6-Port PCI-Express Serial Card SD-PEX15023 from Best Connectivity

This is a 6-port PCI-Express serial card designed for computers that require multiple serial communication ports. It is ideal for industrial, embedded, or specialized computing environments where legacy devices or equipment still rely on serial connections. The card uses a MCS9901 chipset and is built to the PCI-Express Base Specification Revision 1.0a standard, ensuring compatibility with a wide range of motherboards and systems that support PCI-Express slots. It provides a single-lane (x1) connection with a maximum throughput of 2.5 Gbps, making it suitable for high-speed data transfer applications.

The card includes built-in 16C550 compatible UARTs, which are commonly used in serial communication systems for reliable data transmission. It features a 256-byte deep transmit and receive FIFO buffer, which helps reduce data loss and improves overall performance during high-speed transfers. The card supports RS-232 hardware and software flow control, allowing for efficient communication with devices that use these standards. This makes it particularly useful in environments where data integrity and timing are critical.

An octopus cable is included with the card, which allows for easy connection to multiple serial devices without the need for additional adapters or cables. The card is designed to be installed in a PCI-Express slot on the motherboard, and it requires minimal setup once installed. It is well-suited for use in environments such as manufacturing, telecommunications, or data centers where multiple serial devices need to be connected simultaneously.

The card's transfer rate is up to 250 Kbps, which is sufficient for most serial communication applications but may not be suitable for high-bandwidth requirements. It does not support newer serial standards beyond RS-232, so it may not be compatible with devices that use USB or other modern interfaces. Users should ensure their system has a free PCI-Express slot and that their operating system supports the necessary drivers for the MCS9901 chipset.
