Perle Systems Technical Note
Adding Windows COM ports with Multiport Serial Cards
Perle Multiport Serial Cards
Problem Overview
 Windows has the ability to add multiple COM ports to a server. These
can be used for anything from data acquisition ports to peripherals such
as modems or CAD/CAM equipment. Embedded operating systems and hardware
are creating new applications and many times additional I/O ports are
needed to control devices, such as in the case of building retail kiosks
(many which are PCs with a design around them.) Many times a server needs
to be installed in a branch location, as in a gas station, to collect
data from multiple devices and this data will be uploaded to central site
locations.
Solution
Perle offers 4 to 128 ports per card for creating additional COM ports
on Windows servers. These ports are bi-directional pipes to talk to device equipment. It's a very
simple setup.
