Getting Started

The following section shows the NuDAQ Topic Definition dialog box and

gives the detailed description of each field:

Topic Name: This field is used to enter a Topic Name. (The same DDE

Topic Name is entered in the InTouch "DDE Access Name

definition" dialog box described in the section 3.1). The topic

must be a unique name that is matched by the DDE clients

(for example InTouch). Topic Name can be up to 32

characters long.

Card Type#BoardNumber: Associate the topic with a NuDAQ board

(additional topics may be associated with this same board at

a later time).

AI Range: The data range setting of analog input for the NuDAQ board

configured. The field is only available for the boards support AI

(PCI-9111 DG/HR, PCI-9112, PCI-9113, PCI9114 DG/HG and

PCI-9118DG/HG/HR).

AI Mode: The analog input mode (Single Ended or Differential mode) for

the NuDAQ board configured. The field is only available for the

boards that support both the two modes (PCI-9112,

PCI9114DG/HG and PCI-9118DG/HG/HR). The default AI

mode is Single Ended mode.

Update Interval: This field tells the server how often it will try to poll the

data from the board associated to the topic defined. The

valid range of Update Interval is from 1 to 65535 and

the default value is 1000(msec).
