1784-PKTX Alternative: USB to DH+ Cable for Modern Windows OS

A reliable 1784-PKTX alternative is critical for maintenance teams managing legacy Allen-Bradley systems. The original PCI interface card from Rockwell Automation was the industry standard for Data Highway Plus (DH+) connectivity, but is now completely obsolete and incompatible with modern 64-bit PCI Express slots and Windows OS.

The ANC-120e delivers the definitive 1784-PKTX alternative. It replaces complex internal PCI cards with a pocket-sized, plug-and-play USB to DH+ cable that connects modern Windows 10 and 11 workstations directly to PLC-5 and SLC 5/04 controllers.

1784-PKTX Alternative: Technical Features & Specifications

• Plug-and-Play USB: No PCI slots or desktop chassis needed; works over standard USB ports.
• Full 64-Bit OS Support: Seamless operation on Windows 10 & Windows 11 with RSLinx Classic.
• Auto-Baud & Auto-Polarity: Automatically senses 57.6k, 115.2k, and 230.4k DH+ baud rates.
• Direct Compatibility: Full online monitoring, upload/download for PLC-5 (all models) and SLC 5/04.
• Includes Cables: Comes with 8-pin Mini-DIN and 3-pin Phoenix cables in the box.
