Mode 2 (two IRQs)

Mode 2 allows you to select one IRQ for ports 1 and 3, and

another IRQ for ports 2 and 4. Please follow these steps to choose

this mode:

1. Choose an available IRQ for ports 1 and 3 and an available

interrupt for ports 2 and 4 .

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

position and DIP switch 5 in the off position.

3. Install a jumper across the corresponding IRQ pins on the

A/C row and the middle row of jumper block J2 for ports 1

and 3. Then install a jumper across the corresponding IRQ

pins on the B/D row and the middle row of jumper block J2

for ports 2 and 4.

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

not contacting more than one pin.
