EXSYS EX-44344 2S/2P PCI-Express Multi I/O Card with Octopus Cable, RS232 & IEEE1284

Add two RS232 serial ports and two IEEE1284 parallel ports to a desktop PC through a single PCI-Express x1 slot. The EX-44344 is used in industrial PCs, point-of-sale systems, and legacy equipment setups where multiple serial and parallel peripherals must be connected. The included 40 cm octopus cable breaks out to two DB9 male and two DB25 female connectors, keeping the rear panel tidy while the low-profile bracket supports slim cases.

Why choose it

The ASIX AX99100 chipset provides reliable multi-I/O expansion with broad OS support. Both serial and parallel ports are on a single card, reducing slot usage and simplifying cable management.

Ideal use cases

• Connecting legacy serial devices like barcode scanners, scales, or industrial controllers
• Driving parallel printers or CNC machines that require IEEE1284
• Upgrading a modern PC to support older peripherals in POS or kiosk systems

Good to know

The octopus cable is 40 cm long, allowing flexible routing inside the chassis. The card is bus powered, so no external power supply is needed.
