Control Bus Structure
The Network Control Bus structure follows the standard MIDI bus defini-
tion. The NCB is defined as a closed chain of units. This means that the NCB
OUT of the last unit must be connected to the NCB IN of the first unit in the
NCB chain. To avoid problems with the control of Triton Plus units the
installer/user has to assure that the bus structure is installed according to
this definition.
Note The total number of Triton Plus devices in an NCB chain is limited to 50.
Maximum Distance Between NCB Devices
The standard MIDI definition allows a maximum cable length of 200-250
meters between two devices. Longer distances can be made with MIDI
repeater units. To avoid grounding problems all NCB ports have opto-cou-
pled inputs.
