This is CTS with 6 adresses on side A and 20 adresses on side B.
Each side, that is side A or side B, can be either the inputs or outputs the system.
When the inputs are on the side A, the outputs are on the side B, and vice versa.
Addresses on the side B are actually combinations of addresses on the side A.
Here is the address 1 on the side A active and partially all other addresses on the side B that are related to that address.
Here are the addresses 1,3 and 5 on the side A at the same time active and this time is the adress 6 on the side B fully active.
To put it differently, if the address 6 on side B is active, addresses 1,3 and 5 on the side A will be the same active.
This is a video of CTS basic behavior when distributing energy or matter.
