If I want to make a mobility ring with 2 or 3 ELU31's in one magazine (LBP20) what type of cabling do I need?

Hello,

As far I know the bus synchronization in an LBP20 magazine works over its backplane. If you use only one magazine you don't need any cables for synchronization.

The first Board in the magazin must always have a Sync cable.
If all boards are in the same magazin you must loop the Tx and Rx of the first board.

Is this a TSR 901 1219/3000 or TSR 901 1223/3000 cable or a different type

If LBP20 no Frontcabling within the magazin is needed. But each first Board of a magazin is connected via frontcable to the first board of the next magazin and so on.
