Independent Industry Review
Watch Shawn Tierney from The Automation Blog demonstrate the seamless setup and performance of the ANC-120e on a live DH+ network.
“In today’s episode of The Automation Podcast I take a look at the ANC-120e USB to Data Highway Plus converter… Now you may be asking yourself why the folks over at Automation Networks would release a USB to DH+ converter when Rockwell already makes the 1784-U2DHP? Well if you haven’t looked lately…”
Seamless Network Topology
Yes, absolutely. The ANC-120e is widely recognized as the premier, cost-effective alternative to the discontinued and highly expensive Allen-Bradley 1784-U2DHP cable.
It acts as a seamless USB-to-DH+ bridge, allowing you to connect modern laptops and PCs directly to Data Highway Plus networks to program, monitor, and troubleshoot legacy PLC-5 and SLC 5/04 processors without requiring obsolete hardware.
Yes. Unlike legacy cables that struggle with modern operating systems, the ANC-120e is fully compatible with both 32-bit and 64-bit modern OS, including Windows 10 and Windows 11.
For facilities still running older infrastructure, the device also maintains full backward compatibility with legacy systems such as Windows XP, Windows 7, and Windows 8.
