4. Functionality
The PCard-E2021L-SI-D5 functions as a dual-channel serial communication interface card that allows a host computer to communicate with RS-422 or RS-485 devices through the PCI Express bus. Each port 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 a standard serial communication device. The onboard controller manages data transmission and reception through the two serial ports, utilizing the 128-byte FIFO buffer to ensure smooth data flow even at high baud rates. The galvanic isolation barrier separates the host system from the field devices, protecting against voltage spikes, ground potential differences, and electrical noise.
