TTL

Double

TTL low = 0.0
TTL high = 1.0

Block Parameters

Channel vector

Enter numbers between 1 and 8 to select the digital input lines used with this block. This driver allows the selection of individual digital input lines in arbitrary order. The number of elements defines the number of digital lines used.

For example, to use all of the digital inputs with this block, enter

[1,2,3,4,5,6,7,8]

Each line can be used for input or output. If a line is not listed in this field, a digital output block using the same board can use that line.

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

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')
