Quatech QSC-200/300 Internal Serial interface cards/adapter

4 x DB-9, RS-422/485, 921.6 kbps, PCI 2.1 32bit, 33MHz, 5V, 260mA <b>4 port RS-422/485 PCI board with DB-9 cable</b>

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.
