Interface Card EXSYS EX-42042IS

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.

How to use

To install the card, power down the computer, disconnect it from the mains, and open the system casing. Insert the interface card firmly into an available PCI slot and secure the bracket to the computer chassis. Close the case, reconnect the power, and start the system. The operating system will automatically detect the hardware due to Plug-and-Play support. Connect your serial cables to the 9-pin D-SUB ports and configure the transmission output settings for each port according to your connected device requirements.

What to consider before purchase

• Verify that your computer motherboard has a compatible physical PCI or PCI-X expansion slot available.
• Check that your operating system is compatible with the card and supports the required drivers.
• Confirm the communication protocol requirements of your external serial devices to ensure compatibility with RS-232, RS-422, or RS-485.

Usage recommendations

Ensure proper electrostatic discharge precautions are taken during installation. Regularly check firmware and driver updates to maintain optimal performance and compatibility with your operating system.
