Manual Configuration for COM Ports
The PCIe multiport serial card supports 2/4/8 RS-232 or RS-422/485 serial ports. Depending on
the operating system, COM port mapping may be applied automatically during the hardware

your needs, you can change the COM Port mappings manually. In this section, we will take PCIe-
S148 as an example to show you the steps of manual configuration.
