On the input of the ssc, you have 4 connections: a pixelnet data pair (orange/white-orange), ground and +12v.
On a v1 ssc, there are three wires for ground and three wires for +12
On a v2 ssc, the same three wires get twisted together for ground and the same three for + 12
You can not skip the ssc.
On the output of the ssc, you have ground, +12, and 1 wire for pixel data (uses ground for the data return).
Pixelnet and pixel data are not the same. Pixelnet is a balanced rs-485 type data stream, while the pixel data is an unbalanced bit stream. There are also data speed and bit encoding differences. The ssc coverts pixelnet to pixel data.
Since you are talking about skipping the passive hub, my assumption is that you are making a custom wiring harness using cat 5 patch cords with one end cut off . The pixelnet data must be a twisted pair - you cannot go very far with a home brew twisted pair.
If you are thinking about splitting the pixel data after the ssc, you are entering uncharted waters...
