Thanks for that posting. I've also used a lot of LAN or USB to RS422 converters, as well as RS232/422 adapters on my Z3801A.

Before you commit to Amazon, note there are many Ethernet/RS422 offerings on eBay.

There are also inexpensive bare-board versions like:


And, if you have a couple of 422 devices, consider the economics of a 4-port unit like:


I have no affiliation with any seller, nor have I tried these specific items. But they are inexpensive and look worthwhile. OTOH, I'm nervous about any networking product made in CN even if its web interface says "IOT Experts" and "Be Honest, Do Best!"...
