Shared IRQ Mode

The 3PXCC4A card has the ability to share interrupts among its ports. Shared IRQ mode should only be used if your software supports this feature. If you are writing your own software, B&B Electronics’ SimpCom V1.04 and later serial communications library supports this feature.

When sharing ports, use JP5 to set each of the ports to be used in shared mode to the SHARE position. JP6 must also be set to the SHARE position. Each of the ports set to SHARE will use the Port A IRQ. Therefore when sharing IRQs among two or more ports, Port A must always be one of the shared ports.
