Danpex AN-520BT 16-Bit 4-in-1 ARCNET Card – Legacy Series

Technical Dossier

Product Details And Specifications

The Danpex AN-520BT is a 16-bit ISA bus ARCNET network interface card supporting four ARCNET topologies in a single adapter — coax (RG-62), twisted pair, fiber, and active hub configurations. As a legacy industrial NIC discontinued from mainstream production, the AN-520BT represents a classic supply continuity challenge: the installed base in legacy SCADA, DCS, and factory automation systems remains active, but OEM replenishment channels have long since closed.

Part Number Verification & Cross-Reference: Our technical team validates every AN-520BT against original Danpex documentation to confirm firmware revision, hardware revision, and compatibility with target systems before dispatch review. We proactively flag known compatibility issues — for example, certain ARCNET controller chipset revisions that may require driver updates on specific OS versions.

Q: Is the AN-520BT compatible with Windows 10/11 or Linux?
A: The AN-520BT is an ISA bus card and requires a system with an ISA slot. It is not compatible with modern PCI/PCIe-only systems. Driver support is limited to DOS, Windows 95/98/NT/2000, and certain real-time OS environments. If you are running a legacy system with ISA slots, compatibility is typically confirmed.
