Quatech/B&B Performance PCIe based RS-232 Serial ExpressCards
Quatech/B&B's high performance ExpressCard 34 to Serial I/O cards adds fast serial COM ports to mobile computers for attaching fax/modems, bar code scanners, court reporters, data acquisition equipment, mag stripe readers, GPS receivers, digital cameras or other RS-232 serial devices. Unlike other ExpressCard Serial adapters, Quatech/B&B's utilize the PCIe portion of the ExpressCard standard.
Advantages of a PCIe-based ExpressCard design are in the interface to the laptop's motherboard. The PCIe bus interface is the successor to the PCI bus, which in turn was the successor to the ISA bus to which built-in ports were originally attached. As such, the ExpressCard adapter design utilizes a PCIe-based design and can still directly use I/O space addresses and interrupts, thus more closely emulating built-in ports than can be done via USB-based design. Moreover, because there's no USB stack for the drivers to contend with, throughput can be higher and latency will be lower (considerably so in many cases). Due to improved data transfer rate, the ExpressCard is considerably more efficient for multi-tasking operations. The PXPseries support data rates of up to 921.6Kbps, which provides steady flow of data throughput.
