4.3. Pin-out and cable type
The pin-out of all Network MIDI ports follows the standard MIDI specification.
A 1 to 1 cable with 5pin DIN connector is used. The following pin-out is used:
1 - n.c. 1 - n.c.
2 - shield # # # # # # # # # # # # # # # # # # # # # # 2 - shield
3 - n.c. 3 - n.c.
4 - data - - - - - - - - - - - - - - - - - - - - - - - - - - - - - 4 - data data lines must
5 - data - - - - - - - - - - - - - - - - - - - - - - - - - - - - - 5 - data be twisted pair
The standard MIDI specification recommends the use of shielded twisted pair cable types for interconnection between the
units.
4.4. MIDI bus structure
The Network MIDI bus structure follows the standard MIDI bus definition.
The Network MIDI bus is defined as a closed
chain of units. This means that the MIDI OUT of the last unit must be connected to the MIDI IN of the first unit in the
MIDI chain
. To avoid problems with the control of Network
units the installer/user has to assure that the bus structure is installed according to this definition. The total number of MIDI
devices in a MIDI chain is limited to 50.
4.5. Maximum distance between MIDI devices
The standard MIDI definition allows a maximum cable length of 250 meters between two devices. Longer distances can be
made with MIDI repeater units. To avoid grounding problems all Network MIDI ports have opto-coupled inputs.
5. Router configuration
5.1. Router address
Switch 1 - 4 on the configuration switch SW A set the router’s address for communication with the
i-Control software and other units in the MIDI bus system. The i-Control control screen and the panels on the MIDI bus
dedicated to operate with the router have to have the same address. If several routers are combined to form an Audio Follow
Video, RGB or similar system, these routers have to have the same address.
The addresses can be switched according to the following pattern:
- means switch down
* means switch up
Default address is 0.
