SUNIX UNIVERSAL PCI DUAL RS-232 SERIAL COMMUNICATION BOARD PCI Serial Card

SUNIX SER5037A Universal PCI Serial Communication Board adds two RS-232 ports to a desktop PC via a standard Universal PCI slot, delivering native serial connectivity in a compact expansion card. Built around a SUNIX UART controller (UL7512EQ) and part of the GoldenIO card series, this dual-port RS-232 card provides two independent RS-232 channels for reliable data exchange with serial devices. The universal PCI interface expands a PC’s serial I/O without consuming PCIe lanes, making it a practical upgrade for older systems or embedded PCs that still rely on RS-232. Typical applications include connecting legacy peripherals and industrial equipment that communicate over RS-232, such as data loggers, CNC interfaces, or bar code scanners. With two ports on a single card, you gain parallel serial access for multiple devices while keeping the motherboard layout uncluttered.
