Power connections

Be aware that you never put the power (+12V) of the network from one network segment to another.

Example:

  • A 32-8 is powered by the net and can power other nodes by the network. (Bar 2)
  • A ABC is powered by the net and can power other nodes by the network. (Bar 1)
  • But when you connect these 2 nodes on the same network you may only connect the network line between the 2 nodes!
  • Also connect two 32-8 nodes on the same network only with the network line.
