Block Parameters

Channel vector

Enter a vector of numbers to specify the input channels. For example, to use the first three analog input (A/D) channels, enter

[1, 2, 3]

The channel numbers can occur in arbitrary order. Number them beginning with 1 even if this board manufacturer numbers them beginning with 0.

The maximum allowable channel number for this board is 32 (differential-ended) or 64 (single-ended). If the highest channel number you specify is n, the I/O module will convert all the channels between 1 and n, whether or not they occur in your channel vector. It is more efficient to specify a contiguous range of channels. (Permuting the order of such a range has little impact on efficiency however.)

Range vector

This board allows the range of each channel to be selected independently. If you enter a scalar, the value is replicated over the channel vector. If you enter a vector, it must be the same length as the channel vector.

The range vector entries must be range codes selected from the following table:

Input Range (V)

Range Code

Input Range (V)

Range Code

-10 to +10


0 to 10


-5 to +5


0 to 5


-2.5 to 2.5


0 to 2.5


-1.25 to 1.25


0 to 1.25



Choose single-ended or double-ended (differential-ended). This value is replicated over the channel vector.

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')
