Interfacing to the MX10, JMRI, etc. This page is under construction, trying to list all the interfaces to the MX10 system, and I will be concentrating on things used in the US first. JMRI This is the most used "interface" to DCC systems in the US. The MX1 was originally supported on USB I believe. Recently I think Ethernet is supported. I have yet to check this interface out. Roco There's kind of 2 ways to interface. One way is the Roco Z21 system, and at first it seemed this was recommended for the Roco phone app too. I found out that putting the MX10 on your own network, via Ethernet, would give the Roco app all that it needed for a phone with the app connected to your network, normally by Wi-Fi.
