EXSYS EX-47030 PCI Express x1 2-Port RS232 Serial and 1-Port Parallel Combo Card

Legacy serial and parallel devices often remain essential in industrial, retail, and office environments, yet modern computers rarely include these ports. The EXSYS EX-47030 solves this by adding two RS232 serial ports and one parallel port through a single PCI Express x1 slot, enabling seamless connection of printers, scanners, POS terminals, CNC machines, and other peripherals.

Who is it for

This card is ideal for system integrators, IT administrators, and businesses that need to connect legacy equipment to modern desktop systems. It suits point-of-sale setups, industrial automation, laboratory instruments, and office environments where parallel printers or serial devices are still in use.

Main features

• Two high-speed RS232 serial ports with DB9 male connectors, supporting data rates up to 230.4 Kbps.
• One parallel port with DB25 female connector, supporting EPP, ECP, and SPP modes with data transfer up to 1.5 MBps.
