FEATURES- Quartet Serial 550 PCI
       Four-port 16550 Serial I/O Board with 4-port (DB9) fan-out cable.
       Supports 32-/64-bit, 3.3V/5V PCI and PCI-X slots.
       Four high-speed 16550 UART serial ports (9-pin) support data rate 
        up to 230 Kbps.
* Will work as standard RS232 port or with 5V or 12V power output for
  devices that require power (such as handheld scanners, table scanners, 
  POS displays, etc.). Configurable via jumpers with silk-screened 
  settings on PCB.
* IRQ sharing reduces IRQ conflicts 
* Built-in 32-byte FIFO buffers dramatically increase data transmit/receive 
  speed, especially under Windows multitasking environment.
* 4-layer PCB board: separate layers for data & grounding. Greatly reduces 
  signal noise & loss. Delivers more reliable high-speed data transfers.
* Enhanced bracket design to prevent bending. Connected to PCB with 
  washered screws for a more secure connection.
* Supports 3.3V operation with 5V tolerance 
* Conforms to PCI v2.2 universal card standard. PCI-X & 64-bit compatible.
* Supports PME # (Power Management Event). Allows device to request a 
  change in system power state (wake up system).
* 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 performance/
  reliability.
* Use SMT (Surface Mount Technology) type crystal. Offers cleaner design 
  than traditional DIP-type crystal. Provides greatly improved grounding, 
  which reduces EMI emission & improves performance/reliability.
