Quatech DS-PCI-100 Internal Serial interface cards/adapter

DS-PCI-100, 1 PC slot to 2 RS-232 ports Quatech RS-232 PCI boards utilize a single PCI slot to provide two, four, or eight 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 RS-422/485 serial boards are available with either two or four 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.
