The CyberSerial 2S PCI serial card is a compact expansion card designed for desktop computers that require additional serial ports. It provides two RS232 serial ports through a single PCI slot, making it ideal for users who need to connect legacy devices such as modems, industrial equipment, or specialized peripherals. The card is built with reliability in mind, ensuring stable performance in environments where serial communication is essential. Its design focuses on delivering a balance between cost and functionality without compromising on quality.

This card is particularly useful for professionals working in fields like engineering, manufacturing, or IT support, where older hardware still relies on serial connections. The dual-port configuration allows for simultaneous use of two serial devices, which can be crucial for tasks such as data logging or device monitoring. The card supports standard PCI bus architecture, ensuring compatibility with most desktop motherboards that have available PCI slots. It does not require any special drivers beyond standard operating system support.

Installation is straightforward, requiring only a free PCI slot and basic screwdriver tools. The card comes with no additional accessories beyond the hardware itself, so users may need to source their own mounting brackets or screws if necessary. It is important to ensure that the computer case has a compatible PCI slot and that the system's power supply can handle the additional load, although this is generally not an issue with modern systems.

The CyberSerial 2S PCI card is not suitable for newer systems that rely solely on USB or other modern interfaces. It lacks support for newer standards like USB-C or Thunderbolt, which limits its use to older or specialized hardware. However, for those who still need RS232 connectivity, it remains a reliable and cost-effective solution.
