Automation Blog Comments:

“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, that Rockwell cable now lists for a whopping $3,140, while the ANC-120e lists for $995. But how well could a third party DH+ cable really work?”
