The OMG-ULTRA-SIO provides the
PC with two isolated RS422/485
Asynchronous links to data collection
and other devices. Isolation is
important in installations where the
equipment connected to the PC is
either located far from the host system,
or on a different power transformer
circuit.
The optical isolation feature of
the OMG-ULTRA-SIO-I eliminates
the risk of ground loop current,
a commonly neglected and
misunderstood phenomenon which
leads to data errors and destruction
of communications equipment.
Individually selectable addresses
and extended “AT” interrupts allow
for seamless integration into
Windows and OS/2 systems. The
OMG-ULTRA-SIO appears to the
host system as a standard COM:
port requiring no special drivers
or additional software.
Software
WIN XP/Vista/7 drivers are included
as well as support for Linux.
The drivers provide IRQ sharing,
advanced UART support and
serial diagnostic utilities.
