Works great for RS-485 AND RS-422
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.

RS 232 TO RS 422
They are very easy to connect. Make sure you test the connection on the bench before installation

Muy bueno
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

Useful little device
Tested it at 19.2 Kbps and works great. No need for an external power supply as it is powered by the RS 232 port.
