Mode 3 (four IRQs)

Mode 3 allows you to select a unique IRQ for each port. Please

follow these steps to choose this mode:

1. Choose available and unique IRQs for ports 1, 2, 3 and 4.

2. Make sure that switch block SW1 has DIP switch 4 in the off

position and DIP switch 5 in the on position.

3. Please take note of the two solid white lines just above

jumper block J2. These lines mark the A, B, C and D portions

of the corresponding row of jumper pins.

4. First install a jumper across an IRQ pin on the A portion of J2

and the corresponding pin in the middle row of J2 for port 1.

5. Next install a jumper across an IRQ pin on the B portion of J2

and the corresponding pin in the middle row of J2 for port 2.

6. Then install a jumper across an IRQ pin on the C portion of J2

and the corresponding pin in the middle row of J2 for port 3.

7. Finally install a jumper across an IRQ pin on the D portion of

J2 and the corresponding pin in the middle row of J2 for port

4.

8. Ensure that all other unused jumpers on J2 are removed or

not contacting more than one pin.

Note:

In Mode 3, ports 1 and 2 are limited to IRQs 3 to 9/2 and ports 3

and 4 are limited to IRQs 10 to 15
