EXSYS EX-44012 scheda PCI Express doppia porta parallela EPP/ECP, MosChip MCS9901CV, low profile

Expand legacy parallel connectivity on modern systems with the EXSYS EX-44012 PCI Express dual parallel port card. Built around the MosChip MCS9901CV controller, this card delivers two high-speed IEEE 1284 parallel ports via a single PCIe x1 slot, supporting SPP, PS/2, EPP, and ECP modes for broad compatibility with printers, scanners, CNC machines, and other parallel peripherals. Each port features a 16-byte FIFO buffer and data transfer rates up to 1.5 MB/s, ensuring reliable, low-latency communication even in demanding industrial or office environments.

Advantages

Dual DB25 female ports enable simultaneous connection of two parallel devices without additional hardware. The PCIe 1.0a x1 interface provides 2.5 Gbps bus bandwidth, eliminating bottlenecks for legacy I/O. Automatic IRQ and I/O assignment by BIOS simplifies installation, while support for Windows (XP through 11 and Server) and Linux kernel 2.6.x+ ensures cross-platform compatibility. Both standard and low-profile brackets are included, making the card suitable for slim desktops and 2U rackmount chassis. Bus-powered operation requires no external power supply, and compliance with CE, FCC, and RoHS guarantees safety and environmental standards.
