User Channel Mux

Each event user can be connected to one channel, and several users can be connected to the same channel. The following table lists all Event System users with their corresponding user ID number and name. This ID number corresponds to the USER register index, e.g., the EVSYS.USER2 register controls the user with ID 2.
