Keep legacy serial infrastructure in service without adding external adapters or extra cabling. The Advantech PCIE-1622B-BE provides 8 ports of RS-232, RS-422, and RS-485 connectivity through a PCI Express expansion card, giving systems integrators a compact way to connect multiple serial devices from one host platform. This card is built for environments where serial communication still matters: factory equipment, instrumentation, control systems, and embedded PCs that need dependable port density. Integrated surge protection adds a practical layer of resilience for installations exposed to electrical noise and transient events. That matters when the cost of a dropped serial link is measured in downtime, not inconvenience. For teams standardizing on PCIe-based hosts, the PCIE-1622B-BE reduces the need for external multiport converters and keeps the installation inside the chassis. The result is cleaner deployment, fewer failure points, and a more controlled path for supporting mixed serial protocols on a single platform.
