Interrupt Selection
You can configure an interrupt request line (IRQ) with the jumper
blocks JB1, JB2 and JB3 on the Xtreme/104 Opto adapter. Please
refer to

blocks JB1, JB2 and JB3.
You are able to configure the Xtreme/104 Opto adapter for four
different IRQ modes.
Mode 1 (one IRQ) :
1. First you make sure there are no jumpers across positions
E and D on the JB3 jumper block
2. All ports interrupting on one IRQ by setting jumpers on
the A or C rows and the middle rows of jumper blocks
JB1 or JB2.
Mode 2 (two IRQs) :

2. The odd ports (ports 1, 3) interrupt on one IRQ by setting
jumpers on the B or D rows and the middle rows of
jumper blocks JB1 or JB2.
