RS-232 is a mature point-to-point protocol for serial communication. Use the RS-232 blocks to communicate with other devices by using the serial ports built into the target computer. You can also use the blocks to connect to dedicated boards that are compatible with PCI-standard bus architectures, such as PCI, PXI®, and PC/104.
You can configure the blocks to support the following boards:
Serial ports on the target computer mainboard
Third-party Quatech® PCI boards manufactured by
B&B Electronics (
Third-party Commtech PCI boards (
For detailed information about these boards, see the manufacturer documentation.
