RS-232 is a mature standard for serial communication. To model an RS-232 network by using the serial ports on the target computer, use the RS-232 protocol blocks. The blocks connect to boards that are compatible with PCI-standard bus architectures, such as PCI, PXI®, and PC/104.
With block parameters, you can configure the blocks to support the following boards:
Quatech® PCI boards manufactured by B&B Electronics
Commtech PCI boards (
Diamond Systems PC/104 boards (
For detailed information about these boards, see the manufacturer documentation.
