EXSYS EX-44081 PCIe 1-Port RS-232 σειριακή κάρτα, ASIX AX99100, Low Profile

Many modern computers lack native RS-232 serial ports, making it difficult to connect legacy devices such as industrial machinery, point-of-sale terminals, or laboratory instruments. The EXSYS EX-44081 solves this by adding a single high-performance RS-232 port through a PCI Express x1 slot, ensuring reliable communication with older equipment.

Who is it for

This card is ideal for system integrators, IT administrators, and technicians who need to connect serial devices to modern desktops or servers. It suits industrial automation, retail, healthcare, and scientific environments where legacy serial peripherals are still in use.
