Overview
The Sealevel Systems ULTRA COMM+I.LPCI is a single channel isolated low profile Universal Bus serial I/O
adapter for the PC and compatibles. Utilizing the Exar 16C850 UART with its industry leading 128 byte FIFOs, it
provides a field selectable RS-232/422/485 serial port supporting data rates up to 921.6K bps (RS-422/485).
Configure as RS-232 for standard serial COM: port requirements. Choose the RS-422 mode for long distance device
connections up to 5000ft. where noise immunity and high data integrity are essential. Select RS-485 and capture data
from multiple peripherals in a RS-485 multidrop network. Up to 31 RS-485 devices can be connected to each port to
automate your data collection. You can even mix the ports in any of the interface combinations to provide maximum
flexibility to your application. Optional Terminal Block adapters are available to simplify field-wiring connections.
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.
The ULTRA COMM+I.LPCI ships with a Low Profile PCI bracket that will only work in a Low Profile PCI slot.
If you need a standard size PCI bracket, please order Item# 7108S.
