Product Description
The StarTech PCI4S550N is a PCI adapter card that significantly expands a computer's serial communication capabilities by providing four RS-232 serial ports. This makes it an excellent choice for environments that require connecting multiple serial devices simultaneously, such as industrial control systems, laboratory equipment, retail POS systems, or network management setups. The card utilizes the widely adopted 16550 UART (Universal Asynchronous Receiver/Transmitter) chip. The 16550 UART is known for its reliability and its built-in FIFO (First-In, First-Out) buffer, which helps to manage data flow efficiently and reduce the risk of data loss, particularly when dealing with moderate to high serial communication traffic. Each of the four ports uses standard DB9 connectors, ensuring broad compatibility with a vast array of serial peripherals and cables. The card supports standard RS-232 signaling and can achieve data transfer rates of up to 115.2 Kbps, which is sufficient for most serial device applications. Installation is designed to be user-friendly with plug-and-play support, allowing for quick integration into systems with available PCI slots.
