Introduction
Overview
The Sealevel ULTRA COMM+422.PCI is a four channel PCI Bus serial I/O
adapter for the PC and compatibles supporting data rates up to 460.8K bps.
RS-422 provides excellent communications for long distance device connections
up to 4000ft., where noise immunity and high data integrity are essential. Select
RS-485 and capture data from multiple peripherals in a RS-485 multidrop
network.
In both RS-485 and RS-422 modes, the card works seamlessly with the standard
operating system serial driver. In RS-485 mode, our special auto-enable feature
allows the RS-485 ports to be viewed by the operating system as a COM: port.
This allows the standard COM: driver to be utilized for RS-485 communications.
Our on-board hardware automatically handles the RS-485 driver enable
