Bus Panel

Click the menu “Setup”-> “Bus Setup…” to open the dialog.
The instrument has 32 signals channels, A0 ~A15, B0~B15. You can assign the parts of them to some bus.
The list box contains all of the bus; you can add or delete the bus.

For example: Assign a bus “My Bus” which has 7 signals “A0, A1, A2, A3, A4, A5, and A6”.

  1. Click the button “Add”. Then a new bus is added to the list.
  2. Click the pane under the A0, A1, A2, A3, A4, A5, and A6. If the pane is filled with red, it means you have added the signal to the bus.
