DFlex-4/104 User's Manual, ver. 0.04

You are able to configure the DFlex-4/104 adapter for three

different IRQ modes.

■

Mode 1 (one IRQ): all ports interrupting on one IRQ

■

Mode 2 (two IRQs): odd ports (ports 1 and 3) interrupt on

one IRQ and even ports (ports 2 and 4) interrupt on another

IRQ

■

Mode 3 (four IRQs): each port interrupts on it’s own

interrupt

Mode 1 (one IRQ)

Mode 1 allows you to select one IRQ for all ports. This mode is

recommended for most installations. Please follow these steps to

choose this mode:

1. Choose an available IRQ you wish the ports to interrupt on.

2. Make sure that switch block SW1 has DIP switches 4 and 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.

4. Ensure that all other jumpers on J2 are removed or not

contacting more than one pin.
