Kontron 430 Detector, an oscillating grating is used. The wavelength is 190 nm to 740 nm. Entering a wavelength of 0 nm disables the channels. Thus, the oscillation of the grating is eliminated and the signal quality considerably enhanced. To enable an entry of 0 nm, the Dionex device driver supports a wavelength range of 0 nm to 740 nm. When values between 1 nm and 189 nm are entered, an error message is displayed in the Audit Trail. The message is displayed only at the running time, not during the Ready Check.
