Quattro-PCI Powered (PCI 4 port RS-232 Powered)


PCI Bus 16550 Four Port Serial Board

The Quattro-PCI Powered offers an efficient way to utilize PCI slots and system resources while eliminating external cabling and power bricks. The Quattro-PCI Powered adds four 5/12 volt powered serial ports, while using only one system IRQ.

The Quattro-PCI Powered’s four 16550 UART serial ports enable high-speed transfer rates and are ideal for connecting peripherals such as barcode scanners or debit/credit card readers that can draw power on their serial connectors. The Quattro-PCI Powered provides 12 VDC on serial pin 1, and 5 VDC on serial pin 9. The Quattro-PCI Powered can simplify Point-of-Sale (POS) or other installations by eliminating unnecessary power bricks and cabling, and can increase system reliability through reducing the need for separate power supplies for each peripheral.

The Quattro-PCI Powered’s economical use of PCI real estate, IRQs, and COM port resources make it an excellent expansion option for POS system builders!
