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.
