PCI Express Serial Cards

Expand any Windows or Linux PC with reliable, industrial-grade serial connectivity using our SystemBase PCI Express Serial Communication Cards. Each low-profile PCIe card adds 8 independent RS232 ports directly to your system, powered by SystemBase's SB16C1058PCI UART with a 256-byte FIFO buffer — the largest in its class — to eliminate data overruns even at speeds up to 921.6kbps.

Built-in ±15kV surge protection and slew-rate limit control make these cards a dependable choice for POS systems, factory and building automation, and medical equipment. Choose the DB9 Male model for direct device connections, or the DB9 Female model with its rugged aluminum connector panel and LED port-status indicators for panel-mount installations.
