Introduction
Overview
The Sealevel Systems ULTRA 530.PCI is a one channel PCI Bus serial I/O adapter for the PC and compatibles. It
provides one field selectable RS-232/422/485/530 serial port supporting asynchronous data rates up to 460.8K bps
as well as isochronous data rates up to the speed of the supplied clock. Now, with this card, you can use your
standard communications software and connect over a clocked digital communications line.
Configure the port as RS-232 for standard serial COM: port requirements. 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 both RS-232 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. UART upgrades are available providing 32, 64 and 128
byte FIFOs.
