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 Figure 1 and Figure 2 for a description

and location of the jumper 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. Ensure there are no jumpers across positions E and D on the JB3 jumper block.

2. All ports interrupt 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):

1. Jumper position D on the JB3 jumper block.

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.

3. The even ports (ports 2, 4) interrupt on one IRQ by setting jumpers on the A or C

rows and the middle rows of jumper blocks JB1 or JB2.

Mode 3 (two IRQs – Xtreme/104 Opto, 4 port model only):

1. Jumper position E on the JB3 jumper block.

2. The first two ports (ports 1, 2) interrupt on one IRQ by setting jumpers on the A or C

rows and the middle rows of jumper blocks JB1 and JB2.

3. The last two ports (ports 3, 4) interrupt on one IRQ by setting jumpers on the B or D

rows and the middle rows of jumper blocks JB1 and JB2.

Mode 4 (four IRQs – Xtreme/104 Opto, 4 port model only):

1. Jumper positions D and E on the JB3 jumper block.

2. To set an IRQ for Port 1 install a jumper across a pair of pins on a row and the middle

row of IRQ block JB1.

3. To set an IRQ for Port 2 install a jumper across a pair of pins on B row and the middle

row of IRQ block JB1.

4. To set an IRQ for Port 3 install a jumper across a pair of pins on C row and the middle

row of IRQ block JB2.

5. To set an IRQ for Port 4 install a jumper across a pair of pins on D row and the middle

row of IRQ block JB2.
