TTL low = 0.0
Enter numbers between 1 and 8 to select the digital input lines used with this port. 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 for one port, enter
Number the lines beginning with 1 even if this board manufacturer starts numbering the lines with 0.
(PCI-6025E 8255) From the list, choose either
C. The I/O board has an 82C55A chip with 3 ports.
The port name defines which port of the 82C55A chip is used for this
driver block. Each port has a maximum of 8 digital lines that can
be configured as inputs. The PCI-6025E provides 8 digital input lines,
the PCI-6025E 8255 provides an additional 24 digital input lines,
distributed across the ports A, B, and C. In each case, one block
is required for each port.
Enter the base sample time or a multiple of the base sample
-1 means sample time is inherited).
If only one board of this type is in the target computer, enter
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
