The Startech PCI Serial Card 2S232422485-PC-CARD is a professional solution designed to add two DB9 serial ports with configurable support for RS-232, RS-422, and RS-485 standards to any desktop or small form factor system via a PCI Express x1 interface. These ports can be independently configured using built-in DIP switches, allowing adaptation to multiple peripheral devices and serial communication protocols, including 2- or 4-wire RS-485 options, widely used in industrial and automation environments. The card features LED indicators for real-time monitoring of each port’s activity, enhancing safety and control during use. It also includes configurable external power via SATA, allowing selection between 12 V (1.5 A per port), 5 V (1.5 A per port), or no power (RI) modes, optimizing power compatibility based on the connected device. Compatible with Linux and Windows operating systems (including Windows 7, 8.1, 10, 11, and Server versions 2016, 2019, and 2022), it ensures easy integration in mixed environments. With compact dimensions of 102 mm width, 105 mm depth, and 16 mm height and a black design, this PCIe 2.0 expansion card incorporates an ASIX AX99100 IC with a 16C1050 UART and a maximum data rate of 921.6 Kbit/s, plus a 256-byte PEPS buffer for efficient data handling. The card is aimed at maintaining functionality of equipment with serial interfaces, avoiding costly hardware replacements in applications such as point-of-sale terminals, programmable logic controllers (PLCs), scientific sensors, medical devices, scanners, and oscilloscopes. Its construction includes ESD level 4 protection, ensuring durability against electrostatic interference, crucial in industrial and laboratory settings. In summary, this Startech PCIe serial card offers a robust and versatile option to upgrade legacy systems with reliable technology and a high degree of serial communication customization.
