4. Connections
Danger of confusion!
Note that identical plug connections are used for different bus systems:
RJ12: LocoNet and XpressNet
RJ45: EasyNet, BiDiB, S88-N and LAN
Therefore, be very careful when plugging in the connection cables! Make sure that you do
not accidentally plug the cables into the wrong sockets! In the worst case, (even irreparable)
damage can occur to your mc² and/or the connected devices. This applies especially to
EasyNet devices, s88 modules and BiDiB components.
If you plug connection cables with RJ12 plugs into RJ45 sockets, the connection pins in the
socket will be bent. In this case, we recommend sending in the central unit for repair.
Avoid these risks by marking the connection cables (e.g. with the labels enclosed with the
delivery) and/or using different coloured cables for the different bus systems, e.g.
 red for EasyNet
 blue for the s88 bus
 green for the BiDi bus
 grey for the Ethernet (Lan)
Plug & Play
You can establish or interrupt connections to and from external devices to your mc² at any
time - even during operation (plug and play).
