Block Parameters

Number of channels

If you select 16 channels (Input coupling parameter set to 16 single-ended channels) enter a number between 1 and 16 to select the number of A/D channels used. If you select eight channels (Input coupling parameter set to 8 differential channels) enter a number between 1 and 8. This driver does not allow the selection of individual channels or to mix single-ended and differential inputs.

Number the lines beginning with 1 even if this board manufacturer numbers the lines beginning with 0.

Range

From the list, choose either +-10V (-10 volts to +10 volts), +-5V, +-2.5V, +-1.25V, +-0.625V, 0-10V, 0-5V, 0-2.5V, or 0-1.25V. This driver does not allow the selection of a different range for each channel.

If a bipolar range is used, the bipolar switch on the board must be in the bipolar position. If a unipolar range is used, the bipolar switch must be in the unipolar position.

Input coupling

From the list, select one from the following list of input modes:

  • Single-ended channels (16 channels)

  • Differential channels (8 channels)

    This choice must correspond to the MUX-switch setting on the board.

Sample time

Enter the base sample time or a multiple of the base sample time (-1 means sample time is inherited).

PCI slot (-1:autosearch)

If only one board of this type is in the target computer, enter -1 to locate the board.

If two or more boards of this type are in the target computer, enter the bus number and the PCI slot number of the board associated with this driver block. Use the format [BusNumber,SlotNumber].

To determine the bus number and the PCI slot number, type:

tg = slrt;
getPCIInfo(tg, 'installed')
