SIIG’s CyberSerial Dual PCI is designed to provide you with two additional 9-pin (DB9) RS-232 serial ports to your desktop computer for more serial-based device connections. This 2-port serial adapter card comes with two high-speed 16550 UART serial ports supporting data transfer rates of up to 230Kb/s. The serial ports can work as either standard RS-232 ports, or with 5V/12V power outputs for devices that require power such as handheld scanners, table scanners, and POS displays. Additional features include IRQ sharing to reduce IRQ conflicts, built-in 32-byte FIFO buffers to dramatically increase data transmit/receive speed especially under Windows multitasking environment, and PME (Power Management Event) that allows device to request a change in system power state (wake up system).
