The OMG-ULTRA-485-PCI is a
single channel PCI bus serial I/O
adaptor. It provides one field
selectable RS422/485/530 serial
port supporting asynchronous data
rates up to 460.8K bps.
The OMG-ULTRA-485-PCI utilizes
the 16850 UART communications
chip which features programmable
baud rates, data format, interrupt
control and 128 byte FIFO.
Choose the RS422 mode for long
distance device connections up to
4000 feet where noise immunity
and high data integrity are essential.
Select RS485 and capture data
from multiple peripherals in an
RS485 multi-drop network. Up
to 31 RS485 devices can be
connected to each port to automate
your data collection.
In RS485 mode, the special auto-enable
feature allows the RS485
port to be viewed by the operating
system as a COM port. This allows
the standard COM driver to be
utilized for RS485 communications.
The on-board hardware
automatically handles the RS485
driver enable.
