Introduction
Overview
The Sealevel Systems ULTRA 485.PCI is a one channel PCI Bus serial I/O adapter. It provides one field selectable
RS-422/485/530 serial port supporting asynchronous data rates up to 460.8K bps.
Choose the RS-422 mode 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 multi-drop network. Up
to 31 RS-485 devices can be connected to each port to automate your data collection.
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.
