Please see product details below and feel free to ask any questions. Thanks for looking! 101885 Quatech QSC-200/300 PCI serial boards utilize a single PCI slot to provide 2, 4, or 8 independent asynchronous serial ports that share a single interrupt. All PCI registers are properly implemented, so you can be assured that Quatech boards will be good citizens on the PCI bus. The board implements 16750 UARTs containing 64-byte FIFOs. Using a clock multiplying feature the QSC-200/300 is allowed to achieve data rates up to 921.6 kbps. The RS-422/485 serial boards are available with either 2 or 4-ports. The ports are jumper configurable for either RS-422 or RS-485 in any combination for full and half duplex networks. PCI registers are properly implemented to assure that Plug-and-Play works reliably, and that the board will not cause PCI bus conflicts.
