Interrupt Jumpers
are provided in addition to the COM1 (IRQ4) and COM2 (IRQ3) jumpers. IBM PC BASIC uses interrupt driven communications, and
therefore requires that the COM1 (or COM2) interrupt jumpers be installed when doing communications using COM1 (or COM2)
from BASIC.
Group B and C Jumpers
on the AC24AT and B1 through B8 and C1 through C7 on the AC422AT. This arrangement is suitable if the adapter card is being
used to communicate with an OPTOMUX network. For other possible configurations, refer to the figure below.
If you need to select a specific interrupt line for your software, jumpers for interrupt request lines IRQ2 and IRQ5 through IRQ7
The figure below shows the normal jumper arrangement for jumper positions B1 through B7 and C1 through C7
The adapter card is now ready to be plugged into any open slot of the computer.
