Dionex Open Autosampler OAS-3x00TXRS

Specify the general device or hardware parameters, such as, device name, communication and inject response signal settings.

Option

Description

 

 

Device Name

Indicates the name under which the instrument is identified in the installation environment (default: Sampler; also, refer to Naming Devices ...). To control the instrument via the existing Control Panels, accept the default name. If you do not accept the default name, you may have to edit the PGM Files and re-link the corresponding control of the control panel. (Also, refer to Linking a Control to a Device.)

 

 

Instrument Data Location

Specify the location where the instrument method templates are stored. The path for the default instrument method templates provided by Thermo Fisher Scientific is C:\Thermo\Data Files\Chromeleon\Drivers\UltiMate Open Autosampler.

 

 

Communication Port

Select whether communication between the Chromeleon Server PC and the autosampler is performed via TCP/IP (recommended) or a COM port.

  • If the autosampler is connected via Ethernet, select TCP/IP and enter the appropriate host name or IP address in the Host Name or IP Address box. The IP address can be read from the autosampler's control terminal. For information about how to setup the TCP/IP connection, also refer to Connect Modules via TCP/IP (LAN) and the related subtopics.

    Note:

    By default, the autosampler is shipped with the Communication Port set to TCP/IP and a predefined IP address. If you change the communication settings, the autosampler should be powered OFF and ON again to allow the changes to take effect. Also refer to UltiMate 3000 Series OAS-3x00TXRS: Installation, section Device Connection for information.

  • If the autosampler is controlled by Chromeleon via a COM port (serial communication), select the number of the COM port on the Chromeleon Server PC used for connecting the autosampler.

 

 

Signal received via

Specify how the Inject Response signal is transmitted between the autosampler and the pump. Click the arrow in the Signal received via box to select one of the following options:

  • Input port – Use this setting when operating the autosampler with a UltiMate 3000 RS (not XRS), SD or BM pump. Synchronization of the inject response signal is controlled by the hardware using a signal synchronization cable (Dionex part no. 6043.0001). Click the arrow in the Inject Response Input Port box to select the input port to which the signal synchronization cable is connected. For details, refer to UltiMate 3000 Series OAS-3x00TXRS: Installation. (Also see Inject Response Input Port below.)

  • Serial port – Use this setting when operating an LPG-3400XRS pump or a pump of a third-party manufacturer. Synchronization of the inject response signal is controlled by the PC using a RS-232 synchronization cable (Dionex part no. 6043.0002). Click the arrow next to the Inject Response Serial Port box to select the COM port to which the cable is connected (also see Inject Response Serial Port below).

    Note:

    The COM port selected here must not be identical to the serial COM port that is selected in the Communication Port box.

 

 

Inject Response Input Port

(Only available if Signal received via is set to Input port.)

Select the digital input port that is used to connect the autosampler to the pump via the signal synchronization cable.

Before you can select the input, you first have to enable the digital input on the configuration page of the pump: On the Input tab page of the pump, select the check box of the input port that is connected with the signal synchronization cable, for example, Pump_Input_2 for a DGP-3000RS, SD or BM pump. Also see Signal received via above.

 

 

Inject Response Serial Port

(Only available if Signal received via is set to Serial port.)

Select the COM port (RS-232 port) to which the RS-232 synchronization cable (Dionex part no. 6043.0002) is connected on the Chromeleon PC. Also refer to option Signal received via above.

 

 

Pump Link (LPG only)

If the system includes a pump capable of stroke synchronization (for example, a UltiMate 3000 RS, SD or BM pump), the injection command can be synchronized with the pump strokes. Synchronization ensures that all injections are performed at the same phase of the pump cycle; this enhances the retention time precision for gradient applications.

Select the pump unit that is used for synchronizing the pump stroke, for example:

UM3PUMP_STRK for an LPG-3400 (RS, SD, or BM)

UM3PUMP_L_STRK (for the left pump of a DGP-3600) or UM3PUMP_R_STRK (for the right pump of a DGP-3600).

Select None, if the pump does not support pump stroke synchronization or if synchronization is not required.

Also select None when you are using an LPG-3400XRS pump.

Note:

In addition to defining the Pump Link (LPG only) setting in the Chromeleon Server Configuration you must also specify the synchronization signal on the keypad of the autosampler. Otherwise, pump stroke synchronization will not be enabled. For details on how to define the settings on the autosampler's keypad, refer to:

UltiMate 3000 Series OAS-3x00TXRS Autosampler: Installation.
