SIIG IO Card JJ-P04621-S7 Dual Porfile Quartet Serial 550 PCI Brown Box
1.Regulatory approval(s): FCC Class B (DoC) CE2.RoHS compliant3.Chip: CyberPro4.Bus type: 32-bit PCI5.Port type: Four DB9 (9-pin) RS232 serial ports6.IRQ sharing reduces IRQ conflicts7.Built-in 32-byte FIFO buffers dramatically increase data transmit/receive speed under Windows multitasking environment8.4-layer PCB board: separate layers for data grounding. Significantly reduces signal noise loss and delivers reliable high-speed data transfer9.Enhanced bracket design to prevent bending. Connected to PCB with washered screws for a more secure connection10.Supports 3.3V operation with 5V tolerance11.Conforms to PCI v2.2 universal card standard. PCI-X 64-bit compatible12.Supports PME No (Power Management Event). Allows device to request a change in system power state (wake up system)13.Use SMT (Surface Mount Technology) type electrolytic capacitor. Low ESR (Equivalent Series Resistance) aluminum electrolytic capacitor. Offers much improved noise suppression achieves higher levels of
