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.
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.
The Commtech/Fastcom and Quatech 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/products.
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
[BusNumber,SlotNumber]. 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.
