NetBox – Multiple Xbus/XpressNet

NetBox
Netbox allows multiple cabs to be conected to the Xbus/XpressNet using RJ12 or DIN5 plugs. Useful when you have multiple throttles to connect to the command station. It has two RJ12 plugs for Lokmaus type throttles and a DIN5 plug for Lenz throttles with 4 wires, two more RJ12 plugs with 6 wires permits to expand the bus between NetBoxes and have two additional signals (usually C and D for additional boosters).

The schematics is very simple, only plugs and two LED. A green LED indicates power on the bus, and the red LED indicates a problem: the wire is inverted.

It was successfully used in the Plataforma-N modular meeting in Salon del Hobby 2006 (Barcelona)

Another more simple and economical way to connect multiple throttles is to use comercial telephone Plugs with several plugs (check wire order):
