Different signal flows can be supported.

Merge within Stage Precision seperated networks

By using multiple networks, it´s still possible to have the same patch for fixtures.
SP is receiving the DMX network stream on one deticated network interface and send out on an other interface.
The merging will happen within SP.

Merge within Stage Precision same network

By using one network, it´s necessary to use seperated universes for receiving and sending.
SP is receiving the DMX network stream on the same network interface as well as the sending values.
The merging will still happen within SP.

Merge within hardware nodes

Also hardware nodes can take care about the merging.

Merge within a lighting desk

Also a lighting desk can take care about the merging.

Stand alone (without any lighting desk)

It´s also possible to run SP only instead of using an addional lighting desk.
