iPC-I 320 Manual, Version 2.8
3.1.2 Setting the PC Interrupt
The required PC interrupt is set with the jumper board JP27 by closing the
jumper belonging to the required IRQ.
Only one interrupt may be selected for the iPC-I 320!
If no interrupt is required, no pin may be bridged by JP27.
The factory setting of the interface is IRQ 5.
The iPC-I 320 can also be operated with an 8-bit slot. Then interrupts 10-15 are
not available.
It should be ensured that no other system component is occupying the selected
interrupt, except for cards which work with shared interrupts.
In PC systems it is possible that several cards share an interrupt. Further
information on this subject can be found in the hardware manuals for the PC.
The iPC-I 320 supports shared interrupts by enabling the level of the interrupt
impulses to be adjusted with switch 7 of the DIP switch SW1 (with PC/104
interface via jumper board JP1).
IRQ level
ISA slot, AT/ISA96
SW1-7
PC/104
JP1
Low impulse (default)
OFF
LOW
High impulse
ON
HIGH
For shared interrupts, the switch SW1-7 must be set to OFF, with the PC/104
version the jumper JP1-LOW must be closed.
With the PC/104 interface, both jumpers must never be closed at the same
time!
On the iPC-I 320/104 interface it is possible to connect a pull-up resistor with a
value of 15 kOhms to the interrupt lead by closing the jumper JP3. When the
interface is delivered, the jumper is open.
