Unlike another one I bought that claimed to do both 2-wire RS-485 AND 4-wire RS-422, this one actually does both standards very well. Connects every time and works like a champ. Highly recommend.

Working fine. No issue.

They are very easy to connect. Make sure you test the connection on the bench before installation

Had to extend length of old RS-232 network to 900 feet at 19.2 kbps half duplex. That was a perfect budgetary solution. Had to add bias resistors and no running required.

Yo lo uso para hacer pruebas en oficina y en campo, es muy bueno. Se ve de buena calidad, lo que si no puedo saber es la durabilidad, pero se ve que es buena
