4. Functionality
The PCard-E2041L-SI-D4 functions as a multi-port serial communication interface card that enables a host computer to communicate with multiple RS-422 or RS-485 devices simultaneously. Each of the four ports can be configured independently for RS-422 or RS-485 operation, supporting both full-duplex and half-duplex communication modes.
How It Works:
When installed in a PCIe slot, the card enumerates as four independent serial COM ports in the operating system. Each port can be assigned to a specific device or communication channel. The onboard isolation circuitry ensures that electrical disturbances on one port do not affect the host system or other ports. The surge and ESD protection layers further enhance reliability by preventing damage from transient voltages or static discharges.
