EXSYS EX-44343 PCIe Card – 2x RS-232 Serial + 1x Parallel

Expand your desktop's connectivity with this PCI Express x1 card, adding two RS-232 serial ports and one IEEE 1284 parallel port. The EX-44343 delivers legacy device support with a 16-byte FIFO buffer and data rates up to 230.4 Kbps per serial port, while the parallel port handles ECP transfers at 2.5 MB/s. Compatible with Windows and Linux, it fits standard profile slots and includes a low-profile bracket.

Advantages

Adds two high-speed RS-232 ports and one parallel port through a single PCIe x1 slot. The 16C550-compatible UART with 16-byte FIFO reduces CPU load and ensures reliable data transfer. Plug-and-play installation simplifies setup, and the included low-profile bracket allows use in slim desktops.

Suitable for

• Connecting legacy serial devices such as barcode scanners, POS terminals, and industrial equipment
• Adding parallel port support for older printers and specialized hardware
• Systems with limited expansion slots that require both serial and parallel connectivity
