For the default setting the jumper I1, I2, I8, IR11, IR12 and IR15 are active
(closed).
The interrupts IRQ9 and IRQ10 are added for PC application only. For a
correct reproduction of the interrupt signals it is necessary that the jumper
IR9 to IR15 are not activated. To activate the interrupt request signal the
corresponding jumper must be closed.
To avoid possible conflicts with already existing plug-in-boards in your sy-
stem, deactivate those jumpers on the COM board, that are not longer
needed (opening the jumpers).
