We sell both cables and both do the job as intended, the Allen Bradley cable uses the U2DHP driver in RSLinx and the ANC-120e uses a TCP Linx Gateway driver, you will drill down with both cables to see the 5/04 processor or the PanelView
The screenshot below is from the ANC120e with RSLinx and the driver setup, connecting to a SLC using the programming port on the SLC
This is the link to the ANC120e, it comes as pictured and as a complete kit with the PLC5 and Phoenix adapters https://www.plccable.com/allen-bradley-1784-u2dhp-alternative-usb-to-data-highway-plus-dh-anc-120e/
