## Long description

The Exsys EX-42042IS is a reliable PCI interface card equipped with the Oxford OXPCI952 chipset, designed to expand system connectivity with high-performance serial ports. Operating on standard DC power supply voltages of 3.3V and 5V, this I/O adapter features two 9-pin D-SUB serial ports and a 4-pin plug, providing robust compatibility and stable data transmission. Built with integrated optical isolation and surge protection, it safeguards connected devices against electrical interference and power spikes. Its compact physical dimensions of 120 mm in width and 80 mm in depth, combined with a sturdy build weighing 500 grams, make it a dependable component for various industrial and professional computing environments.
Advantages
This PCI interface card stands out by offering versatile serial port support, allowing individual selection of transmission outputs including RS-232, RS-422, and RS-485 for each port. The inclusion of 16C950-type UART ensures high data throughput and reliable communication performance. Furthermore, optical isolation and surge protection enhance system safety in electrically demanding environments, while full Plug-and-Play compatibility ensures straightforward installation without complex configuration steps.
Suitable for
Expanding COM ports on desktop PCs, thin clients, and servers
Industrial automation and control systems requiring RS-422 or RS-485 communication
Legacy hardware integration needing RS-232 serial connectivity
Environments requiring galvanic isolation and surge protection for serial lines
When it may not be suitable
This interface card is not suitable for modern computer motherboards that lack standard PCI or PCI-X expansion slots, as it requires a physical PCI slot to function. Additionally, it will not meet the needs of users seeking consumer-grade peripheral connections such as USB or HDMI, as it is strictly designed for serial communication tasks.
