Flat serial, native RS232 PCI Express card with 1 port and 16550 UART. The serial PCI Express card PEX1S553LP converts a PCI Express slot into an RS232 interface (DB9). The serial card is based on a native single-chip design that fully utilizes the capacity of PCI Express (PCIe) and reduces the load on the CPU by up to 48% compared to conventional serial cards. A high-speed serial RS232 port with a data transfer rate of up to 460.8 kbit/s is provided with a half-height/flat mounting bracket, including a standard bracket. Selectable output power on pin 9 for the serial connection. Compliant with the base specifications for PCI Express, Revision 1.1a. Automated out-of-band flow control using CT/RTS and DSR/DTR. Automated in-band software flow control using programmable Xon/Xoff in both directions. 128-byte deep FIFO per transmitter and receiver. The PCI Express RS232 serial adapter card is compatible with a variety of operating systems, including Windows 2000/XP/2003/Vista/Windows 7/Server 2008 R2 (32 and 64 bit) as well as Linux Kernel 2.6.11 and higher. Applications: Self-service kiosks and vending machines, bank counter workstations in high or low profiles, POS retail applications in grocery stores, standard ATM cash machines, used to control multiple surveillance and security cameras.
