MultiPort Communications Cards

These add-in cards for PC's expand the serial
communications capabilities of that PC beyond the one or two ports that it came with.
These ports can be used in Direct Connect applications,
or to communicate with other hardware devices.
Greco Systems can provide several different cards,
depending on the number of ports required (4, 8, 16, and 32 port models are available;
call for other sizes). Most cards provide ports that meet RS-232 electrical
specifications, but cards are available for other systems.
