ExpressCard slots are scaleable high speed bus interfaces that improve performance by supporting both the PCI Express and USB 2.0 standards in a single slot. However many Expresscard Serial and Parrallel port cards make use of the USB 2.0 interface and are not compatible with some applications.
Quatech’s new ExpressCard Performance Series provides enhanced serial and parallel ports that are connected directly to the host systems PCI-Express bus and as a consequence out perform similar USB controller based devices. The Express Card Adaptors support a single PCI-Express lane operating at up to 2.5 Gbps data rate. In Addition a PCI-Express based design can directly use I/O address space and interrupts, thus more closely emulating traditional built-in ports than can be done via USB-based design.
Available models include the SPPXP-100 parallel port card, the SSPXP-100 and DSPXP-100 one and two port RS-232 serial cards, and the SSPXP-200/300 and DSPXP-200/300 one and two port RS-422/485 cards. The Express Card Adaptor supports data rate speeds of up 921.6kbps, offering a steady data throughput. The serial design offers flexibility with deeper FIFOs, auto half-duplexing transmit control on RS-422/485 cards and full compatibility with all Windows COM port settings. The parallel port SPPXP-100 supports both ECP and EPP modes and uses the standard Windows parallel port driver for unbeatable compatibility. While the Quatech parallel and serial ExpressCards are I/O addressable, legacy DOS addresses are not supported.
All Quatech Express Card Adaptors are RoHS compliant; support Windows® 2000, XP, Server 2003 and Vista platforms.
