DT2828 series boards have two I/O ports, each containing 8 digital I/O lines. These ports can be configured independently for either input or output. Use a separate driver block for each port. By selecting the digital input driver block for a given port, that port is configured for input.

Driver Block Parameters
Port -- From the list, choose 1 or 2.
Channel vector -- Enter numbers between 1 and 8 to select the digital input lines you use with this port. This driver allows the selection of individual digital input lines in any order. The number of elements defines the number of digital lines you use.
For example, to use all of the digital inputs for this port, enter
Number the lines beginning with 1 even if the board manufacturer starts numbering the lines with 0.
