Placa PCIe EXSYS EX-45032IS Dual Serial RS-232, Low Profile

Legacy serial devices often lack a way to connect to modern computers that no longer include RS-232 ports. The EXSYS EX-45032IS solves this by adding two high-speed RS-232 serial ports through a PCI Express x1 slot, enabling reliable communication with industrial equipment, POS terminals, and other serial peripherals.

Who is it for

System integrators, industrial automation engineers, and IT professionals who need to connect legacy serial devices to current desktop systems. Its low-profile form factor makes it suitable for small form factor and slimline computers, while the included standard bracket ensures compatibility with full-height cases.
