Frequently Asked Questions
What is an 8-port RS-232/422/485 communication card used for?
An 8-port serial communication card connects multiple legacy serial devices, industrial equipment, and sensors to modern computers. The PCIE-1622C-AE supports all three protocols (RS-232, RS-422, RS-485), making it ideal for SCADA systems, data acquisition, PLC connectivity, and industrial automation applications requiring reliable serial connectivity.
How does 2,500 VDC isolation protect my system?
Galvanic isolation physically separates the serial communication circuits from your computer's ground, preventing ground loop noise and protecting against voltage surges. The 2,500 VDC isolation rating ensures your system remains safe even when connected to equipment operating at significantly different electrical potentials, critical in industrial environments with multiple power sources.
Can the PCIE-1622C-AE handle high-speed industrial data transmission?
Yes. With transmission speeds up to 921.6 kbps and advanced PCIe958 UART processors featuring 128-byte FIFOs, this PCI Express serial card efficiently handles high-speed data streams while minimizing CPU load. The independent port architecture allows simultaneous multi-port operation without performance degradation.
Is this card compatible with modern PCI Express systems?
Absolutely. The PCIE-1622C-AE uses the standard PCI Express x1 interface, compatible with any modern motherboard or industrial computer with available PCIe slots. It supports both legacy and contemporary operating systems with appropriate drivers.
