Don't plug into your router. Its a TTL serial interface.
This look like an XM10 interface to me. More info here
Hello, so I bought one of these on ebay cheap, thinking it was a form of CM11/12. Th case is similar to that of the CM15.
It arrived with a network plug on the end of it's cable, is it possibly the wrong lead or is this something different? I cannot ssem to find much info on the web about this unit, so thought I would as here before plugging into my router or changing the cable to one from a CM11.
