MODEL- SL0751-161      VENDOR- SOCKET COMMUNICATIONS INC.

FEATURES- PCMCIA Quad Serial I/O Card- Ruggedized
       Quad Serial I/O Card makes it easy to add four high-speed serial COM
        ports to your Handheld PC Pro or notebook computer.  Each port
        operates independently and can link to an external modem, label
        printer, bar code scanner, magnetic stripe reader, GPS receiver,
        digital camera, or other RS-232 serial device.  It's ideal for
        applications that need mobile data collection from multiple sources.
       A fully integrated fixed cable maintains solid contact in high
        vibration situations, such as when the card is used with a PC
        mounted in an all-terrain vehicle.  A molded strain reflief protects
        against lateral stress and seals out dust and moisture.  A sonic
        welded case adds rigidity to resist torque that could otherwise
        crack circuit borad traces.
       Socket's High-Integration Serial (HIS) chip reduces chip count to
        improve reliability and reduce power consumption.  The Quad Serial
        I/O card uses less than 5 mA in standby mode, compared to over
        100 mA for some single-port serial PC cards.
 * Four independently configurable 16550 type UARTs run simultaneously at up
   to 115.2 Kbps and act like Windows COM ports.
 * Works with Windows-based notebooks, Handheld PCs, Handheld PC Pros and
   pen tablets.  A PC Card direct enabler for MS-DOS is also included.
 * Works in Type II or III PC Card (PCMCIA) slot.
 * Plug-and-Play and hot swapping support with Windows 95/98/2000/Me and
   Windows CE.  Uses only one interrupt line to control four ports.
 * Includes one non-removable, 24" cable that splits into four cables with
   industry standard male DB-9 connectors.
 * Ruggedized with non-removable serial cables, the Quad Serial I/O Card is
   designed to withstand stress from industrial or field environments.
 * Socket's Control Panel applet makes it easy to identify Windows COM port
   assignments.
 * Industry standard DB-9 connectors.
