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 starts numbering the lines 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).

Base address

Enter the base address of the board. This entry must correspond to the DIP switch setting on the board. For example, if the DIP switch setting is 300 (hexadecimal), enter 0x300.
