EXSYS Placa Serial PCI RS-232 de 4 portas com chipset FTDI (EX-41084)

Legacy serial devices such as industrial controllers, point-of-sale terminals, and laboratory instruments often require reliable RS-232 connectivity, but modern computers rarely include enough native COM ports. The EXSYS EX-41084 solves this by adding four high-speed RS-232 ports through a single PCI slot.

Who is it for

System integrators, industrial automation engineers, and IT professionals who need to connect multiple serial peripherals to a desktop PC. It suits applications requiring stable, low-latency communication across Windows, Linux, or macOS.

Tips

Install the driver before inserting the card to avoid conflicts. For industrial environments, secure the card bracket firmly and use shielded serial cables to minimise interference.
