StarTech.com 3 Port PCIe LPT RS232 Serial Card

StarTech.com PEX2S5531P 3 Port PCIe LPT RS232 Serial Card transforms a PCI Express slot into two RS232 serial ports and one parallel port, delivering enhanced communication capabilities for diverse computing environments. Featuring a native single-chip PCI Express design, it offers improved speed, greater reliability, and reduced CPU load compared to traditional serial cards with bridge chip designs.

This Serial Card supports a maximum baud rate of 460.8 Kbps on the RS232 ports and 1.5 Mbps on the parallel port, enabling efficient handling of serial and parallel communication tasks. Equipped with 128-byte deep FIFO buffers for both transmitter and receiver, it ensures smooth data flow and minimal bottlenecks.

Designed for broad compatibility, the card supports operating systems such as Windows (2000 through Windows 7 and Server 2008 R2, 32/64-bit), Linux kernel 2.6.11 and later, and Mac OS 10.4. Its PCI Express slot interface is single-lane and native, fully leveraging PCIe performance for optimized throughput.

The card includes selectable power options on pin 9 of the serial ports and configurable modes for 5V, 12V, and RI (non-powered) operation. Automated out-of-band flow control (CTS/RTS, DSR/DTR) and in-band flow control (Xon/Xoff) in both directions enhance communication stability and control.

Installation flexibility is provided by the inclusion of both standard and low-profile half-height brackets, ensuring compatibility with virtually any computer case form factor. This device is a replacement for the PEX2S5521P model, and benefits from StarTech.com's lifetime warranty and lifetime technical support.

Typical applications include automotive kiosks, POS retail systems, bank teller stations, ATMs, surveillance camera control, and other industrial and commercial environments requiring robust serial and parallel connectivity.

Features two RS232 serial ports with data rates up to 460.8 Kbps. Includes one parallel (LPT) port supporting data transfer rates up to 1.5 Mbps. Supports PCI Express base specification revision 1.0a with native single-chip, single-lane PCI Express chipset.

128-byte FIFO buffers for efficient data transmission and reception. Configurable power output on serial ports including 5V, 12V, and non-powered modes. Automated out-of-band and in-band flow control mechanisms for reliable data communication.
