Selecting the Interrupt Line Number

The multiplexer module generates interrupts at the end of a downloaded scan list. The interrupt line number switch determines which backplane IRQ line will be used. Different mainframes and resource managers recognize different backplane IRQ lines. The interrupt line number must be set to the line number your system is programmed to recognize. Refer to your mainframe manual.

Refer to Figure 2-5 to change the interrupt lines. Valid line numbers are from 1 to 7. Set the interrupt line number to the mainframe interrupt handler number.
