SIIG's CyberSerial 4S 550 PCI serial adapter card is an excellent solution for you to connect multiple serial-based devices to your system. It is designed to add four 9-pin serial ports to your PCI-enabled desktop computer. This 4-port serial adapter card comes with four high-speed 16550 UART serial ports supporting data transfer rates up to 230 Kbps. The serial ports can work as either standard DB9 RS232 ports, or can be configured with 5 V/12 V power outputs for devices that require power such as handheld scanners, table scanners, and POS displays. The CyberSerial 4S 550 PCI adapter card features 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) to allow device to request a change in system power state (wake up system). Industry standards met by this Oxford OXuPCI954 powered serial adapter card include PCI v2.2 universal card standard, PCI-X and 64-bit compatible, RoHS, and FCC Class B (DoC) and CE regulatory approved.
4-layer PCB board - separate layers for data and grounding
It greatly reduces signal noise and loss; delivers more reliable high-speed data transfers.
Conforms to PCI v2.2 universal card standard
It allows device to request a change in system power state (wake up system).
Use SMT (Surface Mount Technology) type electrolytic capacitor
With low ESR (Equivalent Series Resistance) aluminum electrolytic capacitor, it offers much improved noise suppression and achieves higher levels of performance/reliability.
Use SMT (Surface Mount Technology) type crystalProduct Highlights
It offers cleaner design than traditional DIP-type crystal. It provides greatly improved grounding, which reduces EMI emission and improves performance/reliability.
