Installing and Controlling Third-Party Devices
Nelson Interfaces: Device Driver Configuration
In the default configuration (set only the COM port, use all other settings), the device driver supplies all functions for a non-controlled timebase. The Remote Inject and the Integrator are virtually integrated. Installing a serial autosampler or detector device driver is also possible. In this case, disable the included device drivers to clear the corresponding ports for the other device drivers.
Integrated "Remote Inject"
The integrated Remote Inject device driver is configured on the Remote Inject tab page.
If Read Sample Position from Rack & Vial Port is selected, the sample position is read from the port (RVP) immediately after injection. The following options are available:
Select Invert Inputs if the meaning of True and False is inverted; for example, if position 1 is read as 4094 (= 3FFEh).
Mask should only be changed if further signals not related to the autosampler position are connected to the RVP. (This is a Hex number that is linked via and to the value read by the RVP.)
Set Encoding to binary if the autosampler performs binary coding of the autosampler position (This is not common, otherwise position 16 is read as 10.)
Using a Different Autosampler Device Driver
If a different autosampler device driver is used, the integrated Remote Inject driver should be disabled. In this case, the start input of the box is available as RemoteStart port for other drivers using a digital Inject Response. This port should then be used instead of an A/D card input. The Inject command of the autosampler enables the ready line of the box, as with the integrated Remote Inject.
For device drivers using a serial Inject Response (no Inject Response port can be set here - this applies to most autosampler device drivers), the Inject command of the autosampler does not enable the ready line.
Using a different Detector Device Driver
If a different detector device driver should be used for one or both channels, the integrated channel must be disabled (Signals tab page). The Nelson driver supplies the channel as the port Channel_A or Channnel_B. For the detector driver, this port can be used instead of an AD card port.
