Technical Description
The Sealevel Systems ULTRA COMM+I.PCI provides a PCI interface adapter
with an isolated asynchronous serial port providing a versatile interface, field
selectable as RS-232 for modems, printers and plotters, as well as RS-422/485
for industrial automation and control applications. Isolation is important in
installations where the equipment being connected to the PC is either far from
the PC, or on a different power transformer circuit. Ground loop current is a
commonly neglected and misunderstood phenomenon that leads to data loss and
the destruction of communications interfaces.
The ULTRA COMM+I.PCI utilizes the 16C850 UART. This chip features
programmable baud rates, data format, interrupt control and industry leading
128-byte FIFOs.
