Frequently Asked Questions
What is the primary difference between the PEX2S952 and the newer PEX2S953? +
The PEX2S952 is a legacy adapter that has been officially discontinued by StarTech.com and replaced by the PEX2S953. The PEX2S953 serves as the current iteration, maintaining the same native PCI Express architecture and dual RS232 serial port functionality, while ensuring better compatibility with modern motherboard chipsets and operating systems compared to the older PEX2S952 model.
Does the PEX2S952 utilize a native PCI Express single-chip design? +
Yes, this adapter card features a native PCI Express single-chip design. By avoiding the use of a bridge chip to convert from PCI to PCIe, this card offers enhanced reliability, lower latency, and reduced CPU load, making it a preferred choice for high-speed serial communication in industrial and server environments where consistent data throughput is critical.
What type of UART does this serial adapter card incorporate? +
The PEX2S952 is equipped with the high-performance 16950 UART. This advanced UART supports a larger 128-byte deep FIFO buffer, which significantly improves data reliability and performance during high-speed serial transfers. It is particularly effective in environments where multitasking could otherwise lead to data loss or buffer overflows on older, standard 16550 UART interfaces.
Will the PEX2S952 fit into a small form factor server chassis? +
This adapter card includes a low-profile bracket in the package, making it highly versatile for various deployment scenarios. Whether you are using a standard ATX tower or a compact 2U server chassis, the card can be easily adapted to fit, ensuring you have the necessary serial connectivity regardless of your specific hardware footprint.
Can I use the PEX2S952 for industrial serial device automation? +
Absolutely. The robust design and reliable UART performance make this card an excellent solution for connecting serial peripherals such as barcode scanners, industrial sensors, PLC controllers, and POS systems. Its native PCIe connection ensures that your automated processes remain stable and responsive even under heavy communication loads or during intensive data polling tasks.
Is the PEX2S952 compatible with older legacy operating systems? +
The card is designed to support a wide range of operating systems, though its specific driver compatibility will depend on the OS environment. Because it uses a standard 16950 UART interface, it is highly recognizable by most Windows and Linux distributions. For older systems, you should verify that your specific kernel version has the necessary serial controller support installed.
What is the maximum baud rate supported by this 2-port serial card? +
The PEX2S952 supports high-speed data transfer rates up to 460.8 Kbps per port. This capacity makes it suitable for demanding serial applications that require fast communication speeds, providing a significant performance advantage over standard motherboard serial headers or inferior USB-to-serial converters that may struggle with timing-sensitive serial protocols.
Does this card require additional power connections from the PC power supply? +
The card is powered directly through the PCI Express bus slot, so it does not require additional cabling or power headers from your computer's power supply unit. This streamlined design simplifies cable management inside your server and reduces the risk of power interference, allowing for a cleaner and more professional internal installation.
How can I obtain a volume price quote for this StarTech.com serial card? +
