RS-232/422/485 Board Setup (Commtech) and Interrupt Check (Quatech) block
Simulink® Real-Time™ Library for RS-232
(Quatech® and Commtech only) The Board Setup and Interrupt Check block checks for instances where the IRQ differs from the software for which it is listening.
Note: The Diamond Systems PC/104 boards and blocks will be removed in a future release. Do not use them in new models. Instead, use boards and blocks available from www.speedgoat.com.
This block compares the software-selected interrupt against the value for which the board (PCI only) is configured. This check prevents IRQ mismatches. For the Commtech Fastcom® board, the corresponding block also sets up the board clock.
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
To determine the bus number and the PCI slot number, type:
tg = slrt; getPCIInfo(tg, 'installed')
Enter the number of clock bits to control a clock generator common to both channels. This parameter adjusts the master clock of both channels.
From the list, select an IRQ line number from 5 to 15, inclusive.
