The OMG-ACB Series provides the
PC-based system with single/dual
high-speed synchronous/
asynchronous links to instruments
requiring extremely fast data flow.
The RS-422 communications
standard allows the OMG-ACB
to communicate reliably at high
speeds under harsh conditions,
which makes it an ideal solution for
industrial environments.

Line noise, present in industrial
environments, is eliminated over the
RS-422 line. By utilizing RS-422,
factory applications requiring long
distance communications operate
with high data integrity. Signals are
transmitted and received via
25-pin sub-D connector(s). The
OMG-ACB-II is also capable of
RS-232 for applications requiring
shorter distances and RS-232
compatibility.

Balanced differential drivers
and receivers are utilized to
provide RS-422 and RS-485
communications. Selectable
interrupts (IRQ levels) increases
the card’s versatility. Distances
of 5000 ft in noisy industrial
environments are easily
accommodated with the OMG-ACB.
