I just started to test this pretty module, using a usb RS485 adapter in my linux pc. Using gtkterm as terminal software and following the document it was easy to send commands to the module. I used a roll (100 meters) security cable (2x0,5 ; 2x0,22 pairs) using only the 2x0,22 for rs485 signal, it seems perfect.

tutto ok, arrivati sani e salvi. L'unica cosa e' l'assenza di informazioni per l'utilizzo. Devo inventarmi qualcosa...

Auf den ersten Blick sauber verarbeitet. Die Verpackung war, naja ich sage mal nicht optimal. Vollständige Funktion konnte noch nicht überprüft werden, nur die Eingänge arbeiten bis jetzt. Habe bis jetzt auch keine komplette Doku gefunden. Aber alles in allem super für diesen Preis.
