UC400ETH -> 2 UCSB?

[FerrumD]

Hi,

As I‘m about to add an ATC (umbrella type, servo driven) to my milling machine I ran into the following „issue“:
My current UC400ETH + UCSB is now officially out of outputs… I‘ve used them up all, for various accessories (3 Axis, air blast, flood, mist etc…)… which brings me to the question whether it‘s possible to add a second UCSB or maybe the UCBB?

The UCBB is not compatible with the UC400ETH, because the UCBB has one standard and one input pinout port while the UC400ETH has 2pcs standard pinout port.
The UCBB is compatible with the UC300ETH-5LPT because it has both standard and input pinout ports, so you can connect max. 2pcs UCBBs to the UC300ETH-5LPT.
The UCSB is compatible with both ports of the UC400ETH, so you can connect 2pcs of UCSBs to the UC400ETH.
