OMG-COMM2-EX $199 2-port RS-232/422/485 interface with
extended “AT” interrupts
The OMG-COMM2-EX is a PC bus
plug-in card based on the 16550
FIFO buffered UART, which is
compatible with the standard 8250.
This dual channel asynchronous
serial communication card utilizes
balanced differential drivers and
receivers to provide RS-422 and
Dual Port RS-232/422/485 Interface
with Extended “AT” Interrupts

Selectable and sharable extended
“AT” interrupts for each port
increase the OMG-COMM2-EX
versatility. Distances of 5000 ft. in
noisy industrial environments are
easily accommodated. The
OMG-COMM2-EX is also capable
of RS-232 for applications
requiring shorter distances and
RS-232 compatibility. Signals are
transmitted and received via two
9-pin sub-D connectors. Bit
character lengths of 5, 6, 7 or 8,
and odd, even or no parity are
all available.
WIN 95/98/Me/NT/2000/XP
drivers are included as well as
support for Linux, QNX and DOS.
Thedrivers provide IRQ sharing,
advanced UART support and
serial diagnostic utilities.
