The Lava DSerial-550 is still our most popular product. It allows you to connect two high speed serial peripherals (modems, digital cameras, PalmPC's, UPS's, TAPI telephones) to one card. The Lava DSerial-550 incorporates two high-speed 16550 UART serial ports capable of handling data throughput rates up to 115.2k bps. Each of the card's serial ports is independently configurable as Com 1 through Com 6, and selectable for any of IRQ 2/3/4/5/7/10/11/12/15. The Lava DSerial-550 makes sure that your external modem, PalmPC, digital camera or POS devices perform to their full capacity. Specifications:
