Diamond Prometheus/Athena/Athena II Digital Input

Prometheus/Athena Digital Input block (not recommended)


Simulink® Real-Time™ Library of Drivers No Longer Recommended for Use


Prometheus and Athena boards have three I/O ports, each containing eight digital I/O lines. You can independently configure these ports 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.

Block Parameters

Channel Vector

Enter a vector of numbers between 1 and 8 to select the digital input lines used from 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 the current port, enter


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


From the list, choose A, B, or C to choose one of the three I/O ports.

Sample time

Enter the base sample time or a multiple of the base sample time (-1 means sample time is inherited).

Base address

Enter the base address of the board. This entry must correspond to the DIP switch setting on the board. For example, if the DIP switch setting is 300 (hexadecimal), enter 0x300.
