EXSYS EX-41010 PCI-X parallel-adapter, IEEE 1284, DB25 bus, MosChip MCS9901, Low Profile

Legacy parallel devices meet modern PCI-X infrastructure through the EX-41010, a single-port adapter built around the MosChip MCS9901 controller. Unlike generic USB-to-parallel dongles, this card places a true IEEE 1284 port directly on the PCI-X bus, eliminating driver latency and preserving full EPP/ECP compatibility for industrial printers, scanners, and control systems that demand deterministic timing.

Highlights

• Native PCI-X interface with 64-bit / 133 MHz support for high-throughput parallel communication
• One external DB25 female port compliant with IEEE 1284 (SPP, EPP, ECP, bi-directional)
• MosChip MCS9901 chipset with 16-byte FIFO buffer for smooth data streaming
• Supports both 3.3V and 5V PCI-X slots, with plug-and-play installation and IRQ sharing
• Broad OS compatibility: Windows XP/Vista/7/8/10/Server and Linux kernel 2.6.x+

In daily use

The EX-41010 excels in mixed environments where older parallel peripherals must remain in service alongside newer systems. Its low-profile bracket fits slim desktops and 1U/2U rackmount servers, while the standard-profile bracket (included) covers traditional towers. The card draws minimal power and requires no external supply, making it suitable for always-on industrial PCs. Data transfers up to 1.5 MB/s are more than adequate for dot-matrix printers, label printers, and legacy measurement equipment.
