The position of the Jumper Switches,
Edge/Level and IRQ Shunts for ISA cards.
Manual Interrupt Settings. Rev3 EasyIO4 requires
manual selection of IRQ settings. Jumper positions are shown on the
board itself. The edge/level IRQ setting should be set to the default
of edge triggered.
Edge/Level Jumper (J1)
Shared interrupts are not supported on EasyIO
4 (Rev. 3.0). The shunt must be set to 'Edge', as shown:
'Level' is used with EasyIO 8-M when sharing
interrupts between multiple boards in an EISA bus architecture system.
IRQ Jumper (J2)
The default IRQ shunt position is 15. If IRQ
15 is already in use, select an alternative by installing the shunt
in either 3, 4, 5, 7 10, 11, or 12.
Jumper J2 is shown above in interrupt
position 15 (default).
