PCI is thestandard for board level expansionslots in PC-based systems.Quatech has specialized in qualitydata communication products forover 20 years. We have a provenfailure rate of only .002% after burn-in. And, Quatech’s meticulouslydesigned boards strictly adhere tothe PCI specification, so you can restassured that our products willconsistently function properly in yoursystems.Quatech PCI boards offer extensivechoices for adding serial functionalityto a system using minimal systemresources. They also provide apeace of mind.Quatech RS-232 PCI boards utilize asingle PCI slot to provide two, four, oreight independent asynchronouss e r i a l p o r t s t h a t s h a r e asingleinterrupt. All PCI registers areproperly implemented, so you can beassured that Quatech boards will begood citizens on the PCI bus. Serialport connections are made via DB-9male connectors, DB-25 maleconnectors, or RJ-45 modularconnectors (8 port only).In addition, industrial surgesuppression may be added as anoption.The QSC-200/300 (4 port RS-422/485) and ESC-100 (8 port RS-232) boards implement 16750UARTs containing 64-byte FIFOs,while the DSC-100 (2 port RS-232),DSC-200/300 (2 port RS-422/485)and QSC-100 (4 port RS-232)achieve 16550 UARTs. They use aclock multiplying feature allowing theboards to achieve data rates as highas 921.6 kbps.To maintain maximum signalintegrity, Quatech uses a four-layerboard design. For better protection inindustrial environments, we offer asurge suppression package optionthat applies a surge suppressor toeach line that is capable of sustainingup to 40A peak, 8 x 20μs transientsurges, a clamping voltage of 30Vand a peak energy dissipation of 0.1Joules. (Note that implementing theIND option restricts the board'sspeed to 115.2 kbps.)With Quatech’s five year warrantyand our customer support teamproviding expert pre-sales, technicaland customization support -- youtruly have the industry’s most reliableserial PCI board.Multiport Serial PCI BoardsSeamless system expansion solutions for adding multiple serial ports to PC-based systems
